Marin 2026 Bolinas Ridge 2

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 2 ST is our upgraded Bolinas, stepping up the fun and the components. 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 ergonmically accessible as is possible.
