The 2023 Specialized Aethos Pro Shimano Ultegra Di2 Road Bike promises three things; exceptional light weight, perfectly-balanced ride characteristics, and undeniable style.
The Aethos is the result of billions of calculations in the pursuit of one thing; the perfect ride. 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. By reinventing the traditional road shape found on bikes of the past, Specialized have subtly altered these shapes to deliver massive gains in stiffness and balance, all without affecting weight or durability.
The Aethos Pro comes with Shimano's Ultegra Di2 that delivers clean, crisp shifts and Roval’s Alpinist wheels mated to DT Swiss 350 hubs for a no-fuss build that delivers, mile after mile.
This bike is perfect for
Road riders who want a classic lightweight bike with the latest electronic gearing.
Key Features
- 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 fibre, we were able to discover ground-breaking 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
If you are buying a road bike one of the big differences between models will be which gears they use. Most manufacturers will make the same bike, using the same frame but putting different gears and wheels on it. So for instance you can buy a Trek Domane AL 2 Disc with Shimano Claris gearing for £975 or get the Trek Domane AL 4 Disc with Tiagra gearing for £1625. They are fundamentally the same bike. One comes with the Shimano Tiagra gears and the other comes with Shimano Claris gears.
In most cases, the bottom of the range gears and top of the range gears will basically work in the same way. The big differences are in the quality of material used and the weight. Top of the range gears will be lighter and smoother to use.
One thing to watch out for when comparing bikes is whether the full groupset is being used. If you are buying a bike that has Shimano 105 gears on it. Shimano makes 105 brakes, gear levers, front and rear derailleurs, cranks, chainrings and bottom brackets. So basically all of the running gear on the bike. Some bike manufacturers will fit the full groupset, others will fit Shimano 105 front and rear derailleurs but use their own brakes and cranks to save a few pounds. So if you are comparing bikes be sure to check how much of the groupset the bike actually uses.

Road Bike Buying Guide
Nothing beats the feeling of effortless speed you get on a road bike. There are lots of reasons to ride a road bike, from the simple joy of it, to racing, long distance challenges, or café rides with friends. Whatever you want to do there will be road bike out there for you.
Men’s and Women’s road bikes
Nearly all manufacturers have stopped making dedicated men’s and women’s bikes. They are now all unisex. What you will see is that on smaller bikes, brands will often fit a wider saddle (generally more female friendly). On larger bikes they will often fit a narrower one (generally more male friendly).
Disc or rim brakes
It is getting increasingly hard to buy new bikes with rim brakes as the industry has almost exclusively switched to discs. The reasons for this are pretty simple. Disc brakes are much, much, more powerful than old rim brake systems so you can stop a lot more easily and safely. Disc brakes also allow much bigger tyres to be fitted which is more comfortable. Older disc brake systems did often suffer from rubbing and squeaking. While this hasn’t been completely fixed yet it is much less common on modern bikes with hydraulic brakes. Mechanical disc brakes can still take a bit of fettling to get them right so go for hydraulic if you can.

Who are Specialized?
Specialized is one of the best-known quality bike brands in the world. Started by a group of riders in 1974. A fact which has guided their decision making ever since.
" Made for riders, by riders."
They strove to make the best quality tires when quality tyres weren't around. When people wanted to ride cruisers in the dirt, they made the first production mountain bike. When roadies wanted to go faster, Specialized doubled down on carbon and built their own wind tunnel.
Bikes like the Allez, Rockhopper and Stumpjumper have developed followings and reputations of their own. Specialized has a reputation for making high-end, high-quality bikes. Specialized bikes always look great with high-quality paint and sensible sizing hel0s you get the right bike each time. If you buy a Specialized bike you can be guaranteed it will do what it is supposed to and will last.
