Why the Specialized Aethos?

In the realm of cycling enthusiasts, the appreciation for racing, the exhilaration of conquering Grand Tour summits, and the reverence for cycling classics like Monuments are deeply ingrained. Yet, there exists a profound understanding that sometimes, the act of riding for the sheer love of it, for the pure joy of cycling, is a necessity. This sentiment finds its embodiment in the Aethos.

The Aethos, a masterpiece that has not compromised on performance, proudly holds the distinction of being the lightest frame available. However, its significance transcends mere statistics—it seamlessly marries top-notch functionality with an uncompromising commitment to style. In the world of cycling, the Aethos stands as a symbol of relentless dedication.

Frame Sizing

The sizing chart is a great place to start when picking your next bike but everyone will fit a bike a bit differently. Your torso, arm, and leg lengths all play into what size of bike you may need. Plus, there's your own personal preference.

We always recommend swinging by the shop and taking the bike that you're looking for a spin to see how it feels. If you're unable to come by, looking at the geometry of your current bike and comparing it is a good place to start. If you have any further questions, our customer service team is there to help.
