Specialized Aethos Pro Di2

The Aethos is designed specifically for the pure experience of road riding rather than racing aerodynamics. It prioritizes an exceptionally lightweight frame and a balanced, supple ride quality over the aero-focused tube shapes found on the Tarmac, making it ideal for long days in the saddle.

Yes, the bike is equipped with Roval Alpinist CL II carbon wheels and S-Works Turbo TLR tires, both of which are tubeless-ready. You will just need to add sealant and valves if you choose to run a tubeless setup.

The Aethos frame is designed to accommodate tires up to 32mm wide. This allows for a bit more versatility and comfort on rougher pavement compared to traditional race bikes.

The Roval Alpinist Cockpit is a one-piece integrated bar and stem system, which offers a clean aesthetic and weight savings but limits independent adjustment. You can adjust the angle slightly by rotating the bar, but you cannot change the stem length or bar width without replacing the entire unit.

The Aethos features a performance endurance geometry that is slightly more upright than a pure crit-racing bike like the Tarmac. It is designed to be comfortable for long-distance riding while still maintaining a responsive and agile handling feel.

No, the Aethos utilizes a standard threaded BSA bottom bracket. This is a significant benefit for long-term maintenance and reliability, as it is easier to service and less prone to creaking than press-fit alternatives.
