Product Description


Exceptionally light, extremely well balanced, the Specialized Aethos Expert Disc Road Bike reinvents and perfects the ride. It's a bike engineered for pure enjoyment, delivering an unmatched ride quality through altered tube shapes, with a new layup creating stiffness and compliance, with no compromise on durability or weight. 

Shimano Ultegra Di2 11-speed components complement this frameset, keeping weight down and ensuring shifting is accurate and smooth. The reliable power of disc brakes inspires the confidence for speed across all parcours and in all conditions. Finished with DT Swiss R470 disc wheels, Specialized S-Works Turbo tyres and the incredibly light, highly adjustable Roval Alpinist carbon seatpost, this bike is the complete package.
