The Shimano XTR M980 Rapidfire Plus Shifters offer 2-way release for different riding or shifting styles (index finger or thumb.) Pull it with your finger or push it with your thumb, each click of the upper lever releases cable, the same as it always has, but now it swings both ways. The fastening clamp offers variable positioning, allowing you to set up your cockpit just the way you'd like it. Shimano SIS-SP41 outer housing and coated stainless steel cable provide super smooth shifting. Includes front and rear shifters.
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.
The Shimano XTR FD-M985 top swing front derailleur is designed for use with the Shimano FC-M985 or FC-M980 2x10 cranksets and features universal clamp band mounting. The derailleur accommodates top or bottom pull cable routing.
The 10-speed Shimano XTR M980 cassette delivers consistently smooth shifting performance and durability in an innovative, lightweight package. A redesigned tooth profile has been optimized for the narrow HG-X 10-speed chain and Shadow rear derailleur. This lightweight cassette features 5 titanium cogs.
The XTR CN-M981 HG-X chain has been specifically designed to meet the needs of the 10-speed Dyna Sys mountain drive train. This new chain uses Sil-Tec, an advanced surface plating technology to increase both performance and durability.
