Sram Eagle 90 Groupset 12V 34T 104mm 10-52T - Black

Mechanical shifting at its best.
SRAM Eagle 90 delivers the dream, and then some.
Featuring the same Full Mount derailleur architecture as its AXS Transmission siblings, it is unquestionably robust.
And for 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 SRAM has ever built.
104mm bolt circle diameter variant without crank arms for compatibility with all other drive unit manufacturers.

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 dedicated single-click mechanical shifter for E-MTB use.
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.
