Today, Specialized unveiled Specialized Aethos, a non-racing road bike.
Breaking UCI rules, Specialized produces the lightest road bike, Aethos (pronounced as Ay-thoss) with the lightest disc frame, which weighs just 585 grams.
Fast fact: The Union Cycliste Internationale is the world governing body for road racing and the UCI’s weight limit of 6.8kg has been strictly in place since 1999. This has meant race bikes, especially those from the last decade with advanced carbon construction, have been inherently compromised in performance.
At just 5.9 kilograms, the insanely light Specialized Aethos complete bike is the start of a new breed, a bike engineered to create the perfect ride, one that breaks all the rules. This is a machine not built for racing but for the best and purest ride experience possible, every time you roll out.
The engineering lead on the Aethos was Peter Denk, the man behind legendary bikes including the original Scott Addict and the first two generations of the Cannondale SuperSix EVO.
The S-Works Aethos frame is compatible only with electronic drivetrains and hydraulic disc brakes. The complete bike comes specced with 700x26mm tyres but you can fit tyres up to 32mm wide on 21mm rims. This leaves 4mm of space all round.
The Aethos uses a 68mm BSA threaded bottom bracket, like the recently released Tarmac SL7, and takes a 27.2mm diameter seatpost.
The 1248-gram Alpinist wheels and new Alpinist bar/stem combo were tailormade for Aethos and the ride of your life.
Specialized eliminates traditional stiffness layers, reducing the plies necessary to build the bike by 11% compared to a Tarmac SL6. With a size 56 S-Works level layup with Satin Carbon/Jet Fuel finish, it has the same geometry as Tarmac SL7.
