The Aethos line promises exceptional light weight, perfectly-balanced ride characteristics, and undeniable style.

This Aethos Pro is no exception, designed with billions of calculations in the pursuit of the perfect ride. The Aethos frame combines ultimate ride feel, light weight, and style, making it ideal for steep pitches, technical descents, and all-day comfort on long rides.

By reinventing the traditional road shape, massive gains in stiffness and balance are achieved without affecting weight or durability. An entirely new layup and process perfected over decades results in the lightest frame available. The Aethos is more than just a new bike; it’s the first of a new breed.

The Aethos offers a perfect balance of front and rear stiffness with exceptional ride quality. Groundbreaking findings on carbon fiber flexing and breathing have set a new standard for sublime rides. Every detail, from derailleur hangers to the fork expander plug, is designed with style, weight, and durability in mind.

Features:

  • Shimano's Ultegra Di2 for clean, crisp shifts.
  • Roval’s Alpinist wheels with DT Swiss 350 hubs.
  • New Alpinist carbon seatpost and wheels for weight savings.
