The SRAM Eagle 90 Transmission (T-Type) groupset is the pinnacle of off-road drivetrain technology, designed as a holistic, integrated system for the most demanding riders. This pre-packed kit removes the guesswork by providing a perfectly matched derailleur, cassette, chain, shifter, and crankset, all engineered to deliver seamless shifting under maximum load.
Hangerless Interface: The T-Type derailleur mounts directly around the wheel axle, creating a far stronger connection and eliminating the need for a traditional derailleur hanger for more precise shifting.
Full-Load Shifting: Utilises advanced mapping on the cassette and chain to allow for crisp, instantaneous shifts even when you are pedaling at full power during steep climbs or sprints.
T-Type Flattop Chain: Features a unique flat-top profile specifically engineered to handle the higher torque loads of modern mountain biking while increasing overall chain life and strength.
Magic Wheel Pulley: The derailleur’s oversized lower pulley wheel is designed to keep spinning even if a stick or debris becomes lodged in it, preventing drivetrain catastrophic failure.
AXS Wireless Ecosystem: Provides a clean, cable-free cockpit with customisable shift logic and battery monitoring through the SRAM AXS mobile app.
Optimised Q-Factor Crankset: The included crankset is forged for maximum stiffness-to-weight ratio, featuring a chainline designed specifically for the latest generation of wide-spaced frames.

✅ Zero-Compromise Performance: Ideal for racers and enthusiasts who want the most durable and reliable wireless shifting system ever created.
✅ Simple Setup: The hangerless design eliminates the need for B-gap or limit screw adjustments, making initial installation and long-term maintenance incredibly easy.
✅ Unrivalled Durability: Built to take hits; the direct-mount interface is significantly more resistant to impact damage than traditional derailleur setups.
❌ Frame Compatibility: Your frame MUST be UDH (Universal Derailleur Hanger) compatible to mount this specific T-Type transmission system.
❌ System Ecosystem: T-Type components are specifically designed to work together; you cannot mix and match these with older Eagle AXS chains or cassettes.
When setting up your Eagle 90 Groupset, ensure you use the SRAM AXS App to check for firmware updates immediately. The app also allows you to customise the "Multishift" function—we recommend setting it to a 2 or 3-gear max to prevent accidental over-shifting in technical terrain. Because this system shifts best under load, don't be afraid to click through the gears while you're grinding up a hill; unlike older drivetrains, this one actually prefers it!
