Deliver The Dream.

Eagle Transmission drops a seismic shift on what it means to shift a mountain bike. Built around the universal constant of the wheel axle itself, Eagle Transmission is a radically robust, fully integrated and interdependent wireless transmission that literally changes how we ride. It simplifies, strengthens and extends lifespan to new limits. It uses no derailleur hanger or adjustment screws and lets you shift flawlessly under maximum power. Welcome to the dream made real.

Enabling Nirvana.

Full Mount / T-Type

Utilizing the widely adopted frame design required for the Universal Derailleur Hanger, the Hangerless Interface allows Eagle Transmission to work around the one universal constant – the center of the rear axle. This opens up the possibility for perfect shifting, eliminates unnecessary parts and allows all other features to work in perfect relationship to this constant.

Impossible until now

Sophisticated Synchronization.

With the introduction of X-Sync technology on the cassette and retimed shift routes - Cassette Mapping is a marriage of firmware and hardware that makes it possible to control the shift, under any load. When a shift is made, the derailleur’s firmware references a uniquely timed shift sequence to align with the releasing/receiving cogs - engaging chain rollers on the desired cassette teeth. This creates continuous chain engagement for pure uninterrupted power transfer. With over 44 shifting points across the gear range, strategically located based on common cassette speeds, Cassette Mapping increases shift precision and ensures constant load transfer.

Prepare. Hang. Tighten.

The entire setup procedure is completed in just three simple steps - with no special tools - and takes about two minutes total. Setup for Eagle Transmission is unlike any drivetrain that’s come before. Just follow the steps and get out there to ride like you’ve never ridden before.

Transcendent Toughness.

Because robustness starts with simplicity, Eagle Transmission has fewer parts and fewer variance for far greater reliability and toughness.

E-MTB in full sprint

You’re Not Dreaming.

Rebuild, replace, repeat.

Take a crash or slam into an immovable object with your Eagle Transmission derailleur, and there’s a better chance than ever that the only damage will be cosmetic. Which is why we’ve equipped all Eagle Transmission derailleurs with one or more replaceable Skid Plates.

Being able to rebuild your Eagle Transmission derailleur beyond the skid plate is also a reality. If needed, you can swap Full Mount, Inline Cage, Magic Wheel and more.

Realize Your Vision.

Welcome to infinite personalization.

Eagle Transmission AXS Pod Controllers are intuitive, discreet and programmable. Mount on the left or right to match your vibe. Which button shifts up, which one shifts down, which controls your Reverb dropper? It’s all up to you, just configure your way on the AXS app.

The Infinity Clamp gives you an infinite number of mounting configurations for ultimate freedom. With a flippable design and 360-degree adjustability at both the controller mount-point as well as at the handlebar. It’s thinner, more discreet, works independently of your brake lever, and offers a single bolt for further fine-tuning.
