Shimano's Deore XT Rear Derailleur uses cold-forged construction and cutting edge technology to deliver crisp shifting, real-world reliability, and trademark precision. The Direct Mount uses less parts and provides a solid connection to your machine. The Shadow design tucks the rear derailleur closer to the wheel, which keeps it out of the way of roots and rocks as you're flying down the trail. A strong spring prevents chain slap, reducing noise while on the trail, and improving 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.
