Description
Specialized Aethos 2 Pro Carbon Road Bike 2027
The Aethos 2 represents a revolutionary approach to road cycling, intentionally breaking traditional racing design rules to focus entirely on the quality of your ride. At the heart of this machine is a remarkably lightweight 705-gram FACT 10r carbon frame, making it the lightest bike in its class while maintaining an incredibly responsive and supple feel. Specialized has utilized data-based, fit-enhancing geometry alongside Rider First Engineered technology to ensure that every frame size provides the exact same sublime, telepathic handling. Engineered to essentially disappear beneath you on the tarmac, this bike delivers pure riding bliss to cyclists who value a truly transcendent connection to the road.
Premium Componentry and Seamless Performance
Equipped with highly refined components, this build offers a premium mechanical package that perfectly complements its featherweight frame. Power delivery and shifting are managed by the precise SRAM Force AXS E1 twelve-speed wireless groupset, featuring an integrated Quarq power meter to help you track your performance metrics flawlessly. The rolling stock consists of Roval Rapide CL III tubeless carbon wheels with reliable DT350 hubs, offering an exceptional balance of aerodynamic efficiency in the wind and lightweight agility on the climbs. Combined with the lightweight Roval Alpinist Carbon seatpost and the fully integrated Roval Alpinist Cockpit II handlebar system, the bike ensures a sleek profile with hidden cable routing and maximum power transfer.
Modern Capability and Uncompromised Comfort
Designed with modern road riders in mind, this iteration brings upgraded clearance for wider tyres, coming stock with premium thirty-millimetre Cotton tubeless-ready tyres for unmatched grip and vibration damping. Comfort is further elevated by the inclusion of the Power Pro Mirror saddle, which uses innovative 3D-printed liquid polymer technology atop hollow titanium rails to relieve pressure points during long endurance days. With a standard threaded bottom bracket for hassle-free maintenance and a total weight of just 6.81 kilograms, this bike is an exceptional investment for discerning riders looking to elevate their everyday cycling experience without compromise.
