Eagle 90 T-Type 12-Speed Mechanical Rear Derailleur

What Our Gearhead® Experts Are Saying:

"The Eagle 90 T-Type derailleur sets a new standard for mechanical shifting. With its Full Mount design, shifting is ultra-crisp and precise, even under maximum pedaling power. I love that it’s fully rebuildable, so I can replace key components instead of the whole derailleur. Whether I’m racing or shredding technical descents, this derailleur keeps my drivetrain feeling dialed."

Built for riders who demand the best, the Eagle 90 T-Type 12-Speed Mechanical Rear Derailleur delivers elite-level performance with the most precise mechanical shifting SRAM has ever produced. The Full Mount attachment eliminates the need for a traditional hanger, providing increased durability and shift accuracy across all frame designs.

Designed for relentless trail and enduro riding, this derailleur features a completely rebuildable construction with replaceable skid plates, parallelogram links, and a tool-free threaded cage assembly. The T-Type cable actuation ensures crisp, reliable shifts under full pedaling power, making it the ideal choice for aggressive riders who want the best mechanical shifting on the market.
