MarinThe Bolinas Ridge bikes have everything you need to break out onto the trails and push your own boundaries. With a lightweight aluminum frame, a trail-capable suspension fork, MTB tires and all-condition disc brakes, offering the best bang for your bucks.
Similar to the Bolinas Ridge 2, the Bolinas Ridge 2 ST mountain bike is our upgraded Bolinas, stepping up the fun and the components even further. The Bolinas Ridge ST 2 gets an upgrade to Tektro Hydraulic disc brakes and features a SR/Suntour suspension fork and a wide range Shimano 1 x 8 Essa drivetrain and gearing.
This new step-thru frame is only available with 27.5 wheels across the XS - M frame size to keep it as ergonomically accessible as is possible.
