Pinkbike Poll: Has Your Shock Ever Failed?

Recently, Vorsprung Suspension published a pretty interesting video making the case that shocks with a clevis link (above) or trunnion mount (right) could potentially accelerate wear due to the lateral loads the shock experiences when the frame flexes. Trunnion-mounted shocks connect to the frame with two widely-spaced bearings, making for a stiff connection. This means any lateral movement at the other end has to be accommodated by the shock bending. Clevis links increase the leverage over the shock, meaning a given lateral force is more likely to cause the shock to buckle or bind, making it unable to absorb bumps, or leading to the shock wearing out or even breaking.
Standard Eyelet vs Trunnion
A trunnion mount (right) creates a stiffer connection to the frame.


Personally, I've seen several shocks misaligned in the frame, and sometimes visibly move side-to-side as the frame flexes. This does seem to reduce sensitivity, but I've only ever had two shocks fail - one was the notorious first-generation Cane Creek Inline DBair, and another was a first-generation Fox Float X2. In more recent years, however, shocks seem to hold up pretty well in my experience.

Trawling the PB forums, there are a few horror stories of broken shocks, but is it all that common?

What do you think?

Have you ever had a shock fail?

By fail I mean it can't be fixed with fresh oil and seals.



When was the last time your shock failed?



How often do you service your shock?

 I'd count "spewing oil and total loss of pressure" as a "failure" even if it can be fixed with new oil and seals, personally.

 Same. In which case, count me in for "a bunch"

 This exactly. I have a hard time thinking trunnion is the problem when my DPX2 nukes its damper internals twice a year.
  • 5 0
 Yeah exactly. That is a big fail and that has happened to me 2-3 times with current bike (few year period) once during a big DH day, I cut That Some slack since it’s a trail bike, but it’s happened before in less dramatic fashion where all of a sudden the bikes a low rider sitting halfway in its travel. One thing I will say is15 bucks for a UNIVERSAL fox repair kit that you can pick up anywhere is a great move by Fox. I can accept products that fail every once in a while as long as repairing them isn’t a huge PITA or expensive. I’d take a smidge less reliability to maintain a light high performance bike. I keep a rigid steel bike for unwavering reliability.

 @CTDchris:

By "UNIVERSAL" do you mean the 803-00-142 air sleeve kit? That won't really solve any issues other than maybe an air leak. Air leaks are super rare.
  • 8 0
 Yup. Shock stays packed after a big hit? That's a failure, even if all I need to do is pull it apart and relube all the things.

 @RoboDuck: I think you misspelled, "I need a different shock"
  • 14 2
 I had multiple rides ruined by a stuck down Monarch. The fix was as simple as removing and cleaning the the air can since some grease had plugged up the pos/neg transfer port. I am easily able to do this myself with no new parts but not trail side so for me, walking back 4 miles to the trailhead with a stuck down shock counts as a failure.

 @ihertzler I'd agree with you. Anything that renders the shock unable to perform as per normal, meaning a malfunction that prevents the bike being ridden normally, should be considered a "failure", even if it's not severe and it is fixed easily.

I think the poll should perhaps say "have you had a shock fail in significantly less time than the manufacturer's service interval, or in some manner (eg snapping a shaft) that is not related to maintenance of the shock" if the goal is to discern whether or not the frame has a significant influence.

With that said, seals are wearing items like tyres or chains or anything else - if they simply fail because they're worn out after a reasonable period of time, that's a different issue and generally not a design problem. If your trunnion mounted shock "suddenly" started leaking after 200hrs of riding without service, that's probably not related to it being trunnion mounted, and more related to the amount of normal wear the seals will see over that time. Did the frame cause it? Have you landed sideways hard enough to bend your frame out of alignment without noticing? Did the shock manufacturer's QC cause it? Did poor design of the shock cause it? Did you point a pressure washer at your bike and ram a ton of dirt and water into the seals? Do you frequently ride in moon dust or mud? All these things could be some or all of the cause. Frames are a significant part of it but they aren't the whole picture.

It is worth noting that we see a biased sample - we see tons of the broken stuff, but we don't really know what percentage of the bikes out there that pertains to. As it currently stands though, according to the poll it seems like at least 1/3 of people here have damaged a shock in a way that is "not able to be fixed with oil & seals". Whether that means you also needed a new damper body due to some wear/scoring from dirt ingress, or you snapped a shaft/eyelet, or broke a shim inside has not been specified by that.

 My FOX RP3 got "suck down" if i put 300 psi in it i got 1 inch of travel. Used it that way for 2 years.

Fork angle gave ton of confidence, was like riding a hardtail but with a touch of smooth.

 I’ve had this happen twice on a Marzocchi bomber coil shock. Complete loss of damping, oil everywhere. The shock was warrantied for a separate issue by my LBS, then blew up after about 6 months of riding. Got it rebuilt and it blew up again 2 months later. Never buying another one of those.

 I don't always break shocks, but when I do, I'm hucking to flat with 50% sag.

 I think it has to be considered along side the service interval. If a shock spilled its guts within a few months of being new, yes it’s failed shock. If the same happens after 3 years of not being serviced, then I would expect that to some extent, due to seal wear?
  • 3 0
 @RoboDuck: Yep same thing here on DPX2. Under warranty, seems the shims break letting air into the oil or something.

 @freestyIAM: I had the problem with a stuck down monarch a few times too. I just sat down on the tire and pushed up on the extended seat so that the positive and negative chamber can equalize again. The shock then worked just fine, can really recommend to try this as a trailside fix.

As for the poll: I think its more about the influence of frame flex and trunnion, so i dont see a stuck down shock or oil spill etc as a failure. It is very hard to tell where the problem lies with issues like these. It can always be something wrong with the shock manufacturing, maintenance etc.
Only with a catastrophic falure like a broken shock as in the pictures you can really be sure it had at least something to do with the side loading. I definetly dont see a stuck down shock as a failure. I also had a shock show significant wear on the stanchion, but i am not sure it was because of the linkage, could have just been to much dirt ingress and not enough service or something like that

It doesnt really matter though, to really prove the effects of flex you would have to do a big study comparing different frames and mounting options. I guess then you could also include all kinds of failure as manufacturing and maintenance could be neglected with a big sample group and the only other variable being the frame/mounting and maybe riding style

 I hear what you are saying, but if you abide by the recommended service intervals, this sort of "failure" rarely happens. Most people neglect their suspension or just do a lowers/ air can service and then complain when their damper fails claiming "I just serviced it" ... (I have serviced suspension professionally for the past decade). I have customers that do full rebuilds twice a year because they ride 5+ days a week all year long and just flog the shit out their bikes (500hrs or so ride time in a year). Low and behold they never have "failures" because I catch things that are wearing out and replace them before it is an issue. Most people would not wonder why their engine failed if they only did an oil change every 20k miles.

 @shred-harder: No kidding! Were you undersprung or sending it super hard? I’ve been thinking about getting a Bomber shock for park duties

 Exactly. If it interrupts your ride it’s a failure. Irrespective of how trivially it can be fixed.
  • 1 0
 And doubly so when the only way it can be fixed is a visit to an authorized repair center. (looking at you Cane Creek)
  • 1 0
 The reason that's hard to count is that it can be caused by a lack of maintenance. In fact it is *usually* caused by a lack of maintenance. It's kind of like blaming Toyota when your engine fails because you change the oil every 40,000 miles. The engine failed, yes, but only because you did as an owner.
  • 3 0
 @WaterBear: @willdabeast410 of course an old unserviced shock is more likely to fail, but it's still a failure. I'm not saying its a common occurrence (for me, only once, and I do happen to mostly take care of my suspension). While service intervals are important, 50 hours is an unrealistic expectation - especially if you don't live in a place with sloppy, component-ruining conditions. A lot of us on here would be having to do lowers/air can service every 2 months, which simply isn't going to happen. I would feel justified blaming SRAM or Fox if my shock blew after 100 hours since it's last seal replacement.

 Agreed, that’s happened to me. A group night ride in Burke VT. Had my 12yo boy making fun of me for going so slow. I told him my shock didn’t feel right. By ride’s end it was in two pieces!

 I had an obnoxious, repetitive failure where the main shaft seal head on a coil shock wouldn't stay on, so I'd painstakingly rebuild it and bleed the damper just for it to dump all its oil a few rides later. Everything looked good, but the threads must have been damaged or something. It technically just needed a rebuild...twice a month. Such an annoying problem.

 @RoboDuck: really ? DPX2? Never had mine fail. Float X2 on the other hand…
  • 63 0
 I´m working in a suspension service center. Right now the damper that comes in every week with problems is the Fox Float X2. But they can mostly be fixed. In 90% of the time if we can't fix shock it's only because the manufacturer doesn't support it anymore with spare parts. The worst in this are all the "special" dampers like brain or thrushaft.

Regarding the frame design, we also suspect that frames that are too stiff are bad for the shocks because the shocks have to take all the load. One example would be the Pivot Firebird with a Float X2. We had several customers with this combo who all complained about air loss on the trail. No mather how we serviced it, it always came back. They all run different shocks now, mostly coils and have no problems anymore.
  • 13 0
 interesting. i've had to do 2 warranty services on my '21 float x2 in the last year due to progressive air loss (on a meta - which is trunion mounted). not an uncommon issue with this shock, it appears. perhaps poor seal integrity exacerbated by the trunion?
  • 14 0
 @xy9ine: To us it seems like the main seal is just not designed well, so especially in corners the shock is kind of "burping" due to the lateral loads.
  • 5 0
 @IamGroot5482: yer. i was hoping it was a factory defect rather than an inherent design issue. will see how this rebuild holds up; biannual service returns gets a bit old after a while...
  • 6 0
 @xy9ine: If it fails again quite soon you should think about changing it, but if it holds up it´s a great shock. I actually also run a Float X2 and till now (knocking on wood) it works perfectly. It´s just the combo with certain bikes that is just not working well for long.
  • 21 3
 Why would the frame being too stiff be bad? If it's stiff, then the linkages will be moving in consistent lines/arcs, which the shock should like.
  • 13 2
 That’s why I stay clear of any bikes with proprietary shocks like treks or specialized’s. The often 15% on paper claimed “benefits” or marketing bs on these types of shocks claim. True or not. Will never be worthwhile enough to ruin a bike trip due to lack of parts or local service knowledge if something goes wrong or breaks on them.

Also imo, the X2’s are by far the best feeling air shock on the market currently when they’re in tip-top shape. But I always found them to require way more maintenance than other air shocks (even compared to a float X on my other bike) to keep them feeling that way.
  • 11 0
 @justinfoil: Only if thr alignment is 100% accurate
  • 3 1
 @justinfoil: Agreed, this simple statement doesn't seem to make sense.
The stiff frame would only be an issue if the linkages were un-stiff,
thus transmitting all lateral loads into the linkage, and in turn, the shock.
Pivot's upper linkage seems pretty compact/stout.

Maybe the orientation of the FloatX2 in the frame (canister down)
is preventing relubration of the seal, and thus early failure?

Also, sidenote, I personally feel that 29" wheels put more torque on a frame (and fork for that matter),
due to the larger diameter, and longer chainstays.
Be curious ot know if a model that can be set up in both MX and 29 configurations
sees greater/less wear in one of the setups.

 @blcpdx: Keith Bontrager used.to say you're only as stiff as your flexiest part. The stiffer a frame and rear triangle get, the stiffer the links need to be too. Not sure, but this might be it.

 I’ve had to overhaul my x2 more frequently than I would like. Three times in the last 12 months. This is in contrast to the super deluxe on my bike that sees twice the use, but admittedly milder riding, has been overhauled twice (my maintenance schedule). The spud lux hasn’t dumped its oil without warning like the x2 does.

 I have a 2021 FloatX2 that I rode for 6 months with no problems other than never being able to find a sweet spot on the setup and then put it on a box a year ago after I got DB Kitsuma Coil. I put the float X2 back on a month ago and it was making squishing noises and clearly had a bunch of air in the damper. The piece of shit failed sitting in a box.
  • 8 1
 think of the entire frame, from axle to axle, as a single rod. If you push it in the middle it will flex in a bow shape, with the same bend angle at all points along the rod. If the rod doesn't have uniform stiffness, like mixing carbon triangles with alloy links, especially with dual-short-link designs, then the stiff sections will flex very little but the more compliant links will have a ton more torque on them, flexing a lot. This goes straight into your shock, ESPECIALLY if its a horizontally oriented shock.

This is why flexy frames like the steel Starlling Murmur doesn't actually wear shocks out, even when the frames are poorly aligned (almost as if they were welded up in some bloke's backyard shed).
  • 2 0
 @blcpdx: yeah, I'd think the orientation is a big factor.

It's actually part of the reason usually I hang my bike by the front wheel, or leave it upside down for a bit before a ride if I got lazy and just leaned it in the basement: get some oil up to the top of the fork lowers and shock (although my shock normally sits with the seals down, hanging puts it more vertical)
  • 3 0
 @cjeder: Yeah, I think that's probably true.
Ultimately that force has to go somewhere.
By intentionally increasing the stiffness of each element,
frame/component manufacturers are unintenionally redirecting that load
to the weakest/most sensitive point, which is internals of the shock.
Cars have bushings on the upper and lower shock mounts.
I'm surprised noone is making an aftermarket shock-mount bushing kit
that are some sort of rubber. (please direct me to it if they are)
Enve's recent reduction of their MTB rim profile (and thus rim stiffness)
in the face of competition's (arguabily, naturally) superior ride quality and durability,
could be seen as a nod to the usefulness of targeted flexibility.

 @An-Undocumented-Worker: Oof! Mine did that but after about 20 hours on the trail. It's currently winding its way around the planet for warranty while I've bought a Super Deluxe Coil to run for the several months I expect that to take. I think the coil is probably going to stay on the bike even after the X2 gets back...
  • 6 0
 @blcpdx: increasing a frame's structural stiffness (not the shock mounting rigidity) will almost always reduce the side loads on the shock, because whatever load you put in at the wheel will result in a smaller amount of displacement of the frame, meaning less misalignment of the shock mounts. Certainly increasing stiffness of the frame can increase the forces that the frame itself has to deal with, but that's separate from the shock.

 I killed twelve RS Monarch Plus shocks in two years. I'm actually quite proud of it. I class killed as air loss, damper cavitated or snapping an eyelet. SRAM Tech loved me. Putting a whopping great yoke on a horizontally mounted shock of a horst link frame with no seatstay bridge was asking for trouble. Don't have to service it if it blows up before the service interval. Win.

 @dancingwithmyself: Anybody with any knowledge of suspension does.

But there are a whole lot of people who just want to get on their bike and go ride it, and have no idea what caused their shock to break, they just know that they got on their bike and their shock broke.

And suspension mfg's have to be super careful with wording when explaining it to people (and generally opt to dance around the issue), because the last thing they want to do is piss off their OEM customers by telling somebody who's shock just broke that "it's your bike companies fault because they made a poorly aligned frame, take it up with them."

 "Clevis links increase the leverage over the shock, meaning a given lateral force is more likely to cause the shock to buckle or bind, making it unable to absorb bumps, or leading to the shock wearing out or even breaking."

This isn't precisely what we're saying - it's not lateral force or lateral misalignment that causes issues with clevises, it's just that the eye to eye length is so much longer for no increase in bending rigidity that they are inherently less able to resist buckling. Get a 30cm/1ft metal ruler and compress it lengthways between your two hands and watch it buckle easily. Cut a 5cm/2" segment and try the same with that piece and see if you can get it to buckle.
  • 2 3
 I somewhat disagree. Disregarding the stupid Specialized bolt on design, yokes attach by rotating the shock eyelet 90 degrees. This allows for "yaw" pivot motion, and the yoke link is mounted 90 degrees to this, allowing for "pitch" pivot motion. This effectively isolates much of the "bending" the shock would normally experience in, say, the old Specialized design that was bolted directly into the shock body.
  • 1 0
 @hamncheez: Not all shocks are like this, unfortunately. Some 2017-2018 Specialized frames I’ve ridden had the yoke rigidly mounted to the end of the shock, with no allowable play.

 @hamncheez: if the shock can pivot part way along its length (especially while both ends are held rigidly in that plane), that will by definition introduce buckling because now the shock is no longer aligned properly as a compression column - it is not at all equivalent to a spherical bearing for example. However, I don't believe that there is typically any significant "yaw" pivot motion as you describe it - the buckling mode described here is actually in the vertical plane (ie looking from the side of the bike, not the top), not from side loading itself. The mode of failure I am suggesting is due to a reduction in the ratio of polar moment of inertia (shock's resistance to buckling in compression) vs column length (eye to eye length). The frame could be perfectly aligned and not flex whatsoever laterally, and this mode would still exist. It could be the case that the Specialized yokes were actually better in this regard (the anecdotal evidence seems to suggest otherwise though) because the interface between the yoke and shock was much more rigid and harder to introduce buckling (vertical misalignment) in, while the angular misalignment laterally is reduced with a yoke due to the increased length.
  • 2 0
 @VorsprungSuspension: I wonder if it is more modern shock design rather than the frames that are the issue. I had a 2011 Enduro with a FoxRP23 on it. I never bothered to service the shock in the 2.5 years i owned the bike (the frame cracked at the BB eventually) and the shock never failed. An old XC bike with a Fox Float I hammered with bent shock bolts regularly never gave a problem either. Were these older units built more robustly than newer shocks?
Bring on the 2018 Enduro and after 2 years or so, the Monarch Plus failed internally with a tiny crack in the adonized damper shaft. No warranty and no spares available from SRAM. I now have a second hand Ohlins STx22 - also a problematic shock but since a service has been great. It has a steel damper shaft and I suspect this won't develop a crack like the Monarch Plus. It may leak some air again, but at least its serviceable.
  • 2 0
 @headshot: I actually had one of those Enduros too, and while I didn't have the same good luck with the shock you did (mine lasted about 4 months), with that particular bike they put the yoke on the more robust (to bending) end of the shock.

 I had 4 trunnion mounted shock failures in the last year. 3 shock failures on a 2020 enduro on a dhx2 and float dhx2. 1 shock failure on a transition spire with a super deluxe ultimate. Before getting a bike with trunnion mounted shock I haven't had a shock failure in years.

 So you're convinced it's because of the trunnion design and not because of Fox & Rockshox's crappy QC?

 This is a silly survey. Are we talking structural failures? Or hydraulic/damping performance failures? Two TOTALLY separate topics, and both are common.

Edit: Serving a damper/air can rarely would have anything to do with a structural failure of an eyelet or body either. Pretty much irrelevant.

 Disagree: if you have to send a shock in for warranty service/replacement due to failure during intended use, it is a Failure, Capital F. Particularly with Fox shocks require nitro charges after damper service, a damper failure is beyond the reach of 99.9% of riders and even most local shops. There are 20 LBSs within a 45min drive of me, but not one has a Nitro tank, much less a mechanic they let work on dampers: they all mail them off to a specialty suspension service.

Also, thanks for update on Fox: my two damper failures were on older versions of the Float CTD, which required Nitro. Don't you need a shock pump that goes to like 400psi to recharge a shock with air though? Afraid mine only goes to 250psi.

 @powturn: the ones I've seen that use plain air need much less pressure. I think 120ish in newer Foxes, and I think 250 psi was the max on a Monarch Deluxe, so totally within normal shock pump range.

 Yes... repeatedly.

2019 Stumpjumper Comp Alloy. Jacked the DPS at least twice. Fox said they'd never seen some of the damage on the internals like I'd done. Then I decided to go with a coil, so I got a Marz CR coil. I blew up two of those before Fox decided that the CR and the Stumpy don't agree with each other and asked if I would take a Factory DPX2 instead as a replacement fo the Bomber CR. I agree and I've been happy with that shock ever since.

I've also had multiple issues with my fork when it was a 34, but since I upgraded to a 36, it's been all good.

Might be time to lose some weight.

 I broke a Push 11.6 at the shaft when a stray rock the size of a fist kicked up into my GG The Smash frame and somehow got tangled up with the spring.

 Here is what Marzocchi says at least for coil shocks:
www.ridefox.com/fox17/help.php?m=bike&id=1138

They're not too specific but lateral force seems to be an issue.

And what can potentially break a coil shock might lead to extra wear in an air shock. The Monarch (+) seemed to have some issues at least.
  • 7 1
 Honourable mention to the Pole Evolink 158 that would sideload the RS Super Deluxe so much with all its incredible rear end flex (it's compliance brah) that the shock was scored inside and out so deeply that half the internals needed to be replaced. The local RS techs couldn't believe that a shock with this much wear came off a bike that was two months old and ostensibly in as-new working order. Imagine their surprise when I was back less than a month later with all the same issues.

 You can't fit a Super Deluxe to a Evolink 158. I have been riding mine for multiple seasons with a Monarch+ and Vivid Air without problems.
  • 6 0
 EVOLINK 158 is not compatible with metric shocks. If you shortened the eye to eye, that might encounter over-rotation of the links. If the shock is longer, the shock might be in the wrong position at the beginning of the stroke. However, the frame might have a misalignment issue as well. Either bent frame, or directly from factory. Please send more info to our customer service or our Pole Bicycle Riders Group on Facebook. EVOLINK does not have any of those issues that t Steve mentioned in the video. EVOLINK has the traditional shock setup without any shock extenders. It's made with standard bushings.

 Get a Bomber coil CR they said, simple and reliable. It’s just gone back for the third time in a year for a knocking damper. I was riding up hill when it went last time.
Glad I didn’t sell the X2 that came with my Rune.
  • 5 0
 That's a feature, not a problem. The wave spring (039-00-167) under the compression valve breaks, the compression valve can then move freely inside the reservoir when the shock changes direction and you feel that as a knock. This has been happening ever since the days of the Fox Van RC (your Bomber is just a re-stickered one) and will continue happening until Fox addresses the design.

 I broke a rockshox coil with du bushings so I am not sure the data is really related to the article, the question is too broad

but to be clear the R3ACT suspension (polygon/marin) really really sideloaded the crap out of shocks.

with trunnion shocks it will be the frame manufacturers design responsibility to limit the flex at the shock (which is normally very close to the seat tube pivots anyhow).

Forget about sideloading causing failure, it also increases friction and stiction and will make the bike harsh. Its a lose lose for a bike to sideload the shocks and if a frame manufacturer overlooks it; the bike will be a poor performer.

 Fox Float X2 shock brand new in 2018 (MY2019); 185x55 trunion mount on a 135mm travel bike.. At 13 months, the air shaft/seal had failed, most of the damper seals had failed, and the stanchion had cracked at it's threads. Fox basically told me, "well, you're 1-month out of warranty, so tough shit". Ended up being a $350 repair.

I will never buy a Fox product again.

 Scott Ransom E-Ride, fox x2 trunnion shock. Significant wear marks at all the pivots from either poor design or the frame is flexing under load. Shock has heavy wear internally after 45h of use. Apparently the bike is fit for purpose according to the shop and Scott, I'd counter that given the evidence presented and their lack of replies to the issue.
  • 5 4
 Scott is the worst. I will never buy another Scott bike again. Their design is shit. They think it's cool to use bolt heads that aren't Allen key compatible which makes you spend more money on one specific bike brand hex key and for which there are no other discernible benefits to owning, and their proprietary nude shock is the most blatant money grab for services from fox factory only. I sincerely hope Scott goes out of business so no one has to deal with their shitty bikes anymore.

 @ryd-or-die: It's called Torx. Even the cheapest multitool I own (which came with a Polygon hybrid) has the right sized Torx driver for any trailside adjustments to a Scott.

 I had a 2018 Stumpjumper with a bad shock. It stopped holding pressure about two weeks after I bought the bike.

 In 2019 I had the main seal on the positive air chamber of my Float DPS fail. I'll consider this a failure as my LBS (which is a Fox service center) couldn't fix it and it had to be sent to Fox under warranty. I also had a Fox Float get stuck down way back in '07 or '08. The seal between the negative and positive chamber failed. Luckily that was on a demo bike so I just handed it back to the shop & forgot about it.

 My 2018 Jeffsy ate the shock due to what YT called "rear triangle misalignment'. They tried to claim it could only be due to me landing lots of large whips sideways which, whilst flattering, is not the case!

Luckily for me they were forthcoming on warranty and honestly a pleasure to work with to get the issue resolved; a new frame and shock and i did the rebuild myself.

 Popular enduro bike, 2017 model year with a yoke. 100% failure rate across maybe ten bikes sold through the shop I worked at the time. Most people went through at least a couple of shocks. Mix of air springs sucking down and dampers blowing due to flex. If you raised a fuss after the second or third they'd just send you a coil which seemed to hold up much better. In all fairness the bike brand sorted it out every time, but the manufacturer of the shock started refusing warranties as they knew it was an issue with this particular frame. One guy went through six shocks if I remember correctly! Couldn't just fit any old shock to it too as they had a proprietary shock eyelet that limited you to only a few options. And maybe giving a little too much away, but another proprietary feature that introduced a few extra seals to the air can definitely compounded the problem.
Said brand quickly ditched all the proprietary crap, thankfully! I've avoided yokes ever since, but never had an issue with trunnion shocks!

 I dunno. On my '16 Stumpy I rode about 20x the service interval until I for some reason decided to have the Fox shock serviced. Three rides later it turned into a spring. New service, and it lasted for about a year of abuse before the same thing happened. LBS mentioned that there were occasions where service kits were of poor quality, but it was hard to discover. I've been lazy with servicing since, about once a year. And it's never happened again. Got a '19 Stumpy CC, and that shock puked all it's oil after about 4 months, which was common AFAIK. Sold the bike. Never had it happen on any other bikes, though, but I have gotten 6 or 7 RS forks replaced under warranty over the last 8 years.

 @Compositepro: on the surface of it yes, but it depends also on wall thickness and ID/OD measurements-so structural rigidity is not necessarily down to purely the amount of metal used, but moreover how it is used. If the solution to strength was solely the amount of metal used then we'd have a lot of heavy components. From my own personal experience of failure and my knowledge as an engineer it seems larger shaft diameters are beneficial for other reasons such as providing a better connection at the eyelet where play often develops.

 How does a stuck-down shock fit into this? I had a CC DBair IL get stuck down on my '19 Stumpy LT after 1/2 ride.

 Great and informative video. Let's also take into consideration the lack of full serviceability of modern shocks. I had the rebound fail on one. When I finally dug out information on servicing it, and looking beyond the special tools needed, I got to the part where it needed to be recharged with nitrogen and gave up. The service took two weeks and cost over $200! A replacement "spare" was going to run me close to $600.

 I've killed two monarchs and a (recalled) dbair il on my clevis linkage process 134, and I killed a dpx2 on a 2019 stumpy Evo which is also clevis. Dpx2 and monarchs we're scoring on the damper shaft, dbair il the damper shaft snapped at the head which is what they were recalled for and I got a replacement free no problem. I can believe that the problems I had cash be chalked up to side loading with the clevis. I have a trunnion float X2 on a 2020 Enduro at the moment, we'll see how long that lasts.

 Servicing Gen 1 Processes with the clevis link and old enduros the side loading would pit out the internal damper rod making even a full service useless. That's an expensive fix no one wanted to cover under warranty. I'll never buy a clevis link bike. I think these full-on structural failures are from not running enough spring rate or a impact that would kill any shock though.

 You could've also asked about obtaining parts to fix broken shocks. I recently sent a Fox X2 away for service as it had become squelchy. My fault for leaving it too long between services but it turns out the air can and damper rod needed replacing due to scoring. Presumably a bit of grit had entered the shock. The air can isn't available for 3-4 months and the update kit that would've also done the job isn't available either, and no idea when it will be. End result is I bought a new shock from another manufacturer. Goodbye Fox.

 Not sure if this has been mentioned but so many of the bush pins in Rockshox eyelets are so stiff and hard to rotate that I'm sure this is compounding the issue of some shock failiers as its not allowing the shock to pivot around its mounting axis as its meant to do ! Just my 2cents.

Ruben Torenbeek will happily tell you what he thinks about Trunnion…
I mean, when bike designers hate it and know it sucks. But still kinda forced to use it. Bad situation.

 The last shock I killed was a Double Barrel Air that the service center had botched the rebuild on. Other than that I'm blessed by the suspension gods. I've blown my fair share of Rock Shox fork dampers though.

 My old Cane Creek DB Air was the worst thing I ever put on a bike. Every 10 rides it needed to be re-built and yes I was using a professional shop to do it as well.

 Rock Shocks rear shock on my gen 1 Hightower can't handle park days. It gets too hot then the seal on the inside slips off and the dampener goes down but not back up. After it happened a second time I bought a coil.

 Once had a Progressive 5th Element Shock fail on me on my old Santa Cruz Bullit (no, not the ebike monstrosity that they now claim is a Bullit). To be fair though I cased a huge jump on it and Progressive stepped up no questions asked to replace it.

 Seriously, people should consider a hardtail. Modern hardtails are so much better than say, 10 years ago. Decent tubeless tyres for puncture resistance, 1X drivetrains so you don’t constantly throw the chain and near DH bike geometry means you can get away with so much. Not for full on downhill duties but day to day trail rides you can do a surprising amount with a fraction of the maintenance. It’s not uncommon for riders to have several bikes, so make one of them a hardtail. Fully rigid though, might be a bit too far!

 Never because if I ride more I service it more. Why be stuck in the middle of nowhere because of piss poor attention to your kit?

Same with cars. Some people literally don't touch their cars. Madness.

 My 2020 Scott Gambler has been through 6 warrantied Van RC before being upgraded to a 2021 DHX2, that all be it lasted longer, but has since failed in the same way. Trunnion mounted.

 The one downside with trunnion shocks though is that the repair is much more expensive if your shock bolt threads get damaged!

  • 2 0
 @Beaconbike: wow thanks for the suggestion I will check this
  • 2 0
 @Dogl0rd: If my air sprung fork ever doesn't hold air, this is the reason. Not too often, maybe every few months or so. In my case it could be because the shockpump I use requires me to twist a part that drives the valve core pin in (to open the valve). Maybe those who use a pump that works with a lever to do that don't have this issue. Not too much of an issue for me, just something to check every now and then.
  • 2 0
 @vinay: I think you are right!! I'm grateful for the responses to my post! The core tightened down a bit when I turned it. This may have saved me a trip to the shop and a week without my bike. I am pretty decent at working on my fork, but I've had trouble getting shocks open, so I usually just bring it to the shop. Will test it with a ride this week. Great advice Smile

 This is kinda hilarious, as two days ago my rear air shock's o-rings let the air past after a massive 3' to flat.......When it did that, I kinda stared at it and realized my new bike was already 3 years old....I'd kinda forgot all about it....New seal kit on order! Shocks are very reliable these days, even when you neglect them for years. Amazing

 @VorsprungSuspension would putting a slightly compressible rubber or plastic washer between the rocker and mounting point of a trunnion shock help the issue?
  • 2 0
 Unfortunately not, it would prevent the bolts doing up properly if it was compressible, as the shock needs to be clamped hard up against the bearings in the rocker.

 2014 Spez Enduro 29 is notorious for destroying the original spec cane creak inlines and double barrel, the shock flexes both laterally due to side loading and vertically in the middle due to the compression path and the clevis.
