The Aethos 2 was born from breaking the rules of racing to make every ride pure joy. It’s quick, smooth, and feels like it disappears beneath you. With more tire clearance, refined components, and updated geometry built from real-world rider data, it delivers that unreal ride feel to more riders than ever. The Aethos 2 doesn’t follow the rules: it rewrites them, all for the love of the ride.

The refined geometry gives you sharper handling, better control, and all-day comfort so you can climb faster, descend harder, and ride longer with total confidence.
