Specialized Aethos

The Aethos is Specialized's ultralight climbing platform, engineered to sub-6kg complete bike weight at S-Works spec. The frame uses a unique carbon tube-to-tube construction method that differs from standard monocoque layup. It is a bike built specifically for riders who want the lightest possible road platform for climbing. Bikeroom carries new and pre-owned Aethos builds across S-Works, Expert, and Comp trim levels with full spec and condition documented in every listing.
