The X01DH 10-Speed Rear Derailleur
- Type 2.1 from SRAM delivers quicker shifting, smarter gear steps, & more precise chain management, making shifting smooth & reliable no matter where you ride. The Type 2.1 now features an internal change to the clutch mechanism which improves performance & longevity compared to the previous Type 2. Engineered to maintain consistent chain gap across all ten gears, X-Horizon eliminates vertical movement for faster shifting, reduced shift force & an end to ghost shifting. The roller bearing clutch technology & the 12-tooth X-Sync pulley wheels hold the chain in place, reducing derailleur bounce & chain slap. The cage lock technology means wheel & chain removal & installations are faster & simpler. Available in Black or Black/ Red with either Medium or Small cages.
