At the core of its performance is the Shimano 105 Di2 12-speed electronic drivetrain offering the smooth, precise shifts of Di2 in a more accessible package. With a wide-range 11-34t cassette and FC-R7100 chainset, the Aethos Comp has the gearing to tackle everything from punchy gradients to fast-paced group rides. Shimano’s R7170 hydraulic disc brakes offer confident stopping in all weather conditions, perfect for riders who want consistent braking through descents and tight corners.

Rolling on DT Swiss R470 Disc wheels, the Aethos maintains its light and fast character, paired with Specialized Turbo Pro 700x28mm tyres for the ideal mix of grip and speed on smooth tarmac. Comfort and control are further enhanced by the Roval Alpinist carbon seatpost and Body Geometry Power Sport saddle, designed to support longer rides with efficient power transfer and fit-focused support.

The Aethos also stays true to clean aesthetics, with internal cable routing, subtle branding, and thoughtful details like a threaded bottom bracket for long-term serviceability. Weighing in around 7.5kg, it’s incredibly light for a disc brake-equipped bike proving that comfort, simplicity, and race-ready performance can coexist in perfect harmony.
