Specialized Aethos Pro

The Aethos is engineered specifically for ride quality and weight reduction rather than pure aerodynamic efficiency. While it is incredibly fast, its geometry and frame compliance are tuned to provide a more supple, comfortable experience for long days in the saddle compared to the aggressive, stiff nature of a race-focused bike.

Absolutely. With a frame weight of just 705g and a total bike weight of 6.73kg, this is one of the lightest production road bikes available. It excels on steep gradients and long ascents where low weight provides a distinct mechanical advantage.

The Aethos 2 is designed with increased tire clearance to accommodate tires up to 32mm wide. This allows you to run slightly wider rubber for improved comfort and traction on rougher tarmac without sacrificing the bike's nimble handling.

The integrated cockpit offers a clean, streamlined aesthetic, but it does limit traditional adjustability compared to a separate bar and stem setup. You can adjust the stack height using spacers, but changing the stem length or bar width will require swapping the entire unit.

The 12-speed Ultegra Di2 system provides near-instant, precise gear changes with minimal effort. It is highly reliable and requires very little maintenance compared to mechanical groupsets, making it an excellent choice for consistent, high-performance riding.

Yes, the bike comes equipped with the Roval Alpinist CL II carbon wheelset and S-Works Turbo TLR tires, which are tubeless-ready. Setting them up tubeless is highly recommended to take full advantage of the improved puncture protection and lower rolling resistance.
