The Marin Bolinas Ridge ST 2 has everything you need to hit the trails and push your limits. With a lightweight aluminum frame, trail-capable suspension fork, grippy MTB tires, and all-condition disc brakes, it delivers outstanding value for the price.

Similar to the Bolinas Ridge 2, the ST 2 step-thru version steps things up even further with upgraded components. It features Tektro hydraulic disc brakes for superior power and control, an SR Suntour XCM DS suspension fork, and a wide-range Shimano Essa 1x8 drivetrain for simple, efficient gearing.

This new step-thru frame design is available exclusively with 27.5" wheels in sizes XS–M to maximize accessibility and ergonomic comfort.
