An entirely new model from Specialized is quite the treat, and is especially surprising given the impressive all-round abilities of their latest Tarmac. You could be forgiven for wondering what gaps were left to fill - but Specialized have been on a creative roll of late, and their new model reflects that desire to shake things up.

The new Aethos is what happens when the designers are set free with a completely clean sheet of paper to design a real "rider's bike". What does that mean? Well, it's incredibly lightweight, but that's almost a side-effect rather than the primary goal. Their aim is to create a bike that takes all the expertise and tech that benefits Pro race bikes, and to build it into "a bike built simply for the love of riding". So, handling and ride quality are paramount, and every aspect of the frame was reconsidered from scratch (and as part of the complete whole).

Roval's recently launched Alpinist wheelset, together with the Alpinist Bar/Stem combo, have hinted at a new level of lightweight componentry, and the Aethos makes the perfect platform for these (and also features a new Alpinist carbon seatpost - although the classic 27.2mm size means that you have many options open for custom builds).

Break The Rules

The creation of our Aethos road bike started with a question:

"What if?"

What if we built a bike focused around the purest imaginable road riding experience? What if we built a bike to maximize the timeless moments where everything disappears and human and machine become one.

We all know these moments, the ones where we lose ourselves in the reverence of dancing up a climb or telepathically carving through a turn, where we feel liberated from the constraints that surround everyday life and the miles just melt into hours.

The Aethos wears its high-tech design well. The overall shape of the frame is remarkably traditional at a glance, but beneath the surface Specialized have worked wonders with their carbon layup to reduce the number of stiffness layers required, without compromising on the actual stiffness. In fact it has been tested as significantly stiffer, and yet lighter, than the previous benchmark Cervélo RCA.

Those understated aesthetics are matched with unusually subtle logos and some of Specialized's typically gorgeous paint schemes.

Cutting-edge Design

The S-Works Aethos uses Specialized's stiffest, lightest FACT-12r carbon to achieve a painted frame weight of 585g in the lightest colourways.

A complete S-Works Di2 build weighs in at just 6kg in the Carbon/Chameleon Red Gold colourway.

The S-Works frames are flat mount hydraulic disc-brake only (no surprise there) and are also only intended for use with electronic groupsets.

The front derailleur hanger is removeable, and a cover is included to keep things neat and tidy for a seamless look.

The stock builds come with 26mm tyres, but there's ample clearance for up to 32mm (on 21mm rims, giving 4mm of clearance all round), as you'd expect for a modern performance bike.

Classic Details

With a threaded bottom bracket, 27.2mm seatpost and fit/handling identical to the perfectly poised and race-tested Tarmac SL7 the Aethos features a raft of welcome standards where required.

It's UCI approved, too, despite the potential to build it well below their weight limit, so you'll be safe to take it racing, whether pro or amateur.

Weights

Specialized know that on a bike like this we want to have some proper detail on the frame weights, and so they've broken it down by colour and by size.

The lightest colourway is the Satin Carbon/Jetfuel at just 585g. Other colour options add roughly 25g to the total (e.g. Satin Carbon/Chameleon Red Gold or Satin Carbon/Gloss Black Chrome) with the most lustrous (e.g. Gloss Clay/Flake Silver or Satin Flake Silver/Chameleon Red Gold) adding around 45g more.

The average production weight in their Satin Carbon/Jetfuel colourway is quoted as:

49cm - 550g / 52cm - 565g / 54cm - 575g / 56cm - 585g / 58cm - 623g / 61cm - 643g

S-Works Aethos

There are two S-Work complete builds available at launch, featuring either Di2 or eTap shifting. Both are priced at £10,750. It's also available as S-Works frame only, in a host of typically stunning paint options, at £4000 (including the new Roval Alpinist seatpost).
