Marin Bolinas RIDGE 1 ST 27.5 Mountain Bike

With a lightweight aluminum frame, a trail-capable suspension fork, MTB tires and all-condition disc brakes, the Bolinas Ridge has everything you need to break out onto the trails and push your own boundaries.

The Bolinas Ridge ST 1 is the best value model in the ST family, offering bags of bang for very few bucks. Components include powerful Tektro mechanical disc brakes, an SR/Suntour suspension fork and reliable and grippy off-road tires.

This new step-thru frame is only available with 27.5 wheels across the XS - M frame size to keep it as ergonmically accessible as is possible.
