SRAM X01 X-Horizon 11spd Rear Derailleur (Long Cage)

Thanks to its "horizontal parallelogram" design, X-HORIZON™ can keep the chain gap the same across all 11 gears. By taking vertical movement out of the equation, this design doesn't just make shifting faster-it reduces shift force and eliminates ghost shifting.

Key Highlights Are
X-HORIZON™ design reduces shift force, ghost shifting and chain slap
12-tooth X-SYNC™ pulley wheels
Large upper pulley offset automatically adjusts chain gap
Sealed cartridge bearings
Carbon cage
