Specialized Aethos Sport 2025 - Road Bike

The Aethos Sport is all about delivering the perfect road ride whether you're climbing steep switchbacks, descending winding mountain passes, or simply racking up miles with your local club. With a frame weighing just 585g in its premium form, Specialized has taken the learnings from decades of carbon development to create a lightweight yet durable FACT 9R carbon frame with exceptional stiffness and balance.
Key Features:
- FACT 9R carbon frame with Rider-First Engineered™ design and classic road geometry
- FACT carbon fork with 12x100mm thru-axle and flat-mount disc brake mount
- Shimano 105 mechanical 12-speed drivetrain with Hollowtech 2 chainset
- Shimano 105 hydraulic disc brakes for consistent, reliable stopping
- DT Swiss R470 Disc wheels with Turbo Pro 700x28 tyres
- Roval Alpinist carbon seatpost for reduced weight and added comfort
- Available with 0% APR finance
The Rider-First Engineered™ geometry ensures consistent handling and performance across every frame size, while subtle updates to classic tube shapes boost ride quality without compromising style or weight. This means the Aethos Sport doesn't just climb and descend well, it feels intuitive and engaging, mile after mile.
The Shimano 105 mechanical 12-speed groupset provides crisp, reliable shifting and a wide gear range for tackling varied terrain. Combined with Shimano’s hydraulic disc brakes, you get powerful, modulated braking for confidence in all weather conditions. The FC-R7100 chainset and 11–34T cassette offer the gearing you need to stay smooth on the flats and spin efficiently up the hills.
Rolling on DT Swiss R470 Disc wheels, the Aethos is fitted with Specialized Turbo Pro 700x28mm tyres, delivering fast, grippy performance across your favourite roads. The Roval Alpinist carbon seatpost helps smooth out the ride while cutting weight, and the Body Geometry Power Sport saddle keeps things comfortable over longer efforts.
Clean internal cable routing, a threaded bottom bracket for long-term serviceability, and sleek aesthetic details complete the package. At just 7.76kg, this is a lightweight road machine that’s ready for serious performance without sacrificing everyday practicality.
