Description

When you are riding the lightest production frame ever made, it is only natural you select a build featuring the superb, partially wireless Dura-Ace Di2, to complement it. The S-Works Aethos frame weighs just 585 grams and built here in a complete package with Shimano Dura-Ace Di2 shifting and Roval Alpinist CLX disc brake wheels it results in a sub 14lb build that is fully capable for all the requirements of road cycling, even racing. Of course you'd need to load up on lead weights, as it sits well below the UCI weight limit. And although the S-Works Aethos carries a race geometry, it was engineered and developed to offer the apex cycling experience for the serious enthusiast who appreciates the ultimate in quality and design.

The story of the Aethos is pure Specialized. The achievement of the frameset design represents virtually all of the foundational principles of the company, except one. For one of the leading proponents of aerodynamic design for road cycling and racing, as exemplified by the Tarmac SL7, aerodynamics was never factored in to the development of the Aethos. The engineering problem of building the lightest, most exceptional riding road bike was incredibly appealing. Having solved unbelievably complicated problems with the SL7, they may not have anticipated new and more efficient applications of carbon fiber, or that as a result they'd discover a Continuous Curvature Design strategy. The end result of Aethos process pushed the most innovative team in cycling development to new heights.

The Aethos frame has been designed with the perfect combination of ultimate ride feel, light weight, and style. This was achieved by reinventing the traditional road tube shapes found on bikes of the past, subtly altering these visual shapes to deliver massive gains in stiffness and balance, all without affecting weight or durability. That visual story appears simple on some level, but it was the application of carbon technology and incredible engineering capabilities to find the stress loads, tube thicknesses, and how to best integrate all of the shapes and engineering requirements in ways you can't see to create the Aethos. This new process, with an entirely-new layup system tapped into the R&D system Specialized has perfected over multiple decades.... Read More
