Marin Bikes Bolinas Ridge 2 ST GREY

Setting a new benchmark in value, the Bolinas Ridge ST 2 is one of the best priced bikes to offer both a 1x (single front chainring) gearing and hydraulic disc brakes.

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. This can make for smaller/younger riders getting into an adult bike which generally have more ability to last longer as youth go through growth spurts.
