SRAM 90

Eagle 90 Transmission is the world’s first mechanical groupset with Full-Mount toughness, rebuildable robustness and unprecedented sure-thing shifting under max power. With game-changing ease of set up and zero guesswork required, Eagle 90 is pretty much unstoppable. And proves the satisfying tactility of shifting mechanically is reimagined for the next era of MTB.

Even with the added watts of E-MTB, the X-Sync tooth profile and 44 specific shifting points on Eagle Transmission cassettes allow you to shift with unstoppable precision under all the power you can muster. It’s the best mechanical shift performance under load there is. It’s not even a contest.

The Eagle 90 Transmission derailleur is the absolute toughest you can find. Using a Full Mount attachment, there’s no derailleur hanger to bend or break, and everything is centered around the center of the axle itself. It’s precise, reliable, and literally strong enough to stand on without a whimper. In the event that it does take a crazy hard hit, it rotates out the way, ready for a quick Trailside Reset that will have you back shredding in seconds. This is what unstoppable on-trail performance is all about.
