Mountain bike rear derailleur X01 Type 2.1 11 Speed

With its ®horizontal parallelogram® design, X-HORIZON® can maintain the same chain gap in all 11 gears.

By eliminating vertical movement from the equation, this design not only makes shifting faster®it reduces shifting force and eliminates ghost shifting.

BROLLER BEARING CLUTCH® technology reduces chain bounce and chatter.

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

When combined with the X01 shifter, the X-HORIZON® RD forms the backbone of X-ACTUATION® technology: the key to a completely smooth shifting action. Features:- Large top pulley offset automatically adjusts chain gap- X-HORIZON® design reduces shifting force and ghosting- 12-tooth X-SYNC® pulley wheels- Sealed cartridge bearingsSpecifications:- Speeds:11 speeds- Material:Carbon fiber or aluminum outer cage- Weight:250g- Compatibility:1x11 X-ACTUATION®- Bearings:Sealed cartridge bearings- Cage size: Long- Pivot design:Horizontal parallelogram design- Maximum tooth:42t- Pulleys:12 tooth X-SYNC® pulley wheels- Technology highlight(s):X-ACTUATION®, X-HORIZON®, X-SYNC®, ROLLER BEARING CLUTCH®, CAGE LOCK®Technology:CAGE LOCK®:With CAGE LOCK® technology in the rear derailleur, removing and installing the wheel®as well as installing the chain®becomes faster and easier.

Simply push the cage forward to create slack and lock it in place. ROLLER BEARING CLUTCH®:Rear derailleurs offer maximum drivetrain stability®, even on the most challenging terrain.

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

For faster, more precise shifting, the large top pulley offset design maintains a consistent chain gap in all gears. SRAM X-SYNC®:X-SYNC® 1X chain rings offer the highest level of performance and durability.

X-SYNC® high square tooth edges SRAM engage the chain sooner than traditional triangle shaped teeth.

The sharp, narrow tooth profile and rounded chamfer edges help manage a deviated chain.

To provide the best possible performance in muddy conditions, X-SYNC® chain rings have been designed with mud clearance 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 11-42T cassettes.
