SRAM's X7 10-Speed Rear Derailleur provides precise, dependable shifting along with long-term durability. Its carbon and aluminum construction keep the weight down, while SRAM's 1:1 actuation ratio and direct cable routing provide quick, reliable shifts. Plus, this beauty is built to last so you can enjoy the trails for years to come.
An important part of a rear derailleur's job is keeping the chain taut as you change gears. Chain-wrap capacity is a number that tells whether or not a derailleur will be able to do this on the drivetrain you plan to use it on. Calculate chain-wrap capacity with this formula: Chain-wrap capacity = (large chainring - small chainring) + (large rear cog - small rear cog). Example: 46/34/24 chainrings and a 12-34 cassette: (46 - 24 = 22) + (34 - 12 = 22) = 44-tooth chain-wrap capacity.
Largest cog this derailleur handles: 36 tooth
