The Shimano RD-M786 XT SGS Rear derailleur is perfect for all-mountain and marathon mountain biking. It has been specifically designed for fast and precise gear shifting and thus supports a more performance-oriented riding style. The quiet rear derailleur is equipped with a stabiliser to reduce chain slap and prevent it from jumping. Plus, it reduces the chain sagging. All this thanks to the Shadow Plus technology. The Dyna-Sys mechanism serves to provide a significantly softer gear change without disturbing your cadence. Off-road riders are sure to lose themselves in a flow state with the RD-M786 XT SGS Rear derailleur!
