Efficiency was the key principle when designing the XTR M980 10-speed rear derailleur. The derailleur was designed with Shimano's Shadow technology, using a longer swing arm and a tighter spring for crisper shifting when you want it, and less 'ghost shifting' when you don't. This Dyna-Sys rear derailleur will stay in adjustment longer and deliver consistent performance with each ride.
