The redesigned XX1 Eagle rear derailleur takes a new place in the world of shifting performance, offering uncompromising cyclists and those who enjoy setting up dream bikes a top-of-the-line option. The crisp, precise feel of the XX1, so loved by athletes, now has a redesigned cage for easier shifting management.
The chain is even better. The XX1 Eagle derailleur works seamlessly with the new 10-52T cassettes and is backwards compatible, so it will also work with 10-50T.
