RockShox Revamps Reverb Dropper Post

Mar 15, 2016
by Mike Kazimer  
Picture a dropper post, and the RockShox Reverb is probably one of the first images that comes to mind. It's one of the most commonly spec'd dropper posts on the market, appearing on everything from mid-level trail bikes all the way to exotic dream machines. The post has seen a few slight revisions since its introduction in 2010, but it recently received a complete internal reworking in order to increase its reliability, and to allow for the addition of a 170mm travel option.

What's different about the new version? Externally the post remains relatively unchanged, but according to SRAM, "all the smallest details, down to the single seal, have been re-evaluated and updated to pass the hardest and longest durability tests." That includes a new internal floating piston designed in conjunction with SKF, and increased bushing overlap, which should help to keep the post operating smoothly in adverse conditions. Like the previous iteration, the post's return speed can still be adjusted at the remote, but the new internals have allowed the maximum return speed to be increased, providing a more usable range of speed options.
Reverb dropper

The addition of a version of the Reverb Stealth with 170mm of drop is going to be welcome news for many riders, especially those on the taller side of the spectrum. It's foreseeable that the increased drop will allow companies to create frames where the top tube height and standover clearance aren't much different from size to size; taller riders will be able to use posts with 170 or 150mm of drop, while smaller frames (and riders) would use a post with 125mm of drop. Until now, posts with more than 150mm of drop had only been offered by smaller companies, which made them more of an aftermarket accessory rather than something you'd see offered on a complete bike. SRAM's entry changes this, and we'll likely be seeing the 170mm post appearing on larger frame sizes in the near future.

The new version of the Reverb (top) has updated seals, and a new IFP (the blue part on the top right) designed by SKF.

 Will it be possible to gutt my current post, when/if it fails with the new components?
Or was there seen to be no need for interchangeability between revised parts?
In my industry, we dont call new designs, revisions, unless they will work with the old parts in a given assy.
I feel like MTB industry does not live by this philosophy, which is why i have to ask...

 @zion-i, you won't be able to put the guts from the new post in your old Reverb, but RockShox has no plans to stop offering replacement parts for older Reverbs.
  • 17 2
 So @zion-i is right. This is a new model, probable upgrade, but not a revision.

@nutelladonut, I would love to have 150mm or 170mm of drop but it's only offered on the internal routed version. This makes all these new posts incompatible with my one year old frame unless I roll the dice and drill the base of the seat tube myself and hope my carbon frame never needs any warranty claims.

 Hey Nutelladonut. I drilled a stealth routing hole in the bottom of the seat tube in a SC Tall boy LTc a couple of years ago. I actually called up SC, and someone talked me through the procedure, as well they sent me the grommet that fits in there. Hole was 12mm tall by 7mm wide, I used a pilot bit then used a bigger bit and dremeled out the rest. The SC contact said it would not void the warranty unless there was an issue at that spot. They also said that was pretty well the same procedure they used. And.....to top it all off, the frame now has a warranty issue elsewhere, after 4 years of riding, and its been replaced by the new Hightower, since the TBc is no longer available. Dam good warranty I'd say. Drill away with confidence.

 Rock shox are not wrong.... Revision is used differently by different companies. Some use new part numbers. Some use new SKU's. Some use issue and revision. Some use all the above depending on the change. We could no doubt go into who tracks what and what constitutes a revision change or not. But it's open to the discretion of the company, often through collaboration of various functions.... etc etc

 I'm sorry but I'm going on multiple rebuilds and know way too many people with reverb issues. The original design had been rushed to market. Even with the new internals it still is all hydraulic. With 9.8, Easton and race face droppers on the market there is absolutely zero need to buy a reverb. Those droppers are next level compared to the new reverb.
  • 2 0
 9.8,,,yes, when you can get one and I would prefer the 175 9.8 if I could get one...

RF/Easton...have you read the reviews? same design as 9.8 but not the build quality...and they aren't doing 170 (175 for 9.Cool

I have had several reverbs and they have not been perfect but they do have a tough life....servicing is a fair enough requirement and most the time a quick bleed does the trick...

 The 2016 RockShox spare parts catalog lists full service kits for 2010-2012 and 2013-2016 Reverbs (FS1, FS2, and FS3) that includes the new IFP, so perhaps this suggests a backwards compatibility.

 @theDude403

They bought a new IFP to the market for current model year reverbs late last year. Its basically the same as the current one minus the glide rings and is made from plastic rather than alloy.

It is not the SKF one fitted the the new post.

 Why didn't they take this opportunity to redesign the remote? I don't think I need 170mm but I could have used a more comfortable way to actuate. They could have shortened the throw or turned it into a lever or trigger instead of the push button pen style.
  • 8 3
 Could be legal restrictions or patents on designs that they can't use.

 Other way round for me... 170mm drop will be amazing since I'm so lanky, but get on really well the button mounted under the left bar, so win win. Yay for me!

 Amen Bigtim! I feel your oversized pain! 170mm will make a big difference.
  • 2 0
 @bigtim - I'm with you. I had a Revert on my old bike, which got stolen. Loved the left side under the bar push button. My new bike has a very low top tube and a 150mm Lev Integra. I love being able to get lower while being centered over the bike (that wasn't possible on my old bike, which had a much taller standover). And I have enough space to accommodate an extra 20 mm of travel now - so going to this over my current post might be tempting.
  • 9 1
 When everybody and their dog uses shifter mimicking cable actuators, I doubt any of them could sue Sram for a more ergonomic actuator/button/lever.
I've worked in sporting goods manufacturing for much of my career - a rock climbing and ski company and a certain expensive carbon rim maker. There is an attitude of: if we do it different, it's because our way is superior to others, and you better have brand loyalty for the brand you work for. Try telling the head of R&D that their button style actuators should be redesigned to something better and see how long it takes until you're the guy who cleans the toilets around the shop!!
  • 5 0
 I am with McMurray - simple redesign of the remote would have been great.If it was narrower and/or had the ability to be adjusted vertically and inward / outward it would make a huge difference. Now your only choice is inboard / outboard of your brakes.
  • 3 1
 Agreed that a re-design of the remote would have been a lot better since they can offer that separately for those of us that have the old version of the Reverb. I definitely prefer hydraulic actuation over feeling like a sloppy cable actuated cable of other brands though.

 Of course you could just spend even more money and get one of these levers...

 @ChampionP You nailed it, i think that mentality does exist in A LOT more company's then we would like to admit these days. I want to think these are the ones that will be bankrupt and out of business by the end of the decade, and the ones with open minds will have their opportunity.

 Totally agree. If a plunger button was a good solution for handlebar controls, that's what shifters would look like. After decades of evolution, shifters are quite obviously the best handlebar control. Droppers tried to reinvent the wheel and failed.

 Is there really that big of difference between dropper post button options? I mean, everyone has their preference.... I just don't see the point in getting nitpicky when it comes to the button style. Go out and ride, don't sweat the small stuff.
  • 4 0
 I can't say for sure that's an industry wide attitude, but that's been my experience. Most people don't like to believe that they can be wrong. I mean look at ellesworth linkage - that won't change until Mr ellesworth leaves the company, regardless of how badly it affects the company.
  • 2 0
 I would have preferred a shifter style remote option to be offered in addition to the longer travel and hopefully better reliability. The longer bushings should be an improvement.

The button, when mounted underneath, is not bad though. I can't believe some 1x bikes that come with a Reverb, actually have the left hand button mounted on top. I mean, if it's a 2x bike, sure, there's no other option, but if it's a 1x, damn, get the correct remote. I just demoed a Trek with that this weekend, and I was thinking "wtf, is your product manager a f*cking idiot?"
  • 2 0
 Actually like their button the most, I run the right hand remote on the left side underneath the bar and I have found it to be the most ergonomic even compared to the south paw and I can actuate the reverb in this location the fastest and I like how smooth the button is. Just installed a 170 last night and came from a 150 ks after my stock reverb blew out in 6 months. It barely worked on my large tracer T275c, I say barely because the post is very long to accommodate the 170mm travel and their collar is significantly bigger than the ks design so luckily even with about 25mm or so of exposed seat with my old ks 150 lev I was able to run this post all the way slammed and end up with the same seat height. I wanted to comment about that incase someone is in the same boat as me. im 6'1" with about a 32" inseam. Also I would like to add that the install went very smooth, I was able to borrow the line cutter tool to shorten the line and after putting the remote in the fastest setting the thing comes back up insanely fast, also I didn't need to bleed the system either when I was done which seems crazy but I was able to use that red threaded piece that is included to close the line up and I kept the remote from losing fluid and didn't push the button while it was off.

 @vernonjeff your office chair mechanism probably weighs 4x as much as a typical dropper post and is designed to operate in a clean, climate controlled environment with less side loading. That's a little different from something designed to be used outdoors on dirt that needs to be as light as possible.

 I got tired of constantly fixing my Reverb. Getting a fresh rebuild right before a 10 day trip last year and having it die 7 days into the trip, mid-ride 20 miles away from the trailhead was the last straw. I wouldn't run another one regardless of the new improvements.

 Typical mountain bike marketing; why even bother to give the weight for the 100mm travel 30.9mm seat post which is possibly bought in the smallest numbers. Please publish "30.9 x 125 mm with remote" and "31.6 x 150mm with remote" weights as that is what most riders will be buying and might be considering against another brand. Also what about low temperature use as that is a well known common area of failure for the seals?

 Gravity usually has the drop mechanism sorted.

 Find me a dropper post that goes down with gravity and I'll buy one for each bike. They all require you to sit to depress them... which is completely counter intuitive to what you should be doing as you come up on a tech section or are about to drop into something steep. Sitting ruins flow. Current droppers are built for riders who grind it up for long periods and then descend. I'd like to see one for those of us who ride frequent ups and downs...

 If it "dropped" down, how do you suppose you get it back up? Theoretically when the seat is up you are seated, so all you are doing is lowering your weight then standing up
  • 1 0
 Not wanting to drop your dropper post by sitting down on it is indeed a First World Problem. If some people don't want to take such effort why would they toss crap on e-bikes?! How lazy can you really be? #pussygeneration
  • 1 1
 it isn't about effort or laziness, it's about practical design that suits the true need.

Where we ride the hills are rolling, so you're up and down like a yo-yo on any given ride. So just as you crest a climb and are about to start a short descent where you want the seat out of the way most times the rider is changing from a standing climb position to a sit only to drop the post, then you're back up to descend. Kills flow.

May not be an issue where you ride, but for the vast number of riders who don't actually ride in mountains it is a functional issue with current dropper designs that has become apparent as bikes become more capable at climbing and descending.

And if I knew the design solution, I'd build one. There may not be a practical design solution. But if someone comes up with one, I'll buy one for every trail bike in the stable.

PS - internet trolls are the worlds biggest first world pussies Wink

 Seems to be true!! I have a Reverb on both bikes and they have both been replaced under warranty once. Only one (on the older bike has) reached time for a service! The Pikes on the big bike have been warrantied twice, once for the creaking CSU (new complete fork) and once for a faulty damper (new internals). Dunno why I always buy RS stuff TBH!

 Annoying the 150/170mm travel isn't available in non-stealth. Not everyone has internal routing on their frames. I understand there may be an issue with the length of the hose required however for me, the 125mm drop just isn't enough. I like to have a frame which is low and long but it does mean for the climbs the seat needs to be quite high. Then on te downs it needs to be low otherwise it hits my legs.

Might just have to drill a hole in my frame...
  • 7 1
 FYI, people have reported severe problems after drilling holes. I would strongly advise you against doing so. drilling introduces microfractures because the frame has been hardened, which then lead to full on cracks propagating through your frame. We don't hear about it so much in MTB, but the commuter & touring market talks about this stuff all the time.

It basically comes down to: when they're fabricating the frame, they can drill before hardening, and stealth dropper routes are almost always reinforced even then(take a look at damn near any aluminum frame with a hole in the seatpost on the market: it'll have something resembling a washer surrounding the hole.) You can't easily do either after the frame is finished, so consider how much a cracked seat tube would suck.

I suggest a LEV. 150mm without internal routing is available.
  • 1 0
 Yeah, I found the stealth routing to be more trouble than it was worth.
  • 1 4
 I'd drill a stealth routing hole in my AL or carbon frames without hesitation. It's just a pass through hole and nothing is being mounted to the bike via the whole so it's not going to spontaneously crack. See the post above by Pedaller where SC provided instructions on how to drill his frame. There is nothing to worry about.
  • 3 1
 Not true. Drilling and careful filing is very unlikely to cause 'microfractures'. If the hole is not too close to the weld an nicely radiused it should be fine. I just checked my Knolly warden and it does not have any reinforcement around the hole for the dropper cable. I would definitely drill my frame.
  • 2 0
 I couldn't imagine a non-stealth cable on the outside of a bike that will be moving up and down 170mm
  • 2 0
 Ummm, there are several seatposts where the seat end of the cable doesn't move the entire length of the travel.
  • 4 1
 @Skooks SC told him to drill a CARBON frame. Contrasted by when I asked another manufacturer about an ALUMINUM frame, where they told me specifically about the cracking problems, that you shouldn't do anything like this to HARDENED ALUMINUM specifically(go ask any metallurgist whether drilling hardened, brittle metals is a good idea) & pointed out to me where other people have had frames destroyed by drilling a tiny screw hole to mount a fender, & that's only riding on the road.

But yea, I'm sure all those people were lying, based on you declaring it "not true." Whew, glad that's over. fire up your drills
  • 5 0
 You almost never machine aluminum in O-temper. It is too soft and gums up your tooling and you would get shit for dimensional accuracy. After aluminum is formed, you run solution (T4) then overage heat treat (T6 or T73 or whatever HT you want). Then you machine it. Every bike part on your bike is machined into what you call "Hardened Aluminum". Of course it is possible to get cracks when you drill a hole in your frame, that creates a stress concentration and weakens your tube.
  • 1 1
 I stand corrected. Though I'm sure you'll agree there's a lot more done when putting a hole in a frame during construction than taking a hand drill to it.

I still stand by the fact that if you do some research, people's results with drilling holes in their frames have had some pretty spectacular failures, & it's not exactly uncommon either. unless, like @jefe , you have professional experience, & know how to avoid the issues drilling a frame creates, don't do it. This isn't putting up a picture on your wall. Buy a LEV or a new frame.

 For what its worth, here is my description of the first basically simple Wink design:

Rockshox Reverb

Many of the components are structural and do not interact with either oil nor air. The components operating with oil and air are described within. The chief components controlling the operation of the Reverb sliding seat post include:
IPF Tube, Item 8, Internal Floating Piston Tube

IPF, Internal Floating Piston, separates oil from air. Oil on top, air on the bottom.

Reverb upper assembly, Item 6, popit valve controls flow of oil between two volumes, Volume 1: Inside of IFP tube, Volume 2: volume between the outside of IFP tube and upper tube.

Inner Seal head, the inside O rings trap air against the main piston. The outside O rings provide mechanical support. The inner seal head screws into the IPF tube.


Main Piston Shaft MPS, Item 11.
The main piston shaft MPS, The bottom of the MPS has a Schrader air valve assembly screwed into which 250 psi of air pressurizes the inside of the MPS. The air valve assembly is affixed to the bottom of the lower/outer tube using an inside circlip. The lower/outer tube is in turn fixed to the bike frame. The MPS moves in unison with the lower/outer tube creating the sliding action of the seatpost assembly, this sliding is governed by the sliding action of the MPS inside of the IFP tube. The MPS contains a piston configuration at the top with O rings and slip rings. This O ring keeps oil above the main piston shaft and pressurized air below. Air passages at the top of the MPS allow the pressurized air volume to reach the inside of the IFP tube. Air passages at the bottom of the IFP tube allow the pressurized air to reach the outside of the IFP tube, that volume below the Internal floating piston This volume is limited by the position of the IFP piston. The volume below the IFP is charged with air. The volume above the IFP contains oil.

The oil volume remains constant and is shared between the IFP tube and the volume between the out side of the IFP tube and the upper assembly. Remember the main piston shaft, its position determines not only seat height, but also the volume of oil at the top of the IFP tube. The remaining oil sits outside of the IFP tube. The poppet valve controls the flow of oil between these two areas. The poppet valve when depressed allows oil to flow.

When seat is lowered: Poppet valve is pressed in, rider applies force on top of seat. Main piston shaft moves upward, pushing oil from IFP tube to the volume outside of IFP. IFP, the floating piston moves downward to allow this increase in outside oil. This compresses the air below the IPT piston. The 250 initial PSI is now in excess of 300, to top of my gauge.

When seat is raised, poppet valve is pressed into top assembly, allowing oil to flow. In this case the rider applies no force to seat. The compressed air pushes the IFP piston upward. This increases the air volume below the IFP, the oil outside the IFP tube crosses over to the inside of the IFP tube. This in turn pushes the main piston shaft downward which raises the seat.

What to do when your seat post loses air: What seals are responsible for keeping air inside the post? Only a few O rings actually keep the air inside the post. The inside O rings of the Inner Seal head are very important. There are 2, one round, one square that trap air between the main piston and the IFP tube. The bottom of the main piston is screwed into a Schrader valve assembly. This assembly includes an O ring that is screwed into the main piston shaft. The potential for air leak at this location must be considered. Ideally the interface between the main piston tube and the Schrader assembly would be a finer pitch screw thread, high tolerance diameters and multiple O ring seals. I enhanced the current design by simply cutting a rubber washer for the main piston shaft to press against the Schrader assembly. Others have used thread sealant and loctite.

 The part number for the SKF IFP piston (blue one) is 11.6818.034.000. Seen it for sale on eBay.

It can be used for Reverb Stealth and Non-Stealth A1/A2.

 Having quite long legs, the extra travel from the 170 would be a good thing. The 2nd hand market for Stealth Reverbs is in pretty good shape (at least here in France), and if the new Reverb actually releases in a few months, it would still be fine.

And I'm one of these guy that change his stuff just because I feel like changing, not because it has died and is out of warranty Wink

 I would want the new one because of the faster return speed. hopefully buying a new bike in the next few weeks(buy my Titus from buy/sell!) & one of the first things I was looking at swapping from stock on my new steed is the Reverb, because I don't like the remote, the return speed, & was apprehensive about reliability.

If they address the speed & reliability concerns, well, that Novyparts remote is expensive, but it's cheaper than buying a new dropper.

 It's good for some people to have their option. I am personally fine with 100mm drop, keeps me remembering to stay away from hanging on the back. Now that I learned to manual with seat dropped by not more than 5cm from top position (even 29+ bike Wink ) I see no point in going for uber long travels, also because it puts more leverage on bushings. I'd love a 450mm long version with 100mm travel for massive bushing overlap.

 Has anybody drilled a Mondraker Prayer frame? It is pretty burly and designed for freeride, having been sold always with coil and even with double crown forks, so I guess the frame is not exactly weak. I run it with a Marz 55 Air and a Rock Shox Monarch Plus and do basically "enduro" aka mountain biking, no big drops or impacts. I am thinking of drilling a small hole in a similar place as the Canyon Strive, as the frame build is relatlvely similar. I asked Mondraker, but they weren't very helpful, just trotting out the usual "is dangerous for you and the frame" shit. Any advice?

 It is a matchmaker mount. It works with guide brakes but the location of the button isn't great. I plan on switching back to separate mounts just to get the button in a better spot. The button can be put above or below the bars depending on if you buy the left or right sided version. It has to be run above the bars though if you plan on also mounting a shifter. Again, this unfortunately dictates a rather unergonomic button location.

 Completely disagree. My reverb hose has always leaked around the button, and the fluid started corroding the clamps and bars in that area. Hydraulic lines get air bubbles and need to be bled. They also act funny with changes in elevation. It's just way more complicated than it needs to be. Use a cable like everything else!!!
  • 3 0
 @Macropod - In what backwards universe are you living in? There's less to go wrong with cable actuated.

You know what the rebuild for my dropper consists of? Wiping it down, putting like 2cc of oil in it, and replacing a $2 cable. A Reverb rebuild has no joke 40 parts/seals.
  • 2 0
 Couldn't agree with you guys more (skelldify and Alias530). I wish that the new Reverb was cable-actuated. On my Reverb (and just about everyone else I know) the little lever would leak if you looked at it wrong...and was held together by a crappy paperclip-looking thingy. The more moving parts, seals, etc...the more that can go wrong. Keep it cable, is what I say!

 Aaah yes. I remember when bikes had steep head tube angles and skinny bars. We don't need any innovation do we. That stuff was all flawless. To some degree I agree that 170mm is getting excessive. And I would make the same argument for 800mm bars on a trail bike. BUT. You can' say how someone feels comfortable on a bike. If 170mm of seat post drop makes someone more confident out on the trails then that is great, no complaints here. And 170mm dropper posts is something many people have been screaming for for the past year or two.
