Sram XX1 Type 2.1 Rear Derailleur

The Sram XX1 Type 2.1 Rear Derailleur provides precise and quick changes, eliminates displacement, facilitates wheel removal, and provides transmission stability, which characteristics are necessary for mountain biking. It is compatible with 42 tooth and 11 speeds and includes a bearing clutch that eliminates chain bounce and bumps.

This bike rear derailleur is made with carbon, while the pulley bearings are made of ceramic. The X SYNC technology provides good performance, easy shifting, and silent operation. The X HORIZON technology allows for faster and effortless shifting.

Besides, it comes with a cage lock that makes wheel removal and installation easier. It features X-Actuation technology specially designed for 1x transmissions and avoids ghost shifting.
With its ®horizontal parallelogram® design and pulley offset, X-HORIZON® keeps the chain gap constant across all 11 gears, providing fast, precise shifts.

By limiting all movement to the horizontal axis, this design is faster, reduces shift force and eliminates ghost shifting.

ROLLER BEARING CLUTCH® technology reduces bounce and chain slap.

CAGE LOCK® technology makes wheel removal and installation easier than ever before.

Paired with the XX1 shifter, the X-HORIZON® RD forms the backbone of X-ACTUATION® technology for unbelievably smooth shifting action.Features:- This XX1 rear derailleur is an integral part of the SRAM 1x® drivetrain system.

With ROLLER BEARING CLUTCH® technology, derailleur bounce and chain slap are eliminated without sacrificing precision.X-ACTUATION®:Developed specifically for SRAM 1X, X-ACTUATION keeps shifting sharp and consistent across the entire 10- to 42-tooth cassette.X-HORIZON®:The X-HORIZON® rear derailleur®s ®straight parallelogram® design limits all movement to the horizontal axis, which makes ghost shifting impossible while also reducing shift force.

For quicker, more exact shifting, the large upper pulley offset design maintains a constant chain gap across all gears.X-SYNC®:SRAM X-SYNC® 1X chain rings provide the highest level of performance and durability.

The SRAM X-SYNC® tall square teeth edges engage the chain earlier than traditional triangle shaped teeth.

The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain.

To provide the best possible performance in muddy conditions, the X-SYNC® chain rings have been designed with mud-clearing recesses for the inner chain links and rollers.

Engineered in Germany, X-SYNC® rings are an integral part of the SRAM 1X® drivetrain.

For 2x10V systems.

- Compatible with cassettes 11-42T.
