Mechanical shifting at it’s best. Eagle 90 delivers the dream, and then some. Featuring the same Full Mount derailleur architecture as it’s AXS Transmission siblings, it is unquestionably robust. And for the just in case, the derailleur body features replaceable outer and inner parallelogram links, skid plates, and a tool-free threaded cage assembly, making it the most rebuildable derailleur we’ve ever built. At the heart of the system is a sleek and sturdy forged aluminum E-MTB crankset, with a drive-unit specific T-Type chainring. Shifting under load is a signature of Eagle Transmission, and this is made possible on 90 with an XS-1275 T-Type cassette that features full X-Sync technology, and a premium double-click T-Type Actuation mechanical shifter. For those inclined to DIY, mechanical Eagle Transmission has a revolutionary simple four step setup procedure: Prepare. Hang. Tighten. Route. Featuring no limit screws, no b-tension, and no guesswork. Built to take you as far as your imagination and body will allow, Eagle 90 Transmission provides riders with an unparalleled ride experience.
