Shimano's Deore XT Rear Derailleur uses cold-forged construction and cutting edge technology to deliver crisp shifting, real-world reliability, and trademark precision. Plus-type derailleurs use a lever-actuated clutch spring to prevent chain slap, reduce noise while on the trail, and improve chain engagement when riding over rough terrain. Sealed pulley bearings keep things spinning smoothly, and wide plate construction prevents the derailleur from getting clogged with mud and debris.

Three decades ago, SRAM was founded on a product called Grip Shift and an idea that shifting a bike should be easier, better and more intuitive. It’s more advanced than the original, but the XX1 Eagle Grip Shift follows in the same tradition of making shifting easier, better and more intuitive. The XX1 Eagle Grip Shift system includes robust internals that make it more durable and its shifting performance more precise. But just like the original, it is total control in the palm of your hand.

In short, it's everything you want in a high-end drivetrain. - Two alloy large cogs and a full alloy spider eliminate unwanted weight - Ramped cogs aid in shifting under load - Continuously molded construction maintains straightness and durability - Compatible with standard HG freehub bodies and 10-speed chains - Cassette Body Type: Shimano/SRAM 8, 9, 10 Speed - Cassette Cogs: 11-13-15-18-21-24-28-34-40-48
