Sram X01 Type 2.1 X-Horizon Rear Derailleur 11 Speed BlackThe Sram X01 Type 2.1 X-Horizon Rear Derailleur uses geometry to keep the chain gap the same across all 11 gears, for smoother shifting. By simplifying the process of taking vertical height out of operation shifting requires less force and prevents ghost shifting. The Roller Bearing Clutch Technology reduces chain bounce and slap. The Cage Lock Technology makes wheel installation and removal a very easy process. Exclusively for Sram 1x11 setups. Sync 12-tooth pulley design reduces noise and maximizes chain control by alternating wide/narrow teeth to mirror chain profile, while upper pulley offset maintains chain gap to cassette. Forged aluminum links, B-knuckle, and inner cage with a carbon fiber outer cage. Aluminum and stainless hardware with sealed cartridge bearing pulleys. Available in Black.710845764035
