With alloy nipples, a nice, wide, lightweight rim and quality sealed bearing hubs, the Bontrager tubeless-ready 29er wheels are easily the lightest on test, making the Stache incredibly fast from the gun and easy to get lent over in corners. One of the key advantages of 650b wheels is that with like-for-like components they will be lighter than their 29in counterparts.
2015 TREK STACHE 7 BRAKE SPECS FULL
The entry-level Evolution series also has a distinct lack of mid-stroke support, and while this makes it very easy to achieve full travel on every ride, it does nothing for your ride confidence when the fork plummets through all of its travel when landing a drop or having to negotiate a tight, steep switchback. Yes, the oversized 15mm quick-release and 32mm upper tubes ensure that it’s plenty stiff enough for good steering precision, even with 29in wheels, but there is a harshness to the action of the Fox fork that translates to a slight numbing of the hands. There was a time when the 120mm-travel 32 Float would have been a sign of excellence, but since the introduction of the CTD damper in 2012, Fox forks no longer carry the same cachet. It’s not just the frame design that’s unique on the Trek it’s the only bike on test to sport a Fox fork.
2015 TREK STACHE 7 BRAKE SPECS UPGRADE
So your first upgrade will definitely be a dropper post, and Trek provides Stealth routing to make it possible if that’s the way you want to go. There is one downside to the flattened seat tube design, though: you can’t drop the saddle more than an inch or two. Was it worth all the hassle? Well, it certainly looks amazing and the 442mm chainstays, while not being super-short, are shorter than on most 29ers. The final piece of the puzzle was to flatten the back of the seat tube to make everything fit together. This, in turn, has allowed the rear wheel to be tucked in nice and tight to the BB without scrimping on tyre clearance. Keeping the chainstay length in check was a priority for Trek when developing the Stache and, by switching to the stiffer bolt-through dropout design, the engineers have been able to retain the desired frame stiffness for tracking and power delivery while ditching the seat and chainstay bridges.
The frame shares most design features you find on Trek’s full-suspension trail bikes, including a tapered head tube, ISCG tabs on the BB for fitting a chain device and 142x12mm rear dropouts the last of those isn’t commonly found on a hardtail - all of the other bikes on test this month have regular QR rear dropouts. First introduced last season, the Stache is billed as a trail-ready 29er hardtail designed to meet all the exacting demands of the modern mountain biker.
