Details
SRAM's X7 Rear Derailleur offers an ideal combination of fluid shifting and durability. Its slim profile 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 can handle: 36 tooth
Weight: 225 grams
