SRAM XX1 11-Speed Rear Derailleur – Type 2.1 – N/A
The XX1 11-Speed Rear Derailleur – Type 2. 1 from SRAM was built with a dedicated 1X drivetrain philosophy, making it simpler, lighter and more durable. The Type 2. 1 now features an internal change to the clutch mechanism which improves performance and longevity compared to the previous Type 2. It uses X-Horizon's horizontal parallelogram design and pulley offset to keep the chain gap constant across all 11 gears, providing fast and precise shifts. By limiting all movement to the horizontal axis, this design is faster, reduces shift force and eliminates ghost shifting. The roller bearing clutch technology reduces bounce and chain slap and the cage lock technology makes wheel and chain removal and installation faster and simpler. The derailleur has 12-tooth X-Sync pulley wheels with a large upper pulley offset which automatically adjusts the chain gap for smoother running. Available in Silver/Black/Red in one size.
