The 7-speed rear derailleur makes shifting smooth and reliable no matter where you ride. By maintaining consistent chain gap across all seven gears, this derailleur eliminates vertical movement for faster shifting, reduced shift force, and an end to ghost shifting. Roller bearing clutch technology and the 12-tooth X-Sync pulley wheels hold the chain in place and reduce chain slap. Cage lock technology makes wheel removal and installation easier than ever. Pair this derailleur with the X01 7-speed shifter and you have completely smooth shifting action.
*For frames that have less than 25mm of chain growth use the short cage version, for frames that have more than 25mm of chain growth use the medium cage.
