Aethos Sport Shimano 105 Specialized 2025 Satin Metallic Spruce

AETHOS SPORT SHIMANO 105

What if we used every gram of experience we've gained serving cyclists over the past 46 years to build a bike made simply for the love of cycling? The Aethos is designed to perfectly balance ride quality, extreme lightness, and undeniable style. The Aethos Sport model is no exception.

With a low-maintenance Shimano 105 mechanical groupset and hydraulic disc brakes, combined with all-terrain DT Swiss R470 Disc wheels, you have the perfect companion to get excited on the road.

• The Aethos frame has been designed with the perfect combination of ride feel, lightness, and style. From steep climbs and technical descents to all-day comfort on the longest routes, the Aethos delivers. But how did we achieve this? By reinventing the traditional shapes of past road bikes, we’ve subtly modified these forms to achieve massive improvements in stiffness and balance without affecting weight or durability. Combine this with a new lamination and process we've perfected over decades, and you get the lightest frame on the market (585 grams, S-Works, size 56 cm). The Aethos isn’t just a new bike, it’s the first of a new generation.

• An ultralight frame is useless without ride characteristics that inspire confidence, which is why we’ve developed the Aethos with the perfect balance of front and rear stiffness, combined with exceptional ride quality. By studying the flex and breathing of carbon fiber, we made revolutionary discoveries about how forces are distributed through the frame. A few pedal strokes are all it takes to realize that this sublime ride sets a new standard.

• Every detail, from the derailleur hangers to the fork expander, has been designed with style, weight, and durability in mind. We've also equipped it with the new Roval Alpinist carbon seatpost, which saves weight and further improves ride quality. All in the pursuit of the perfect ride.
