The Specialized Aethos Road Bike: Engineering the Perfect Ride

The Specialized Aethos Road Bike was purely designed to create the perfect ride for you. This philosophy drives every aspect of the Aethos, which masterfully blends ride quality, ultra-lightweight design, and striking style. The Aethos Expert model exemplifies this commitment to excellence.

Equipped with cutting-edge features like wireless SRAM Rival eTap AXS electronic shifting and powerful hydraulic disc brakes, the Aethos ensures precision and reliability on every ride. Paired with robust Roval C38 Disc carbon wheels, this bike is engineered to perform on any road.

  • Revolutionary Frame Design: The Aethos frame strikes the ideal balance between ride feel, lightweight construction, and aesthetic appeal. By reimagining traditional road bike geometry, Specialized have enhanced stiffness and balance while maintaining minimal weight and top-tier durability. The result is the lightest frame in its class, just 585g for the S-Works size 56cm.
  • Optimal Ride Quality: The Aethos is designed to excel in every situation, whether you're powering up steep climbs, navigating technical descents, or enjoying long, comfortable rides. Through decades of refining carbon fibre technology, Specialized have achieved groundbreaking stiffness and balance that elevates your riding experience.
  • Precision Engineering: Every detail of the Aethos, from the derailleur hangers to the fork expander plug, has been meticulously crafted with a focus on style, weight, and durability. The inclusion of the all-new Roval Alpinist carbon seatpost further reduces weight and enhances ride quality.
  • A New Standard in Performance: The Aethos sets a new benchmark for road bikes by seamlessly combining lightweight engineering with confidence-inspiring ride characteristics. Extensive research into how carbon fibre flexes and breathes has allowed Specialized to unlock new levels of performance.

The Specialized Aethos isn't just a bike, it's the beginning of a new era in road cycling, where every element is optimised for the ultimate ride. From its featherweight frame to its perfectly balanced stiffness, the Aethos redefines what's possible on two wheels.
