Mechanical shifting at its best. The Eagle 90 is a dream come true and so much more. It features the same Full Mount derailleur architecture as its AXS Transmission siblings, making it undeniably robust. In case of emergencies, the outer and inner parallelogram links, skid plates, and the tool-free removable derailleur cage assembly can be replaced on the derailleur body. This makes it the most repairable derailleur we've ever built. A core element of the system is the sleek and sturdy DUB crankset made from forged aluminum, featuring its T-Type chainring in Signature Silver and interchangeable bash guards. Shifting under load is a hallmark of the Eagle Transmission, and this is enabled in the 90 model with an XS-1275 T-Type cassette, which includes the complete X-Sync technology and a premium mechanical T-Type actuation shifter with double-click functionality. For those who enjoy working on their bikes, the Eagle Transmission can be installed in a revolutionary simple setup process consisting of just four steps: Prepare, Attach, Tighten, and Route the shift cable and housing. It operates without limit screws, no screw for the wrap angle, or any other guessing. Built to take you as far as your imagination and body allow, the Eagle 90 Transmission offers the rider an unparalleled experience.
