RECREATIONAL MOUNTAIN BIKING

ENTRY-LEVEL RIDERS

FITNESS DIRT ROAD RIDING

The perfect blend of performance, value and fun, the 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 1 is the best value model in the Bolinas family, offering bags of bang for very few bucks. Components include powerful Clark’s mechanical disc brakes, an SR/Suntour suspension fork and reliable and grippy off-road tires all of which are ideal to break out on 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.
