Features specialized bike s-works aethos sram red axs 2025
The Aethos frame has been designed to achieve the perfect combination of riding feel, lightness and style. The Aethos is perfect: from its acceleration on steep slopes and its control on technical descents, to the best all-day comfort, even on the longest routes.
Reinventing the traditional road bike shape, we've subtly altered tube shapes to deliver huge gains in stiffness and balance, all without compromising weight or durability. Add to this a completely new lamination process that we have perfected for decades, and we have the lightest frame on the market (585 grams, S-Works, size 56cm). The Aethos is more than a new bike, it's the first in a new class.
As if that weren't enough, the lightest frame in the world is equipped with a complete Sram Red AXS with a power meter (the lightest electronic groupset ever) and the lightweight Roval Alpinist CLX II wheels, and the result is a perfectly balanced top-notch bike that gives up nothing in the name of performance.
