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.

This derailleur not only answers the Eagle drivetrain’s need for greater capacity, but is also the next evolution of SRAM's proven, 1x-specific X-HORIZON design. The larger, 14-tooth X-SYNC lower pulley, allows 10- to 50-tooth cassette capacity in this compact design, and also adds to Eagle’s overall smooth-pedaling feel. SRAM's Type-3 ROLLER BEARING CLUTCH features a smoother torque curve for a quieter, more consistent operation and feel. CAGE LOCK has been moved back and out of the way, protecting it from trail debris. A redesigned, robust mounting system further improves the Eagle derailleur’s performance and overall durability.

Run silent, run deep. Shimano's ZEE rear derailleur uses a short cage and a Shadow profile to keep tucked out of the way of rocks, roots, whatever. The Plus part is a one-way clutch system that stabilizes the cage and your chain when ripping over rough terrain. Chain slap and the noise that goes with it, as well as dropped chains, are virtually eliminated. Of course, it still has the smooth action and sniper-like shifting that Shimano is rightly famous for. Freeriders and trail riders can run a typical MTB cassette like an 11-32, 11-34, or 11-36. And DHers can choose the close-ratio version and run a road cassette like 11-23, 11-25 or 11-28.

Eleven speeds to rule all the trails. That is the X1 Rear Derailleur's motto. It packs a massive amount of technology into its compact, lightweight aluminum body. This 11-speed gear changer uses a “horizontal parallelogram” design that limits all movement to the horizontal axis, reducing the force it takes to shift. The Type 2 clutch is brilliant. This self-lubricating, one-way roller clutch controls your chain tension to eliminate chain slap and give you smooth, consistent shifts over any terrain. For quicker, smoother, more exact shifting, the large upper pulley's offset design maintains a consistent chain gap across all gears.

Chorus 11-speed's shifting precision is comparable to its older siblings Record and Super Record. The design and geometry of the rear derailleur are exactly the same. The only difference lies in the materials used, which made it possible to keep a favorable price without lowering the performance levels.

If the Potenza 11 rear derailleur looks almost identical to that of the Super Record, it is because its design takes a great deal of inspiration from the recently launched Revolution 11+ drivetrains and guarantees a similar degree of shifting performance as a result. Changing only the materials used in its construction the Potenza 11 rear derailleur is capable of shifting with the precision and speed of the Super Record version with the only compromise coming in the form of weight. Thanks to sophisticated solutions such as Embrace technology, riders using Potenza 11 can count on highly efficient power transfer, secure grip, efficient chain/cassette interface and longer component life previously attributed only to the elite mechanical transmissions from Campagnolo. - Lightweight technopolymer upper and lower bodies reduce weight - Features the same shape of Super Record, offering similar shifting performance - Special lightweight rubber pulleys reduce friction and noise - Compatible with Potenza and model year 2015 and newer Chorus, Record and Super Record - Pulley rollers on bushings in sintered material - Drivetrain Speeds: 11 - Cage Length: Short - Chain Wrap Capacity (teeth): 37 teeth - Largest Cog: 29 - Weight: 211 grams
