SPECIALIZED AETHOS PRO DISC ULTEGRA DI2 ROAD BIKE 2021

With the Specialized's Aethos Pro Disc Road Bike you get a combination of low weight, a balanced ride feel and sleek aesthetics, together with a Shimano Ultegra Di2 electronic groupset and Roval Alpinist CL wheels. The Aethos takes road bikes in a new direction, breaking the UCI rules and delivering a perfect ride. Engineered for the best possible ride feel and the lowest possible weight, the FACT 10r carbon layup has altered tube shapes for balanced stiffness, durability and sleek aesthetics.

Ultegra Di2 is Shimano's second-tier electronic groupset, bringing much the same performance as Dura-Ace with only a minimal weight penalty. Shifting is smooth and precise while the hydraulic braking is equally powerful on wet and dry roads. Rolling on gram-shaving Roval Alpinist CL wheels and Specialized S-Works Turbo tyres, strength and durability are balanced perfectly with sublime handling and a smooth feel. The finishing kit is equally as impressive, made up of the super-light Roval Alpinist carbon seatpost, Pro SL stem and S-Works Short & Shallow handlebar.
