Bolinas Ridge 2 2025

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 Marin's upgraded Bolinas, stepping up the fun and the components. The Bolinas Ridge 2 gets Clark’s Hydraulic disc brakes and features a SR/Suntour suspension fork, reliable and grippy off-road tires and plenty of Marin components. 

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.
