The Specialized Aethos Road Bike: Engineering the Perfect Ride with a groupset that Rivals the best.

The Specialized Aethos Expert Rival eTap AXS Road Bike is a premium lightweight carbon road bike built for riders who demand exceptional ride quality, climbing efficiency, and precision handling. Combining ultra-lightweight frame design, wireless SRAM Rival eTap AXS electronic shifting, and hydraulic disc brakes, this Expert-level Aethos model delivers flawless performance across long endurance rides, spirited climbs, and technical descents.

The Aethos Expert features Roval C38 Disc carbon wheels for optimised stiffness, reduced rotational weight, and smooth acceleration, paired with a featherweight carbon frame engineered for ultimate stiffness-to-weight balance. Specialized’s revolutionary carbon layup and frame geometry subtly reshape traditional road designs to maximise power transfer, stability, and comfort, creating a bike that climbs efficiently, handles responsively, and rides beautifully all day.

Every detail, from precision derailleur hangers to the Roval Alpinist carbon seatpost, is engineered to minimise weight while enhancing ride characteristics. With a frame optimised for both mechanical and electronic drivetrains, hydraulic disc braking, and long-distance comfort, the Aethos Expert Rival eTap AXS is the ideal high-performance road bike for climbing, endurance, and all-around riding excellence.
