Tecnologies

Shimano Shadow RD+
Less distraction quiet drive train now is real! Rear derailleur stabilizer Shadow RD+ reduces chain slap and save you from chain drop. Lighter and more efficient than roller type chain device!

Bump Stopper
The rear derailleur bump stopper improves rider focus by silencing derailleur noise in rough conditions. This high-durometer urethane bumper prevents chain slap by absorbing impacts between the B-link and the rear derailleur B-tension adjustment screw.
