Trickle down bike-onimics is real, and the SRAM Apex XPLR AXS 12-Speed Rear Derailleur proves it. This electronic marvel fits wide-range cassettes with 36T or 44T large cogs and incorporates a spring clutch for superior chain management on or off-road. It features SRAMs impressive eTap shift logic and AXS connectivity for flawless bzzt bzzt shifting.
AXS – Wireless electronic eTap shift logic for intuitive shifting, easy personalization, and reliability.
Cage Lock™ – With Cage Lock™ technology in the rear derailleur, wheel removal and installation—as well as chain installation—becomes faster and simpler. Just pushing the cage forward to create slack and lock it into place.
X-Sync™ – SRAM X-Sync™ 1x chain rings provide the highest level of performance and durability. The SRAM X-SYNC™ tall square teeth edges engage the chain earlier than traditional triangle shaped teeth. The sharp and narrow tooth profile, as well as rounded chamfer edges, help manage a deflected chain. To provide the best possible performance in muddy conditions, the X-SYNC™ chain rings have been designed with mud-clearing recesses for the inner chain links and rollers. Engineered in Germany, X-SYNC™ rings are an integral part of the SRAM 1x™ drivetrain.
eTap – Get wireless shifting and advanced battery power management for the most intuitive and consistent shifting available.
Compatibility – 1x specific for use with 11-44 T XPLR, 10-44T XPLR, and 10-36T cassettes.
