POWERFUL MECHANICAL PERFORMANCE, PRECISION & DURABILITY
The Eagle 90 Transmission redefines mechanical drivetrains by delivering the strongest shifting performance without the need for a battery. Fully integrated within the SRAM Transmission ecosystem, it allows riders to experience the latest drivetrain innovations while staying mechanical. Its unique Full Mount design provides extreme stability, while its fully rebuildable derailleur ensures long-term durability and serviceability.
RIDE. REBUILD. REPEAT.
The Eagle 90 Transmission derailleur is built to last. Unlike any other mechanical derailleur, every key component can be replaced - outer and inner parallelogram links, skid plates, B-knuckle, and even the tool-free removable cage. Whether it’s due to hard impact or regular wear, you can repair and maintain it yourself, keeping your drivetrain running for years and years.
TRANSMISSION-LEVEL SHIFTING
With its optimized T-Type cable actuation, the Eagle 90 delivers the crisp, powerful shifting performance of Transmission systems - without needing a battery. It maintains full compatibility with all T-Type components, ensuring easy integration and future-proof compatibility within the Transmission ecosystem, while adding the durability of mechanical shifting.
