Key Points

Huge 3inch 29er Plus tyres offer improved rollover and incredible traction
Backbone of the Stache frame is a wide press-fit BB92 shell the promotes direct power delivery
Bontrager’s 80mm Rhythm Pro stem had to go to sharpen the Stache’s steering and shift rider weight rearwards

Trek has never been afraid to experiment with alternative wheel sizes. The Stache 9 29+, however, takes this open-minded approach to a whole new level, with 3in tyres, mounted on 50mm wide 29er rims and slotted into ultra-short chainstays.

The monster-truck tweaks also include wider Boost 110 and 148 dropout spacing, to accommodate those bulbous treads. Beautifully-made frame, with extensively sculpted aluminium tubing.
