Specialized Aethos Pro eTap AXS Disc Road Bike
Blending low weight, pedalling efficiency, comfort and traditional aesthetics, the Specialized Aethos Pro eTap AXS Disc Road Bike offers an inspirational quality, heightening the enjoyment of any ride. The conventional, round frame tube sections are realised in a sophisticated layup of FACT 10r carbon to realise a lofty stiffness to weight ratio and excellent vertical compliance. The frame's rigidity and comfort are perfectly balanced across the front and rear of the design, regardless of the frame size, to elicit a reactive and composed ride sensation.
Frameset-to-tyre clearance for up to 32mm tyres affords the opportunity of extra plushness over extremely rough road surfaces, while a geometry borrowed from the brand's Tarmac SL7 race bike positions the rider powerfully and efficiently over the drivetrain. The drivetrain comprises SRAM Force eTap AXS 12-speed components that shift with precision and reliability via their wireless electronic configuration. Additionally, this drivetrain incorporates a power meter into its chainset, allowing accurate tracking of training and Strava KOM attempts.
Roval Alpinist CL wheels are light and nimble performers, increasing the bike's speed on steep climbs and sinuous descents. These wheels are stopped by the hydraulic disc brakes, which inspire confidence in all weather conditions thanks to their powerful and controlled actuation.
