Doubly stiff: Boost148/110
Wider 148mm rear and 110mm front hub spacing on 29ers creates stronger, less flexy wheels and allows for wider tires, shorter chainstays, and more chainring options.
Smooth, controlled braking
Our patented ABP (Active Braking Pivot) keeps your suspension from stiffening up when you're on the brakes, giving you confident, steady control.
Trek suspension package
Advanced tech, like ABP (Active Braking Pivot), Full Floater, and RE:aktiv, makes Trek the best-riding full suspension bike.
Short, lively chainstays
Thanks to Boost148, we can shorten the chainstays on 29ers from 452mm to 437mm for a more spirited, lively ride.
