S-Works Aethos - Shimano Dura-Ace Di2

The Aethos is designed for riders who love the pure experience of cycling. While it delivers nothing short of performance, it achieves this with the world's lightest frame and uncompromising style. Billions of calculations went into creating one thing: the perfect ride. The Aethos frame combines ultimate ride feel, light weight, and style through a reinvented road 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 results in the lightest frame available at just 585 grams in size 56cm. The frame excels whether you're accelerating up steep pitches, descending technical descents, or enjoying all-day comfort on long coffee rides. The bike features a perfectly balanced combination of front and rear stiffness with exceptional ride quality. By studying how carbon fiber flexes and breathes, Specialized discovered groundbreaking insights about how forces flow through frames, creating a ride that sets a new standard. 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, this is a top-tier ride that gives up nothing in the name of performance.
