Montra Rock 650B MD is a bicycle that's always delivered as a fun ride with all the big-wheel benefits of increased traction, stability over the rough and comfort. For 2015 this bicycle is equipped with the hard trail Montra frame and a 100mm fork travel with flat-welding. Designed by riders with preferences for a racy and more fun-handling bike, this frame is kept compact with short chain stays and a more challenging riding position to increase the technical-terrain handling balance.
