Product Details
The Aethos line promises three things: unprecedented weight savings, perfectly-balanced ride quality, and undeniable style. For the Aethos Pro we threw out the rulebook to create the ride of your life.
Spec’d with SRAM’s intuitive Force eTAP AXS electronic shifting to deliver clean, crisp shifts and Roval’s Alpinist wheels mated to DT Swiss 350 hubs. This is a no-fuss build that delivers, mile after mile.

- A featherweight frame is useless without confidence-inspiring ride characteristics, which is why we’ve developed the Aethos to have the perfect balance of front and rear stiffness combined with exceptional ride quality. By studying the flexing and breathing of carbon fiber, we were able to discover groundbreaking findings about how forces flow through frames. Just a few pedal strokes and you’ll realize this sublime ride sets a new standard.
- Every detail, from the derailleur hangers to the fork expander plug have been designed with style, weight, and durability in mind. We’ve also spec’d it with Roval’s all-new Alpinist carbon seatpost and wheels, further saving weight and improving ride characteristics. Everything in pursuit for the perfect ride.
