Max Cog 42t Fully Compatible with All SRAM 1x(TM) Drivetrains X-Actuation(TM) Developed specifically for SRAM 1x(TM), X-ACTUATION(TM) keeps shifting sharp and consistent across the entire cassette. X-Horizon(TM) The X-HORIZON(TM) rear derailleur's 'straight parallelogram' design limits all movement to the horizontal axis, which makes ghost shifting impossible while also reducing shift force. For quicker, more exact shifting, the large upper pulley offset design maintains a constant chain gap across all gears. | SRAM NX 11-Speed Rear Derailleur 2022 - Long Cage
