The X01 11-Speed Rear Derailleur
- Type 2.1 from SRAM knows that every mountain pushes you further, so it delivers quicker shifting, smarter gear steps & more precise chain management. The Type 2.1 now features an internal change to the clutch mechanism which improves performance & longevity compared to the previous Type 2. 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, but also reduces shift force & eliminates ghost shifting. It also features a large upper pulley offset which automatically adjusts the chain gap. The roller bearing clutch technology reduces derailleur bounce & chain slap & cage lock technology makes wheel & chain installation & removals faster & simpler. Available in Black or Black/ Red.
