Who Is This For?

XCD is all about packing quality features and innovations into a group that’s compatible with Shimano 11-speed mountain bike drivetrains.  If you’re jealous of the adjustable and serviceable ratchet-and-pawl clutch, sensible wide range gear ratios, and ergonomic shifting action found on our ADVENT and ADVENT X groups, XCD is a great way to get started mixing and matching, all at the highest quality level.
