Shimano Rd M820 Saint Shadow Rear Mech

Super wide links create a rigid structure that resists twisting and improves durability. The integrated skid plate protects the derailleur in the event of an impact. It also features a switch which enables heavier spring tension to reduce chain bounce. With the mode converter you can set a "wide" mode with 11-32 teeth for freeride use and a "close" mode with 11-28 teeth for downhill use.
