This 10-speed MTB rear derailleur is built around SRAM’s Exact Actuation shifting system, giving you precise indexing with a straightforward setup. The short cage is suited to compatible 10-speed drivetrains using 1x, 2x or 3x configurations, with a published maximum cassette size of 36T.
SRAM’s Type 2.1 package combines Roller Bearing Clutch and Cage Lock technology. The clutch helps reduce derailleur movement, chain bounce and chain slap on uneven trails, while Cage Lock lets you push the cage forward and hold it in place for easier chain fitting and wheel removal. Direct Route cable routing is designed to reduce friction and shifting effort.
With an aluminium cage, steel pulley bearings and a black finish, this is a sensible choice when you need reliable SRAM 10-speed replacement performance without moving to a newer drivetrain standard. For compatibility, match it with an Exact Actuation 10-speed shifter and a compatible cassette within the published 26T, 28T or 36T minimum options and 36T maximum.
A good fit for riders restoring or maintaining a SRAM Exact Actuation 10-speed MTB drivetrain who want clutch-equipped shifting and a short-cage derailleur.
