Eagle Mechanical Transmission redefines durability with its Full Mount derailleur interface, which eliminates hangers and provides an ultra-secure connection to the frame. This innovative design minimizes failure points and prevents misalignment, ensuring a rock-solid drivetrain even in the roughest conditions. The Eagle 90 derailleur is particularly sustainable, with replaceable skid plates and outer and inner parallelogram links, making it the most rebuildable mechanical derailleur available.

With the precision of X-Sync tooth profiles and 44 optimized shifting points, combined with the Full Mount interface, Eagle Mechanical Transmission delivers the best cable actuated shifting under load—whether you’re climbing, sprinting, or pushing an E-MTB to its limits. The Eagle Mechanical drivetrains maintain precise and crisp gear changes in all conditions, with T-Type cable actuation providing smooth engagement every time. Shifting under power has never been this good on a mechanical groupset.

Forget finicky adjustments—Eagle offers an incredibly simple “prepare, hang, tighten” installation. With no limit screws or B-tension to worry about, setup is foolproof and fast. Compared to AXS systems there is only one additional step required and that’s to simply route and tension a standard shift cable. The clearly marked Setup Cog on the cassette ensures alignment is quick and straightforward for all riders.

The Eagle 90 derailleur is designed to be the most rebuildable derailleur ever. Riders can replace key components like the B-Knuckle, P-Knuckle, skid plates, and even the cage assembly with simple tools. Rebuild kits are readily available, ensuring longevity and serviceability. With replaceable bushings and pulleys, Eagle 90 minimizes downtime, allowing riders to repair rather than replace, keeping their drivetrain running smoothly for years to come.

As part of the Eagle Transmission ecosystem, all Eagle Mechanical components are fully compatible with other T-Type parts, whether electronic or mechanical. This allows riders to mix and match components while ensuring seamless performance across the board. The hangerless Full Mount design is exclusive to UDH-compatible frames, eliminating inconsistencies across different bike manufacturers and ensuring precise, reliable shifting in any setup.
