Marin Rift Zone 29 Carbon XR 2023 Bike

The Rift Zone is our 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.

Technology

Uniconditional Carbon Fiber Frame

The Rift Zone Carbon 1 and 2 models feature high modulus carbon fiber and monocoque construction to deliver the lightest, most capable, Rift Zone that Marin has ever made.

Series 3 Aluminum Frame

Rift Zone 1, 2, and 3 models feature Series 3 aluminum frames, with detailed forgings, highly manipulated tubes, and full internal cable routing, giving the rider a high feature and high-performing upgrade-worthy platform.

MultiTrac Suspension Technology

MultiTrac is an acclaimed suspension system, fine-tuned to have a balanced ride capable of absorbing big hits with an efficient pedaling platform. The rocker link provides a progressive leverage ratio for the rear shock for small bump sensitivity and the feeling of a long travel system on large drops and rocks.

Internal Routing

Both carbon and alloy frames sport full internal cable routing in the front triangle with Marin’s all-new internal cable routing grommets, providing a clean and rattle free cable set up.
