2021 Specialized Aethos Expert Carbon Di2 Disc Road Bike in Blue

Season:2021

Brand:Specialized

Code:299409328850

What if Specialized used every ounce of experience they`ve gained serving riders over the past 46 years and built a bike made simply for the love of riding?.

The Aethos is designed to straddle the line between perfect ride quality, extreme lightweight, and undeniable style. The Aethos Expert model is no exception. With quick-shifting, low-maintenance Ultegra Di2 electronic shifting and hydraulic disc brakes paired with bomb-proof DT Swiss R470 Disc wheels, you have the perfect steed to excite you out on the road.

Key Features:
  • Aethos FACT 10r Carbon Frameset
  • Shimano Ultegra Di2 Disc R8070 Groupset
  • Roval Alpinist Carbon Seatpost
  • Threaded Bottom Bracket
  • Tyre Clearance for up to 700x32mm

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, subtly altering 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 has been 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 Specialized 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. They 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
