S-Works Aethos - Shimano Dura-Ace Di2

The Aethos is designed for riders who love the pure experience of cycling. While it delivers nothing less than top-tier performance, it achieves this without compromise to style or ride quality. The frame represents billions of calculations in pursuit of one goal: the perfect ride. The Aethos frame is the world's lightest, weighing just 585 grams in size 56cm (S-Works). It combines ultimate ride feel, light weight, and refined aesthetics through a reinvented road frame shape that delivers massive gains in stiffness and balance without affecting weight or durability. An entirely new layup and manufacturing process perfected over multiple decades makes this possible. The frame achieves its exceptional ride characteristics through a perfect balance of front and rear stiffness combined with outstanding ride quality. By studying how carbon fiber flexes and how forces flow through frames, Specialized discovered groundbreaking insights that set a new standard for ride feel. Every detail has been designed with style, weight, and durability in mind, from derailleur hangers to the fork expander plug. The bike is spec'd with Roval's all-new Alpinist carbon seatpost and wheels, further reducing weight and improving ride characteristics. Paired with Shimano's legendary Dura-Ace Di2 groupset and Roval's featherweight Alpinist wheels, the Aethos delivers a perfectly balanced top-tier ride that gives up nothing in the name of performance.
