Specialized S-Works Aethos Disc Road Frameset 77221-0252

Specialized S-Works Aethos Disc Road Frameset Build up your dream bike with this featherweight Specialized S-Works Aethos Disc Road Frameset. The FACT 12r carbon, with a completely new layup and altered tube shapes, allowed huge amounts of weight to be shaved off during the design phase and the resulting frame alone sits at a mere 588 grams in a size 56. The quest for a 'perfect ride' was achieved here, following years of extensive development and the Aethos takes road bike performance in a new direction. Beautiful to ride, it's a bike for everyone and combines the insanely low weight with strength, stiffness and responsiveness, using the same fit and geometry as the Tarmac SL7. The frameset is designed to be compatible with electronic disc groupsets only and has the clearance for wider 32mm tyres. A Roval Alpinist carbon seatpost is supplied and it's the brand's lightest to date, completely in keeping with whatever build you decide on.
