Specialized Aethos Expert

The Aethos prioritizes ride quality and weight over aerodynamic optimization. While the Tarmac is designed to cheat the wind for pure speed, the Aethos is engineered for a lively, connected feel that excels on long climbs and winding descents.

Yes, the frame offers clearance for tires up to 35mm wide. This allows you to run slightly wider rubber for improved comfort and traction on broken pavement or light gravel sections.

Not at all. The electronic shifting is highly reliable and requires very little adjustment once set up. The system is sealed against the elements, and the battery life is extensive, typically lasting hundreds of miles between charges.

Yes, the Roval C38 carbon wheels are tubeless-compatible. Converting to a tubeless setup is a great way to reduce the risk of flats and run lower tire pressures for a smoother ride.

Absolutely. The Aethos features endurance-focused geometry that balances a responsive ride with stability, making it comfortable for all-day rides without sacrificing the performance characteristics of a high-end road bike.

With a 12-speed Shimano Ultegra Di2 drivetrain and a 30-tooth largest rear cog, the bike provides a versatile range of gears. It is well-suited for steep gradients, offering enough low-end range to keep your cadence efficient on challenging climbs.
