2025 Specialized S-Works Aethos SRAM RED AXS in Satin Doppio

Season:2025

Brand:Specialized

Code:5432894353987

Don’t get us wrong, we’re all for racing. Grand Tour top steps, Classic’s Monuments—they’re in our DNA. But sometimes riding simply to ride, riding for the love of riding, is just what we need. And this is what the Aethos lives for. Sure, it’s given nothing up to performance, and happens to be the lightest frame out there, but with no compromise to style. Aethos: Billions of calculations in the pursuit of one thing—the perfect ride.

Top off the world’s lightest frame with a full SRAM RED AXS groupset with power meter - the lightest electronic groupset ever - and Roval’s featherweight Alpinist CLX II wheels and you’re left with a perfectly balanced top-tier ride that gives up nothing in the name of performance.

Key Features:

  • The Aethos frame has been designed with the perfect combination of ultimate ride feel, light weight, and style—from accelerating up steep pitches and descending technical descents, to all-day saddle comfort on even the longest coffee rides, the Aethos hits the mark. But how, you ask? By reinventing the traditional road shape found on bikes of the past, we’ve subtly altered these shapes to deliver massive gains in stiffness and balance, all without affecting weight or durability. Pair that with an entirely new layup and process that we’ve perfected over multiple decades and you have the lightest frame out there (585 grams, S-Works, size 56cm). The Aethos is more than just a new bike, it’s the first of a new breed.
  • A featherweight frame is useless without confidence-inspiring ride characteristics, which is why we’ve developed the Aethos to have the perfect balance of front and rear stiffness combined with exceptional ride quality. By studying the flexing and breathing of carbon fiber, we were able to discover groundbreaking findings about how forces flow through frames. Just a few pedal strokes and you’ll realize this sublime ride sets a new standard.
  • Every detail, from the derailleur hangers to the fork expander plug have been designed with style, weight, and durability in mind. We’ve also spec’d it with Roval’s all-new Alpinist carbon seatpost and wheels, further saving weight and improving ride characteristics. Everything in pursuit for the perfect ride.

Click & Collect Orders

Please be aware Click & Collect orders may take some time to fulfil. We advise not to travel to your chosen store until you have been notified that your order is ready for collection.

Spread the cost of your new bike, helmet, safety equipment and accessories paying via instalments being taken directly from your wage. The payments for the Cycle To Work scheme are taken out of your gross wage and your Tax & NI contributions are then worked out based on your new lower gross wage which is how you save money on your new bike and equipment.

At the end of the time period specified with your Cycle To Work scheme you then have the option of buying your bike or to continuing to use it while you work for the company. If you decide to purchase the bike, the balance you owe will be based on a percentage of how much the bike was worth at the time you took out the Cycle To Work scheme.

We know how eager you'll be to jump on your new bike and hit the dirt or tarmac, so we give you everything you need to get you set up quickly. For full instructions on how you're bike will arrive and what you'll need to do, visit our How Our Bikes Are Built page
