This SRAM Red is a complete cable-actuated 10-speed rear derailleur with carbon and aluminum construction, ceramic-bearing pulleys and titanium hardware. It uses SRAM’s Exact Actuation system.
The short-cage selection lists a 28T maximum sprocket. Check the matching drivetrain and total-capacity requirements; the 32T maximum and 151g medium-cage measurement describe a different option. This is not a spare cage or an AXS electronic model.
