SRAM Eagle 90 Transmission Rear Derailleur

The SRAM Eagle 90 Transmission Rear Derailleur brings the precision and reliability of T-Type shifting to a cable-actuated setup. The cage is made with lightweight and durable aluminum. With a new cable actuation ratio tuned specifically for crisp, consistent shifts, it delivers a high-performance experience backed by the same robust Full Mount design used across the Transmission range. The derailleur features replaceable skid plates, a serviceable outer parallelogram link, and rebuildable cage options for long-term durability. A new Drag Spring damper adds chain control to make the SRAM Eagle 70 Rear Derailleur an affordable piece to a performance groupset.
