Spotted: Unreleased Trek High-Pivot Enduro Bike

What have we here?

It's peak riding season, and that means next year's hottest bikes are getting some time in the sun, working out the kinks before they hit the market. A Pinkbike reader happened to be out and about at the same time as a few Trek employees, and spotted what looks to be a new enduro bike that's nearly ready to go. It's safe to assume that this is the next Slash, and it appears to be a high pivot.

My guess is that the engineering team at Trek are taking notes from their new mid-high pivot Session, and applying the same principles to the enduro bike platform. The photographed bike looks quite similar to a few other idler-equipped enduro bikes on the market currently, namely the Devinci Spartan, the Norco Shore, and the Hope HB916.

The idler wheel looks to be a bit bigger than some of the other bikes mentioned; larger idler wheels are typically used to reduce the drag in a system, and should reduce wear with the increased chain wrap. There's also a pulley wheel that extends from the bash guard, another measure that's likely to improve chain wrap and reduce noise or the chance of derailment.

There appears to be an accessory mount underneath the top tube, and it's safe to assume Trek will continue using their in-frame storage system that they've featured on a few of their past models. One interesting detail that I'm seeing in this photo is what looks to be a bolt-on lower shock mount, perhaps with the ability to swap out for other sizes and kinematic tunes. This is some pretty deep speculation, but hey, that's what Spotted shots are all about.

The tread pattern of this tire looks similar to Bontrager's existing lineup, but the lack of a hot patch suggests they're experimenting with different casings or compounds.



We've reached out to Trek for comment, and their reply was a simple and mysterious one liner:

“It’s only real if you believe.”



And thanks to @theflowkid for the keen eye, great work out there!

 Sure is, I work at the shop there and the Trek guys were riding our shuttle when I grabbed that photo.

 why don't all full suspension bikes come with that rear fender?

 The high pivot thing has me laughing. I’ve been in the industry and riding since the mid 90s and seen it all come and go including high pivot. Don’t get me wrong, I love the idea and have owned a couple, but the bandwagon thing is just so hard to watch. The last high pivot bike I had was a Commencal Supreme SX…that bike sold so poorly it was discontinued in just two years and here we are just a couple years later and it’s all anyone wants. I’m just here for the show now.

 I'd say if you have a good feel for bike geo then you can feel the effect of a rearward axle path as you're compressing through corners / gnar. Trends or not, there's data on how it can work well with how hard the bikes are being ridden? I always see mtb go through a trend of small brands doing something experimental, finding success, and having the big brands dip into the selected market. To me it's just how this market will naturally evolve

 short headtube, low stack, disappointing
  • 1 0
 I wonder if it’s just a VERY tall rider. I’m not one to typically comment on peoples’ set-ups (largely because I don’t care), but that is a LOT of forward bar-roll and it makes me wonder if TREK didn’t have a larger frame for them to test so they are attempting to get as much rise in the front end as possible.
  • 3 0
 @cwatt: i wouldnt be surprised if it went the same way as the Fuel did, so close to a perfect bike but forgot about stack height, to be fair ive seen alot of the fuels in the wild but all with maxed spacers and high rise bars, i demo'd one with similar setup and the front end flex is awful.
  • 1 0
 @HeatedRotor: Oh gosh, I think you’re onto something here. I wasn’t sure which Fuel you were referring to so I had a look at the new Fuel EX. For a size medium the head-tube length is 100mm. I ride a Transition Scout (also 150mm/140mm) and my size medium is 125mm. My very basic math tells me that’s 25% more (lol) which I’m prepared to call significant. I wonder what TREK’s rationale is behind this design decision. TREK, you out there???
  • 2 0
 @cwatt:

It’s a 29’r; therefore more bb drop and a longer axle-crown. This would give it similar or even more stack height than a 27.5 bike like your scout with the longer head tube.
  • 1 0
 @cwatt: They'll give you some answer that they did a bunch of research and it came out as an ideal Geo. Not sure if they got anyone on it that will actually ride the bike.

Stack has to grow with reach or everyone looks like a giraffe on them, spread out and bent down(becoming common with modern bikes anyway because reach is long on alot of bikes)

Im not a huge German engineering fan but Brands like YT and Canyon have got their sizing pretty darn good, with YT running slightly shorter.
  • 1 0
 @BRRider: Frame stack is still the same, its measured as a frame with stock configuration. i can put 27.5 wheels on my bike... guess what, stack doesnt change lol
  • 2 0
 @HeatedRotor:

You are correct. Other than the bb height the geo will not change. 29ers have more bb drop built into the frame so that you have an appropriate bb height with 29 inch wheels fitted. The bb is well below the wheel axles on a 29r, this is what gives them the touted ‘in the bike feeling’. If you slapped 27.5 inch wheels in your 29’r you’d drop almost an inch in bb height. Combine that with a longer axle to crown fork to accommodate the 29 inch wheel and you have a similar or larger stack height than a 27.5 bike. Compare the size for size geo charts of that medium scout to to the medium fuel and see which one has more stack height despite the 25mm longer headtube of the scout.

29ers are generally always going to have a quite a bit shorter headtubes than a 27.5 bike. Have a look at some geo charts. Mullet bikes may yet have an even shorter headtube. I’m not arguing for short headtubes. I’d prefer a well braced steerer tube.

What you are seeing with Trek and the dumb giant stack of spacers is because that is what they ship with. You can adjust fit and change bar rise to suit your needs if you have some extra steerer showing. Alot of people don’t care(run what ya brung) or don’t know how adjustable the cockpit of a bike is.
  • 1 0
 @BRRider:have you ridden the New fuel? its one of those bikes that seriously needs a bigger headtube for the sake of stiffness. the whole fit and height is another problem all together but you tend to get both at once
the fuel exe is in the same boat, i was actually lucky enough to swap my full power ebike for a EXE for a lap of the bike park last weekend and it had so much back and forth flex it felt like it was going to break - when you turned the Handle bars with the front loaded it was like your internet with lag lol.

 @HeatedRotor:

I have and know a few people who own them. That’s the first time I’ve heard that anecdote. It wasn’t something I’d read in any of the reviews I checked out either. I wasn’t commenting on the flex issue you’re having. Was just trying to help explain the fit/stack height thing. As an example, Santa Cruz who have always had nice long headtubes, chopped 25 mm off the large 5010 when it went from full 27.5 to a mullet bike with the newest generation. It’s kinda the nature of the beast. I’m not saying it wouldn’t be nice if Trek added an extra 5-15 here or there to the headtubes but on a 29’r or mullet you can only go so far.
  • 1 0
 @cwatt: scout is 27.5 though, so the front end is actually still lower than a 29er with a 100mm head tube (by about 15mm).
  • 1 0
 @BRRider: should have kept scrolling to this comment, yep agree. You beat me to it.

And like you say sure if you switched to 275 the stack would be the same, but with 29er BB drop the bike would be unrideable so it's pretty irrelevant. To function it would need less BB drop which would reduce stack. 29 will always have more stack for a given fork travel and head tube length.
  • 1 0
 @KennyWatson: @BRRider @HeatedRotor It’s obvious I’m not contributing much to this conversation, but I am learning which is great.

So, what little I can offer is the Transition Sentinel (160mm/150mm) has a 110mm headtube for a ‘medium’ which is 10mm or 10% longer than the Trek Fuel EX. From what I’ve gathered from your comments, it seems this 10mm or 10% might just be the difference people are looking for.
  • 1 0
 Long headtubes look shit so the big companies won't do it. Good looking bikes sell. Ugly high-tech bikes (e.g. Nicholai) barely sell by comparison even if there's evidence they might perform better.

If you really believe in high stack buy from a niche company that is making the geometry you believe in
  • 1 0
 @tom666: Those same companys(trek) make bikes with longer headtubes/stack lmao
  • 1 0
 @cwatt:

Yes, but depending on bb drop. Medium fuel has 5mm less stack than medium sentinel. So with a 105mm headtube the trek would fit nearly identical to the sentinel, if you consider the sentinel to have ‘ideal geo’. Even without that 5mm it would still fit ‘taller’ (it has more stack) than your scout though. It’s just splitting hairs at this point when it comes to fit. Structurally I like the idea of a longer well braced headtube. I’m sure the little stubby ones are designed to take the licks though.

If people really just want to poopoo trek they could probably find better reasons than the way they fit. It seems a bit personal for Mr HeatedRotor for whatever reason.
  • 1 0
 @BRRider: im not wanting to shit on trek because of 1 bike.. but for me the fuel was going to be my next do-it-all bike, Coil, mullet, adjustable, good geo untill you see the low stack number, i gave it the benefit of the doubt and went an demo'd one. cool - it rode well but i had to put all the stem spacers under the stem and asked if they had higher bars... they were nice enough to setup like that and i rode it, holy flex in the front....

We can keep using bigger forks on trail bikes if we wont beef up the headtube/steerer aswell.

Sentinel has its own issues, its also priced stupid high here.

 @HeatedRotor:

I get what you’re saying but the stack seems pretty average compared to what’s out there. You mentioned yt as a brand doing good things with fit. The yt Jeffsy has only 5mm more stack throughout the sizes and only 2mm more once you get to an xl. They have similar reach numbers as well. When setup as a mullet the fuel actually has the same or higher stack than the jeffsy 29. It’s pretty well the same story with the canyon spectral as well.

I slap 40 or 50mm bars on all my bikes and remove as many spacers as I can. Works for me. Santa Cruz still has some higher than average stack heights if you haven’t looked at them. They have 3 different mullet bikes that all rip if you’re willing to pony over some cash for meh value.

 @HeatedRotor: I have owned the last two generations of the EX, the Slash, and now I have the new EX with over 500 miles on it since May. Admittedly, I run my new EX with 5mm of additional spacer under the stem (upgraded the fork so I cut my own steerer tube) and my I9 stem in the high position, but I did this purely for resale value of the fork, and because I can always lower by bars by way of spacers. I've never needed, nor wanted, more stack on any of my Trek's.

That said, with my new EX and the "extra strack" from a longer steerer tube and taller stem, I never experience unwanted flex in the headtube. I ride my Ex hard, and IMO it's a very quiet and tight feeling bike. In fact, I've been able to open up and find speed that I haven't been able to on all my other bikes, so this is also my "enduro" rig for local SE races.

I also know quite a few people who ride the new EX, and not one person has felt any flex in the headtube area. It sucks that you're feeling that flex, but it's also interesting that you're the only one that's mentioned it.

 Seat angle looks good / fixed which is a great thing for the Slash, wasn‘t great for long legged people until now. Otherwise the divere Slashes ride great and are interesting bikes.

 Whos buying these super long travel high pivot bikes? Unless you make it your park bike or you are pedaling straight up and bombing the most gnar of gnar everyday seems like a lot of compromise. The old Slash was a good pedaling enduro bike that could easily be used a trail bike when you're not riding the heavy stuff.

Also that is such a copy of specializeds paint jobs its hilarious.

 Maybe it’s intentional misdirection on their prototype.

 I hope this is an addition to Trek's line up - would be great if this was 170/180 travel super Enduro and they carried on making the current Slash and lowered the prices.

The current slash is a great bike because of it's all-roundedness. The bike pedals great.

Maybe Slash will go high-pivot and they'll re-do the Remedy at 160mm as more of an all-mountain / enduro all rounder.

 Maybe something to do with reducing pedal kickback with the shorter travel? Just guessing, no suspension design expert by any means. Or just giving that ‘dh travel feel’ from having a more rearward path?
