The Marin Rift Zone is Marin 's most speed oriented MultiTrac bike, created for the rider looking for the speed and roll over capabilities of 29” wheels in a trail capable package. Long, low, and slack trail geometry is more aggressive than an XC race bike for more control at top speed, and more fun while chasing seconds.
The Marin Rift Zone XR is the newest and rowdiest member of the Rift Zone Carbon lineup, designed around a 140mm travel fork, paired with the included Fox Factory Coil rear shock.
