Dropper post internal routing
Not ready for an internally routed dropper post now, but want to keep your options open? Select frames are equipped with the proper entry and exit points to accommodate internal routing for a Stealth seat post.
Horizontal Sliding Dropout
Horizontal sliding dropout with redundant securing mechanisms allows for no-slip singlespeed or geared options and provides the ability to dial in the geometry to match each rider’s style.
How do you fit a 29" tire without elongating the wheelbase? Elevate the driveside chainstay up and out of the way.
Built for 1X
Stache is optimized for a single chainring. No front derailleur means a tighter wheelbase for a lively ride.
Wider dropouts (110mm front, 148mm rear) give you the stiffness of a 27.5" wheel with all the benefits of a 29" wheel, and Boost148 in the rear lets you run wider tires and a larger chainring without affecting q-factor and pedaling efficiency.

Sizing & fit
The charts below show our recommended sizes based on height, but there are some other factors, like arm and leg length, that determine a great fit. That’s why you’ll see some overlap in our recommendations. Not every rider who’s 5´8˝, for example, will fit on the same size bike. The best way to find your perfect fit is to consult the experts at your local Trek retailer.
