What if we used all our accumulated experience from the last 46 years in the service of riders to build a racing bike that serves only the love of riding? The design of the Aethos masters the balance of perfect ride quality, extremely low weight, and undeniable style. And the Aethos Comp is no exception. With Shimano's electronic 105 Di2 shifting and hydraulic disc brakes, paired with the robust DT Swiss R470 Disc wheelset, you have the perfect buddy for any road ride.
