PINKBIKE FIELD TEST

7 of the Latest and Greatest Enduro Bikes Get Hucked To Flat

Large Impacts Pending




This is the moment you have all been waiting for. The infamous Huck to Flat. What better way to cap off another Field Test than sending all of the bikes to full bottom out in super slow-motion, right?

We do our absolute best to make sure the wheels hit the ground at the same time and both the fork and shock reaches the maximum compression. That’s not so easy when you have to pedal into a head wind on soft gravel and take off switch-footed!

These burly components and 38mm stanchion forks survived just fine, but you do get a chance to see the suspension fully squish, chains nearly hit the ground, derailleurs flick about, and even some handlebars flex. It's a slo-mo capture of what's happening in real life on the trail. This isn't another video where the spring force is removed from the shock and then the bike is compressed - this is the real deal.

One topic that was mentioned in this series of Field Test reviews was that the SRAM AXS derailleurs seemingly have more chain slap than their mechanical systems. While that might seem true on the trail, SRAM told Seb Stott, in theory the parts are equal. “There is no difference between the AXS and mechanical RD that would lead to a ‘lighter feeling clutch’”. SRAM went on to explain that AXS components do not have a cable and housing to stop the rotational forces of the derailleur. That’s evident on the La Sal Peak when compared to the Tracer. That doesn’t have any effect on shifting performance though.

It’s surprising how much action you get out of such an unassuming kicker, so imagine what the bike goes through on the trail. Check those bolts and make sure you hit the sweet spot on those landings!

 This is what I've been waiting for. As much as I love the downhill, I spend far more time hucking to flat. They both need to be fun.

 It was interesting to see which ones really threw him back in the air and which ones stayed stuck. That mostly comes down to tuning of the suspension, so it's interesting to see that the Intense stayed pretty stuck to the ground on the huck while they had said that it was very active while riding. The Fezzari didn't seem to bounce at all, so maybe the rebound was too slow on it. A couple of the bikes were really springy after the hit. The X2s really blew through the travel quickly, which mirrors my experience with my X2, though mine hasn't failed in nearly four years of use.

 @Explodo I think it's a mistake to assume it's only the rebond forces/settings that make a difference, we are not on a test bench with deadweight on the bikes.

Example, building on your Intense remark : maybe it is very active while riding because low damping/spring rate. Which means : can be bottomed out even with knees pretty bent, which then allows to absorb a lot more of the bike rebound.
With the Fezzari too, seems like rider technique explains a lot of the unbounciness.
(Cf on a trampoline, legs straight is what provides most rebound)

 @way2manyhobbies2keep: I've already sent my new Float X in for a warranty rebuild, so I understand that. I wonder if Fox made a manufacturing change due to the pandemic and they're working out the kinks on it. It does seem that their new stuff is all sort of breaking.
  • 7 0
 I thought it was interesting how most of the bikes seemed to sort of oscillate back and worth as they compressed. The least was the the Commencal and the most I think was the Deviate. Its like the center of gravity was sort of moving forward and aft. I wonder if this is something anybody has studied. Looks like a waste of energy and something that riders compensate for with even knowing. It must also be a function of overall build weight since the Commencal was amoung the heaviest bikes, but then the steel bike oscillated as well. Fork bushing burnishing? Interesting.
  • 4 0
 @polarflux: This is what Steve from Vorsprung was explainig somewhere on YT, you have a set of 4 springs and 2 dampers really: fork, shock, front and rear tire. That's why you can see that shock is compressing in two stages.
  • 1 0
 @senorbanana: tell that to my 2018 and 2019 X2.
Not 3 days, but their lifetimes are more like rebuilds per season not seasons before rebuild.

 Of course, if you’re running then on a yoke setup then they seem to not last as long.
  • 3 0
 @Explodo: Maybe much of the Fezzari's impact energy was dissipated by the derailleur. (Not really, but yikes, that derailleur did not fare well.)

@polarflux, @lkubica: Many factors in play, which you've mentioned, plus stiction. People get worked up about tiny, rotating bushings in shock eyelets or frame pivots, yet rarely question fork bushings. There can be a huge bending moment on those linear bushings and a lot of movement.
  • 2 0
 @polarflux: agreed. it's interesting shit going on and the variables are almost endless. is it components, settings, rider movement, hard to know.

 @polarflux: found this interesting as well. Almost as if the spring/air is pushing back at points through the leverage curve.

Anybody know what's going here?
  • 2 2
 @Explodo Yea, but this strengthens my point about the need for a pro-telemetry setup session for each rider for each bike before any of these tests. In my exchange with them, they said all they do is setup based on manufactures recommended sag, and rely on "years of experience". Talk about as anti-empiricle as your can get. So they use the "feels" method. Great. So I'll say it again, they can get a pro-level telemetry kit, dial in each rider to each bike, and come up with something akin to an accurate baseline. Or...not. :/

 It would be interesting to have a huck to flat comparing a stock bike to fully serviced and professionally serviced suspension vs like a race ready full telemetry set up factory DH and Enduro bikes to see what they do.
  • 1 0
 @lkubica: Right, I think I understand. There really are about four back and forth movement there...Tires and suspension compressing, tires rebounding and different times creating a wave or something. It's like the wedge in Newport Beach. Have to watch the video again.

 Kinda interesting that the GX derailleur on the commencal barely budged, and the GX AXS derailleur on the Fezzari looks like it's about to depart from the bike.

 Interesting to watch some bike rebound airborne and others roll away composed on the ground.

 If you are racing all of that bouncing around will cost you more then a few seconds.

 Saw that too. Must be rebound??? I'd like to hear Matt's comments on the feel of each huck to flat....
  • 8 0
 It's probably just the way he's riding the bike to make sure it bottoms. He's not absorbing any energy with his legs, so the bike will naturally bounce
  • 19 1
 Its like the "impossible climb", 90% of the difference between the bikes can be explained by inconsistency in the rider, not the bike(s)
  • 2 1
 @dennis72: Been thinking on this... If you slowed the rebound down then the bike would struggle on small to medium bumps. Looks like some bikes can handle the full range where others can only handle the small stuff.

 @Jake-Whitehouse: well, if he did them the same for each bike - it doesn't explain the difference...

 @hamncheez: every bike should get at least 3 attempts with 3 different riders.

 How much was the suspension softened for this? Were all the bikes tuned correctly with suspension and this is a real huck to flat? If so, which ones felt better or worse? We can see some bounce really bad while others stay lower on the rebound. How much of that is shock tune of external adjustments, and how much is the internal shock tune? Is it easy to feel which suspensions are linear vs. progressive? I'd love to hear this discussion.

 Wow that Fezzari derailleur action is wild!
Some derailleurs rely too much on clutch force to avoid damage and noise (not saying "chain slap" because that doesn't covers all noise sources).
Performance and price wise I love 11sp SLX, but that damn non horizontal parallelogram movement makes it so noisy... In comparison GX 12s is heaven.
Has Shimano sorted this?

 Hey @SramMedia I hope you're actively working on a Hall Lock alternative because that shit is ridiculous.

 Since pinkbike started breaking ankles and chainstays in their huck to flat videos, the average bike weight has increased to 35 pounds. . . Coincidence??

 It would be interesting to see an edit of this video using the 'face follow' effect set at the bottom bracket so we can see the suspension and rider moving around while the frame stays stationary in the shot.
  • 2 0
 I am leaning to the Intense Tracer as the smoothest travel. A few of those bikes look like they have a 2 or 3 step movement in the travel through linkages that to me detract from the quick movement of the shocks. I can see visual stalls part way through the movements. I adore these short videos I find them addicting.
  • 1 0
 A lot of that is the tire compressing and rebounding. At the end of the day, a tire is an air spring with no damper, so the damping in the shock and the fork really has to account for two different springs which would explain why they seem to stutter.
  • 1 0
 @BlackVR: the huck 2 flat used to use the same psi's and used to use one set of tyres.....i assume the preassure has continuity

 Every time I see these videos I'm like "He's good, but he's no Mike Levy." I would actually pay for more Levy content.

 @oscartheballer Ssshhhhh! Don’t say that! @notoutsideceo might come back.
  • 1 0
 It seems that the slack head tube angle of all the bikes contributed to some level of headtube flex and stiff/stuttered fork travel, but at normal riding forces, the angle of impact is more similar to the travel trajectory of the fork.
  • 1 0
 Lots of cool stuff going on that we can see when slowing it all down.. Tyre rebound is an interesting dynamic and virtually no pedal kick back on any of those landings. Shows how important a rear end behaves under braking loads and the effect then on the drivetrain. Would love to see ultra slow on the rear ends as then handle everything on heavy braking bumps. That's the real gravy in understanding the different systems there.
  • 3 0
 Contra looks like a rad bike. I hope the rebound can be dialed in better than that, though...
  • 5 1
 God damn that Contra is a thing of beauty

 Would love to see each landing at the normal speed as a comparision to the super slow motion.
Especially the landings where the bikes are "pogo-ing". Looks very dramatic in slow mo, but maybe less noticable in real time?

 Not a single one of those huge legged forks compressed in one motion. I recall pretty similar results from a bunch of 36s and Pikes. So how much are those big legs really doing to help prevent bushing bind and friction under load?
  • 2 0
 It would be interesting to see a Boxxer or 40 and see how they compare.
  • 4 0
 I think it's more a matter of the rear taking more and more pressure off the fork as it compresses. But then it bottoms and all that weight is shifted back to the fork for its last inch or so. It's drastically slowed down, I would say it's normal, no?
  • 5 0
 I also think you’re seeing the effects of having a second progressive spring (the front tire) in the system.

Conceptually, at some point the marginal force to compress the fork further exceeds that of the tire, so the tire compresses more until it bottoms out on the cushcore, then the fork goes again.
  • 3 0
 Crazy head angles will do that....
  • 1 0
 @warmerdamj: I think you're seeing which end of the suspension has progressed less into it's stroke as they ramp up. If the progression was exactly equal between the front and rear end they would travel in unison, but they're slightly different so you see a bit of a see-saw.

 I cannot get my pike to feel smooth. I could rebuild it blindfolded at this point from taking it apart and putting it back together so many times.

 @pmhobson: There is some merit to that, but why don't we see it on the rear?
  • 1 0
 @justinfoil: I think we do. Most of the rear shocks seem to compress in two steps, with the second step accounting for less 10% of the stroke by my estimation.

 A top ten list of the best Huck to flats over the years would be great to see..

 All the frames look like they held up well. The forks look a little noodle-ly, but all the forks had the similar amounts of flex and all are still great forks.
  • 2 1
 Is the little "pause" before the shocks bottom out a weight transfer thing or progressing through shims and such? Most of them seem to have the little "gooooo stop go".

 I've heard a theory that it has to do with the undamped rebound from the tires.

 Looks like they all should be using triple clamps for enduro forks as well?
  • 4 5
 triple clamps dont exsist, they are Duals.(dh forks)
  • 5 0
 @HeatedRotor: Where does the center of the dual crown fork clamp to?
  • 3 0
 @hellanorcal: The fork clamps in two places to the stanchions. ie dual clamp.
Both rockshox and Fox refer to them as dual clamps... because.... dual clamps.
  • 3 1
 @hellanorcal: Heated is correct, Dual clamps because they clamp in two places. Jordi refers to them as Dual.

not sure where this myth started but its wrong to assume they are triples - I guess the Term applies to the fact that some dual clamp(dh forks) come with 3 clamps but you can only run 2, the top one can be exchanged depending on how much Stack you want to run
  • 2 4
 @noideamtber: correct terminology is dual crown or triple clamp.
History lesson....back in the day when dual crown forks were first adapted to mtb. The idea was inspired from a moto fork. The individual crowns had a clamp bolt for each stanchion and for the steer tube, hence the term triple clamp. Moto forks still are this way today not like the cheaper manufacturing option of press fitting the steer tube into bottom can
  • 4 0
 @warrenmtb: However, On the World cup Where i was a mechanic for 10 years, We all called them dual clamp or dual crown because of them dual clamping to the tubes. - As you can imagin We spoke to jordi often - I blankly asked him one day about it and he said regardless of its Moto heritage and far as MTB/dh is concerned they are dual clamps in our Usage.

Im believe Martin from Rockshox Told us he calls them dual clamps... otherwise the fox might aswell be quad clamps...he said you only count the Stanchion clamps.

so maybe on the pinkbike side we can call them triples but from the guys that make and work on them, ill happily call them what they are.. dual clamps. thanks

 @mtbtrekracer: Explain to me how does the top crown stay tight on the steer tube then ?

 @warrenmtb: i Get what you're saying but, In the space, where they are most commonly used etc they are referred to Dual Clamps/dual crowns even by the makers, again by how many clamps on the stanchions.

 @mikekazimer: I'm 100% biased as I have a new Tracer 279. I just keep a tube and tire levers in it. So the only time I need to open it should be if I get a flat. When I did get a flat at Silver Star I flipped the bike over and it opened easily. The following day my wife got a flat and I pulled out a tube for her in seconds. Anyways a lot of engineering and thought went into making the Chad system. Perhaps your just not that good with your index finger? I have been told mine is magical... lol. I will post a video a video of me opening my Chad storage box blind folded this weekend.
  • 1 0
 @MOLDTRUTH: I prefer the upside down location of the in-frame storage on the Intense, just makes more sense to me. My SWAT is in an awkward position and weird to get to, plus it has a water bottle attached. The spec isn't great on the 279 but the frame weight is only 1# more than my SJEVO, which is a positive not a negative.
It also appears the progression is ideal on the 279 and I think there were some suspension compatibility or set up issues on this bike.
If the Reach was 485-490 I would order an Intense frameset for sure.
