SRAM Eagle 90 T-Type Rear Derailleur - 12-Speed, Long Cage, 52t Max, Full Mount, Aluminum Cage, Black/Silver

This 12-speed rear derailleur from SRAM, the Eagle 90 T-Type (RD-90-A1), long cage, brings T-Type Transmission shifting to trail and enduro riders through a mechanical cable-actuated drivetrain. Full Mount hangerless design bolts straight to a UDH frame, which removes the derailleur hanger and holds alignment through impacts.

The long cage handles a 52-tooth max cog on 10-52t T-Type cassettes for wide climbing range. SRAM builds it to be rebuildable, with replaceable parallelogram links, skid plates, and a tool-free threaded cage, so a bent unit gets fixed instead of replaced. The aluminum cage keeps weight near 390 grams.

As the mechanical entry to Eagle T-Type Transmission, the Eagle 90 gives cable-shift riders UDH-mounted durability and 52-tooth range.
