RECREATIONAL MOUNTAIN BIKING

ENTRY-LEVEL RIDERS

FITNESS DIRT ROAD RIDING

The perfect blend of performance, value and fun, the Marin Bolinas Ridge is ideal for riders that are new to mountain biking or simply want a low-hassle, low-cost bike to explore off-road.

The Bolinas Ridge 2 is our upgraded Bolinas, stepping up the fun and the components. The Bolinas Ridge 2 gets an upgrade to Clark’s Hydraulic disc brakes and features a SR/Suntour suspension fork, reliable and grippy off-road tires and plenty of kick-ass Marin components. The Bolinas is ideal to break out onto the trails and push your own boundaries.

Depending on size, the Bolinas Ridge comes with either smaller 27.5” (sizes XS to M) wheels or larger (sizes M to XL) wheels to guarantee a perfect fit.

Key upgrades over the Bolinas Ridge 1:

  • Shimano Altus 3x8 drivetrain
  • Clark's hydraulic disc brakes
  • SR/Suntour XCM DS fork
