Let's talk latest technology

All trails. All day.

GX Eagle Transmission is ready to go toe to toe with anything, perfect shifting that’s unapologetically robust. It’s simply the most dependable drivetrain we’ve ever created, built to hold its own on any trail and outlast the rest, even with the added power of a motor. GX Eagle Transmission is even rebuildable to keep working season after season. Forget the old excuses, this is the new people’s champion for all-in, all-day rides.

We’ve leveraged the insanely secure connection of the Hangerless Interface to protect the AXS battery on GX Eagle Transmission derailleurs. Where the Full Mount attachments sandwich the frame, we’ve tucked the battery mount out of harm’s way to keep rides flowing.

GX is legendary among trail riders for its all-day reliability. By eliminating unnecessary parts and removing typical failure points, GX Eagle Transmission steps forward into a new dimension of dependability. Hangerless Interface centers the entire drivetrain around the rear axle, delivering never-before-realized strength for both the frame and derailleur. To absorb typical trail impacts, the Overload Clutch instantly disengages the derailleur’s motor; in the event the rock wins, a simple Trailside Reset is as easy as pulling the derailleur back into place by hand. Worry less, rip harder.

Ride after ride, the hard-wearing GX Eagle T-Type cassette is always ready for more. The X-Sync tooth profile keeps the chain and cassette engaged throughout the shift, reducing wear on individual cassette teeth and chain links for radically improved longevity. Even with the added watts of E-MTB, the precision synchronization of Cassette Mapping gives you the power to shift when you want. This is the hardest working drivetrain for the hardest charging riders.
