Specialized announces 'cheaper' Aethos Pro and Expert models

When Specialized launched the S-Works Aethos two weeks ago it threw a curveball at the cycling industry. An alternative approach to the bike design ethos and some seriously impressive performance figures in weight and stiffness makes it one of the best road bikes available. The S-Works Aethos frameset is beautifully crafted and ultra-refined, with a ride quality that continues to capture the hearts of all those that ride it. However, for consumers who wanted to buy one for themselves, the price tag is, unfortunately, an equally impressive figure.

The Expert and Pro models are built around the same Aethos frame designs, but made from Specialized's Fact 10R carbon and layup rather than the S-Works Fact 12R material. As the Aethos' design is primarily based on the optimisation of tube shapes, Specialized claims the ride quality and handling is unaffected by using the Fact 10R carbon. The Fact 10R frames weigh in at a still-very-respectable claimed 699g (Satin Carbon/Flake Silver colourway), just 114g heavier than the S-Works model. Other than the material and mechanical cable routing compatibility, the Fact 10R frames share the same geometry and features. This means you get the same sharp handling of the S-Works Aethos and Tarmac SL7 as well as neat touches such as a BSA threaded bottom bracket, standard seat clamp and removable front derailleur mount.

The Aethos Pro comes in two build options that cater to both Shimano or SRAM preferences. Both are equipped with Roval's lightweight Alpinist CL wheels and S-Works Turbo tyres. Both models come equipped with a power meter as standard although the SRAM Force eTAP Pro will retail for £7,500 - £250 more than the Ultegra Di2 model. In terms of weight, the Ultegra-equipped model tips the scales at 6.58kg and the SRAM version comes in a little heavier at 6.82kg.

While it's hard to describe a bike that costs £5,500 as a 'budget' option, the Aethos Expert is almost half the price of the S-Works version. It's also £1,750 cheaper than the equivalent Pro model yet features the same Fact 10r Aethos frameset. The Aethos Expert is powered by Shimano's Ultegra Di2 groupset but saves money over the Pro model by substituting in an alloy handlebar, DT-Swiss R470 wheelset, and the Power Expert saddle. Weight is still impressive with the Aethos Expert coming in at 7.14kg according to Specialized's figures.
