The X1 11-Speed Rear Derailleur
- Type 2.1 from SRAM has been engineered in Germany for every rider & every trail. The Type 2.1 now features an internal change to the clutch mechanism which improves performance & longevity compared to the previous Type 2. Every detail of the X1 11-speed derailleur has been engineered for smooth, reliable shifting action from the larger upper pulley offset to the 12-tooth X-Sync pulley wheels. By eliminating unwanted chain movement, X-Horizon shifts faster, more smoothly & puts an end to ghost shifting. This reduced chain shift force & chain slap means you can have more confidence in your shifting no matter where you are. The sealed cartridge bearings allow everything to keep running smoothly & the cage lock technology makes wheel & chain removals & installations faster & more simple. Available in Black only.
