The Aethos 2 Pro Shimano Ultegra Di2 is built for serious road riders and racers who want the lightest, most integrated bike possible — training for climbs like Myra Canyon or racing valley gran fondos with real power data at their fingertips. It suits cyclists who already train with power and want an aero-integrated cockpit and top-tier componentry, not a first road bike.

Getting your Aethos 2 Pro dialled in starts with proper fit — our team will set your saddle height, fore-aft position, and integrated cockpit reach to match your riding style, and can help with cleat alignment if you're running clipless pedals. We'll also pair your 4iiii power meter to your head unit or app, and set tire pressure appropriate for the tubeless-ready S-Works Turbo TLR tyres based on your weight and the roads you're riding.
