The S-Works Aethos 2 redefines what a high-performance road bike can be, prioritizing the pure joy of riding over rigid racing regulations. Weighing in as the lightest production road frame in the world at a staggering 595 grams, this machine is engineered to completely disappear beneath you on the tarmac. Specialized has achieved an optimal balance of responsiveness and compliance by utilizing their premier FACT 12r carbon and Rider First Engineered geometry, ensuring that every size delivers the same sublime, transcendent ride quality. Optimized for those who demand the absolute pinnacle of cycling innovation, this bike is not just about shaving grams; it is about delivering an unforgettable, telepathic connection to the road.
Every single component on this build has been meticulously selected to complement its groundbreaking frame. The drivetrain features the ultra-premium SRAM RED AXS E1 twelve-speed groupset, complete with an integrated Quarq power meter for flawless data tracking and crisp, wireless shifting. The rolling stock is equally impressive, featuring the aerodynamic Roval Rapide CLX III tubeless carbon wheels laced with innovative composite aero spokes, which strike a perfect balance between wind-cheating speed and featherweight climbing agility. Upgraded with a Ceramic Speed bottom bracket and headset bearings, as well as an integrated Roval Alpinist Cockpit II, the Aethos 2 ensures that friction is minimized and power transfer is absolute.
Beyond its breathtaking speed and featherweight build, this iteration introduces crucial modern refinements that elevate your daily riding experience. Increased tyre clearance allows for the inclusion of premium thirty-millimetre Cotton tubeless-ready tyres, providing exceptional grip and a supple, vibration-dampening ride without sacrificing raw speed. Cyclists will also benefit from the legendary S-Works Power saddle with Mirror technology, which uses a 3D-printed liquid polymer to perfectly support your anatomy and eliminate pressure points during all-day epics. With hidden cable routing providing a beautifully clean aesthetic and a standard threaded bottom bracket ensuring easy maintenance, this bike represents the ultimate investment for discerning riders who refuse to compromise on comfort, speed, or soul.

Founded in California in 1974, Specialized began with a simple promise: serious riders deserve serious gear. Half a century later, the brand still funds its own wind tunnel, builds its own carbon, and tests every bike with the world's best so that you ride your own best.
The first production mountain bike. The first cycling-specific shoes. FACT carbon, the Win Tunnel, S-Works. Specialized has a habit of building the things the rest of cycling ends up copying.
