What LLLLL and Roots said.

Its extremely hard for most companies to do a demo day for a rear shock specifically. Way too many eye-to-eyes and baseline tunes to make it a reasonable thing. I do think companies like Push could do a "30 back money guarantee" or something.

LLLLL nailed it with how to make your air shock feel like a coil. Lol. And for a lot of riders, they'd be smart to give this a try, especially before springing (get it?) for a coil.

As far as figuring out how progressive your bike is, linkagedesign is great. That said, there are bikes that are progressive but don't work well with a coil. So YMMV.

I learned something. Never knew about the adiabatic process. Makes sense. EDIT: @David Camp call out!!! Yes! (though they missed talking about how leverages ratios could impact damping quality as well) EDITX2: I agree the coil is better for blind riding.

I know I should know better than replying to both of your comments, which remind me of a certain Billy Madison scene.

I compared a thrushaft shock to a non thrushaft shock. One blew up. One didn't. Performance difference between the two, especially considering how I like my suspension to work, was such I didn't find the juice to be worth the squeeze. Don't confuse "innovation" with "different for the sake of being different". Objectively, explain to me how removing the IFP is fixing a problem, maybe I'll change my mind. e

Stiffer compared to what? I've ridden a lot of trail bikes. All of them were setup whereby the fork could clear the downtube with ease. You are telling me shaping this tube in a way where it is curved a few millimeters to clear the fork *materially* (EG, outside of engineering computer modeling programs) affects the stiffness of the chassis? Not buying it, and my, albeit subjective, testing would suggest I'm not wrong. From the Hightower LT to the Yeti SB 55c, chassis stiffness is not an issue, and these bikes have curved downtubes. If it were more than a few mm's required to clear the crown I might change my tone, or if the frame was uber light due to this change. Neither are true. The frame IS stiff. I just think there are other ways to make a stiff frame without a compromise like this.

FWIW, I did swap the spacer stack to being slammed after taking the photos. That said, yeah, I usually do like a taller front end. So do a lot of really good pros. They must be Joeys too eh?

I'm okay with semi-proprietary shocks so long as there was an obvious need due to design. Or it is better. This is neither.

The SE4 is actually a fine tire. I didn't run it due to conditions, but there is 100% a place for it. But yeah, considering the bike's intended use, I'd like to see the SE5.

The chainguide is cool, you are right, it should have been mentioned. The crankset is heavy, a good place to save 1/2 pound but performance is fine so far.

Feel free to google my name and look at my race results. They aren't amazeballs but I can hold my own at the pro level. I also am heavy and yeah, I do ride hard. I like a progressive rear end. The Slash is somewhat progressive and adding a progressive shock works best for me. I've tried a few configurations of shock-progressiveness and the clock doesn't lie. Progressive rear end is faster for me. Is this true for everyone? No! Hell, even for me on certain tracks, I'd be smart to run a coil.

Oh, and as far as ReAktiv is concerned, I'm well aware of the technology and how regressive compression valving works. I also am buds with the dude that engineered that system on behalf of Trek. Headed to his wedding in a few days, I'll be sure to have him queue me in to any shortcoming in my understanding of how it works.

I take my reviews seriously. This was a first look, and I titled it as such. This bike is not perfect but as I noted it is one of the highest performing bikes on the market under the right pilot in the rowdiest terrain.

YMMV.

@noldog.

Where to begin. First, I'm running the keyed spacer. It helps stop the fork from impacting the frame (again, a problem that shouldn't exist to begin with) but is not enough to stop the fork entirely. Especially in the event of a crash. So its a poor solution to a problem that again, should not exist.

Second, lets find a new word for "retarded". I find it offensive. Its 2017. I'm not a pro safe spaces guy but I am a pro vocabulary guy. Choose: Idiotic. Moronic. Jerk-store-ish. (lol)

Third, last I checked the threaded BB was not full of lead compared to a press fit BB. The weight is elsewhere.

Fourth, all the 18 Fox Float EVOL forks can top out from time to time. Its not an awful top out, but can be noticed when doing a manual or similar. Its not a huge thing, and is not damper related. Comparing this to servicing a shock that blew up on ride one?

...oh wait, you just trolled me. Well. Done.

The Slash is actually a fairly progressive design. Not crazy progressive, but moreso than a lot of other bikes that you see coils on (Yeti SB 55c for instance). That said, I do believe its best with an air shock depending on what you are looking for out of the rear end of the bike.

The X2 should work, depending on size. I guess in smaller sizes, the piggyback on certain shocks can impact the downtube? Yet another silly thing Trek did that they could have worked around.

I'd ride the thru shaft shock, blow it up, get it fixed (as it should work fine thereafter) and buy something conventional, having the thru shaft as backup.

As far as hardware, yeah, that's going to depend on the shock you go with.

@Sonnenstern28

My experience is one of those that took me a second to look past the marketing and into the actual performance. Worth mentioning, I've never been a guy to run large amounts of compression damping, instead relying on tuning the spring curve to get the characteristics I want out of the support side of the fork.

Rebound I'm a bit finicky with, and consistent performance key.

Taking all of those things into account, the fork works great. I can lock it out for extended road efforts (which I do have). I also firmly believe Fox is doing something with seal and bushing design that the other guys can't get *quiet* right. Their forks remain buttery after longer periods of time.

The new EVOL spring is an improvement for sure, less the topping out which I failed to mention in this review (there is an audible thud).

Overall, excellent product, and I have a 2018 FIT4 product to compare it to. I'd upgrade if I felt it was worth it, but at this point, it just seems a wash.

Thanks B

I should have been more clear as to what Trek was claiming, as there likely are some benefits.

I am subjectively saying "the juice isn't worth the squeeze" on this one.

Too many companies have successfully dipped the downtube without making boat anchors of a bike at similar stifness levels. Even if it sheds 1/4 of a pound (which I doubt), I'd say its not worth it. Too many crashes where the frame is going one way and the crown of the fork going the other for me to say "yeah this is a good idea".

Obviously DH bikes have been dealing with this for years, so take all my ramblings with a grain of salt (double crowns!). However, those bikes are usually reinforced in this area with bumpers installed to dampen any impact.

If you look at how close the crown is to clearing the frame too, you realize its only a few mms...

For what its worth, that bike was entirely different. To the point Trek shouldn't have even kept the name the same.

The 29" Slash ditched the full floater, included an aluminum chainstay to mitigate durability concerns and has geometry that is very much in line with the "norm" when it comes to race-bred enduro bikes.

Its a handful, for sure, but that comes with the territory.

I only comment here as I don't think its fair to call Trek product junk at this point. A bit esoteric for no good reason? Sure. But as anyone who has had time on the latest iteration of the Slash can attest - its far from Junk.

To be clear, I don't think its a deal breaker or I wouldn't have purchased the bike. However, as far as helpful, I can't see one instance it does something *for* me. As far as making a whip easier I can't see one way this is the case, but I'm no Bernard Kerr when it comes to getting sideways...

I completely see where you are coming from here. I really meant, "as a racer, I'd like to see a bar mounted lockout or compression adjust". It does look ugly, complicates the bar setup and really not that useful for your everyday rider. But for a racer, it can shave seconds off a time, especially with the inclusion of "flow trails" in enduro racing. Firm the back end up and pump & pedal every bit you can. Unlock it for the rough bits.

For those just riding, flipping a switch is no big thing, and I've done plenty of climbing with the bike wide open without any issues whatsoever. Its more efficient than I'm giving it credit for, much like the new Nomad.

I'm lucky in that I've ridden a number of longer travel 29ers. And to be honest, if its north of 140mm, the design ought to be active IMO. Otherwise, what is the point? Shorter travel bikes can be more muted/efficient, longer travel bikes should be active and bump eating.

My $0.02.

Thanks for the kind words!

One thing I didn't mention - the GRIP damper is excellent. I fully planned on upgrading to the FIT4 damper, but after my time on the GRIP damper, I'm not sure I'd realize any appreciation in performance. IFP vs Bladder.

But yeah, if Trek would give up the knock block, put a 170mm reverb on this bike, spec it with codes out of the box, put a normal rear shock on it and give up the knock block they'd have a home run.

It really is an impressive bike. I applaud just how purpose specific it really is. Few thoughts pertaining to your comments.

1) I should have commented on the pressfit BB. Has absolutely no place here. There is ample room for a traditional threaded BB.

2) The design is active, this is a double edged sword but one we should be okay with in the application. The antisquat is good so as long as you are seated while pedaling there isn't an undue amount of suspension movement (similar to the new nomad in a way). With the OEM shock, the regressive compression valving David Camp designed works pretty well in keeping things further firmed up and mitigating any over-activity.

Cool enough, he's a good friend of mine and provided me with a Deluxe shock to test (no through shaft, no regressive compression valving). With this shock I did use the lever more while climbing, especially big efforts.

Overall I think a bike that is designed for EWS racing should be designed to eat bumps as well as it can, even at the expense of pedaling.

Side note - I absolutely would put a bar mounted lockout on this bike.
