It’s the best of SRAM's road and mountain bike innovations in one package.Compatible with 50t and 52t Eagle cassettes. Works with SRAM 12-speed mechanical Apex and Eagle shifters. For use with Eagle 12-Speed chain. Roller Bearing Clutch controls chain tension for consistent shifting. X-HORIZON straight parallelogram design limits all movement to the horizontal axis, which makes ghost shifting impossible while also reducing shift force.
