If you're looking for beefy stealth, consider the XX front derailleur which shifts across the entire gearing range with near nil chain rub and a granny gear that can be cross-chained within one or two cogs without cage rub.
Leveraging the legendary history of SRAM shifting, the XX Rear derailleur delivers incredible speed and precision. Sealed ceramic pulleys give you the highest levels of durability, while Exact Actuation technology eliminates slop and shifting variation.
Two cassettes enter, one cassette leaves as the evolutionary XX 10-Speed cassette takes center stage with its incredibly lightweight status, precise shifting abilities, and superior Thunderdome-worthy strength. X-Dome CNC-machines together eight cogs from a single block of billet steel.
No weakest link here! The super narrow Sram PC 1091R 10-speed PowerChain features a PowerLock connecting link - the only secure tool-less attachment device in today's market. The chain's HollowPin construction provides smooth, precise shifting and weight savings without sacrificing strength. Other features include heavily chamfered outer plates for improved shifting, and a new inner plate finish, plus chrome hardened pin construction, for increased chain life.
