SRAM Eagle 90 DUB Groupset EMTB BOSCH

Featuring SRAM’s innovative Full Mount derailleur architecture, the Eagle 90 groupset ditches the traditional hanger in favour of a stronger, more consistent interface. The result? A rock-solid connection and the most rebuildable derailleur SRAM has ever built. With replaceable links, skid plates and a tool-free cage assembly, it’s designed to handle serious trail abuse—and keep coming back for more. At its heart is a forged aluminium crankset built specifically for Bosch E-MTB drive units, with a seamless “Gap Cap” design and a tough clip-on guard. Riders get the choice of 160mm, 165mm, or 170mm crank arm lengths, or opt for a 34T 104BCD variant to suit other drive units. Paired with an XS-1275 cassette (10-52T) using SRAM’s X-SYNC technology, you can shift smoothly and precisely even when putting down serious power. The mechanical shifter comes with stealth cable routing, ergonomic shaping, and a premium textured aluminium lever. For E-MTB use, the Eagle 90 is fitted with a mandatory single-click variant to manage extra wattage safely. There’s even a shift housing/brake hose clip to help keep your cockpit clean and organised. Set-up is refreshingly simple: just prepare, hang, tighten and route—no limit screws, no b-tension, no guesswork. Whether you’re upgrading or building, the Eagle 90 makes mechanical shifting easy and accessible.
