Specialized Aethos Pro Ultegra Di2

Specialized Aethos Pro - Ultegra Di2 2021

With the Aethos Specialized aren't designing a bike for the pros, there's the amazing Tarmac for that. This bike is designed for us 'normal' riders. Sure it's UCI certified but this bike probably won't be seen with a yellow-jerseyed rider aboard. The Aethos is incredibly light at every price point (approx 699g 10r frame in 56cm). Weight isn't everything though so Specialized have used all their carbon knowledge to create a bike that feels like nothing else. Surely a bike you'll want to jump on time and time again, be it for a 1 hour blast when you're short on time or an all day epic. This bike is for the love of riding.

This bike comes with a pre-delivery inspection by our mechanic. Further details of our ex-demo, display and returned bikes can be found here.
