I am a 61yo male who now rides recreationally at 6-8,000miles per year. Preferred courses are hilly. In the last 15 or so years have had a Cervelo R3 SL, a Cervelo R5, a Trek Emonda SL and a BMC Roadmachine (my current other road bike). I have also rented a number of different Specialized, Trek, and Pinarello road bikes. Aero frames are of little interest to me. I was intrigued by the Aethos and opted to take the plunge on an S-Works Aethos frame. Built it up with Dura-Ace Di2/hydraulic, Hunt wheels with 28mm Schwalbe Tubeless tires. Have now been riding it for 8+ months with a few thousand miles on it, alternating some with the BMC. Gotta say, this bike's ride is absolutely phenomenal - solid and confidence inspiring on all terrains, especially hilly ones. The other thing is I just love it's understated looks - rode a century and no-one knew what it was! Perfect! Easily my favorite ever ride - The Aethos just makes me smile every time I ride it!
