Eagle 90 offers the best of mechanical shifting, realizing the dream and much more. With the same Full Mount derailleur architecture as its AXS Transmission siblings, it is undeniably robust. And just in case, the derailleur body features replaceable inner and outer parallelogram links, protection plates, and a tool-less threaded cage assembly, making it the most rebuildable derailleur we have ever built. At the heart of the system is a sleek and robust forged aluminum DUB bottom bracket, featuring a distinctive silver T-Type sprocket with removable fenders. Shifting under load is a hallmark of Eagle Transmission, and on the 90 it is made possible by an XS-1275 T-Type cassette with full X-Sync technology and a premium mechanical double-click T-Type Actuation shifter. For those inclined to DIY, the mechanical Eagle Transmission has a revolutionary simple four-step installation procedure: Prepare. Hang. Tighten. Route. No limit screws, no B-tension adjustment, and no guesswork. Built to take you as far as your imagination and body will allow, the Eagle 90 Transmission offers riders an unparalleled riding experience.

DUB™
The relationship between the bottom bracket spindle and the bottom bracket is the heart of DUB™ technology. It is where strength meets durability. We have moved beyond conventional thinking and made everything simpler, better integrating the relationship between the chainring, crank arm, spindle, and bottom bracket. It is this clear system approach that translates to better riding performance.
