Description
Born for wild rides on gnarly backcountry trails, the Full Stache 8 Mountain Bike from Trek actively goes in search of rugged terrain. The 130mm of front and rear travel, with top drawer RE:aktiv technology and the unique Trek Active Braking Pivot allows the suspension to perform smoothly even under hard braking. With the Mino Link you can adjust the geometry from slack to slacker, delivering greater stability when descending at high speed and the wide Boost dropouts deliver the stiffness of 27.5" wheels to a 29" build so that power transfer and responsiveness are enhanced. A dropper post gives you even more control and freedom of movement and shorter chainstays give you the sort of traction that will propel you up punchy inclines to hold pace on the trail.
SRAM provide GX Eagle components for reliable gear shifting to the 1X 12-speed drivetrain and the Guide R hydraulic discs brakes with 200mm front and 180mm rear rotors have stacks of stopping power, fit for any conditions you may encounter.
