Sram RED XPLR eTap AXS D1 Rear Derailleur RD8157000

SRAM RED XPLR eTap AXS D1 Rear Derailleur Sitting at the top of SRAM’s XPLR range, this RED eTap AXS D1 rear derailleur features an all-new B-knuckle design that has been conceived to perform with wider-ranging 12-speed gravel riding cassettes within a 1x chainring format. Incorporating wireless electronic AXS eTap shifting, smooth gear changes across cassettes with ranges as large as 10-44T are guaranteed. Additionally, the AXS system allows gear shift patterns to be fully customised via the dedicated app and promises easy setup and installation. Orbit clutch technology sharpens gear actuation, quietens the drivetrain and cancels chain bounce without increasing drivetrain resistance, while the larger X-Sync pulleys heighten durability and efficiency. Powered by the same battery (available separately) as all the other derailleurs in the eTap family, interchangeability is guaranteed. Please note, the eTap battery isn’t included and will need to be purchased separately.
