REAR DERAILLEUR SRAM X01 EAGLE 12V LUNAR MAIN FEATURES: - Cage-Lock Technology: With CAGE LOCK technology in the rear derailleur, removing and installing the wheel and chain becomes simpler and faster. Simply push the cage forward to create slack and lock it in place. - Roller Bearing Clutch: the ROLLER BEARING CLUTCH technology eliminates derailleur bounce and chain slap without sacrificing precision. - X-Actuation: Specifically developed for SRAM 1x, X-ACTUATION keeps shifting clean and constant across the entire cassette. - X-Horizon: The "right-angled parallelogram" design of this rear derailleur limits all movements to the horizontal axis, making ghost shifting impossible and reducing shift force. For faster, more precise shifting, the wide misalignment of the upper pulley maintains a constant distance between chains in all gears. - X-Sync: SRAM X-SYNC 1x gears offer the highest level of performance and durability. The tall square teeth of SRAM X-SYNC mesh with the chain before the traditional triangular tooth. The narrow, sharp tooth profile and rounded chamfers help manage a misaligned chain. To provide the best possible performance in muddy conditions, X-SYNC gears are designed with mud-clearing notches for the inner chain links and rollers. Designed in Germany, the X-SYNC rings are an integral part of SRAM 1x drivetrains. They do not accept imitations. - Eagle: Eagle technology represents the latest 1x drivetrain technology. Eagle is lighter, simpler, stronger, and easier to use. Eagle comes with all-new 1x components designed to deliver even greater durability and performance while maintaining a significant weight advantage over other drivetrain solutions. Eagle technology also offers an expanded gear range of 520%, equal to that of 2x11 drivetrains. - 12 speeds. - Maximum teeth: 52. - Compatible with 10-50t cassettes and with the new 10-52t cassettes.
