Product Details
The SRAM Apex D1 Eagle 12-Speed Rear Derailleur brings together the best of SRAM’s road and mountain bike tech, offering fast, quiet, and consistent 12-speed shifting on even the roughest terrain. Designed to work seamlessly with SRAM's 12-speed mechanical Apex and Eagle shifters, it’s optimized for 1x drivetrains and Eagle cassettes up to 52T, giving you a huge gear range and smooth shifting performance whether you're grinding gravel or powering up steep climbs.
