SRAM Force 1 Rear Derailleur Long Cage (10-42) T3

Simplify your ride with the SRAM Force 1 Rear Derailleur Long Cage (10-42) T3. Sharing all the same features that made SRAM's mountain bike lineup so popular, this rear derailleur brings the fastest and quietest possible shifting to the 1x road market.

Featuring SRAM's Roller Bearing Clutch, chain tension is maintained for consistent shifting in all conditions, while the 12 tooth X-SYNC pulley further improves the ride quality, helping to control the lateral movement of the chain. Similarly, the intuitive X-HORIZON design virtually eliminates horizontal movement, reducing the force required to shift and the chances of ghost shifting greatly.

The addition of SRAM's tried and tested Cage Lock system speeds up wheel changes, perfect for the demands of cyclocross racing and roadside repairs alike. Compatible with cassettes ranging from 11-32t through to 10-42t, this lightweight derailleur makes the perfect addition to any high spec road or gravel machine.
