6kg!! Specialized S-Works Aethos Review - Is lighter really better?

I've ridden the brand new Specialized S-Works Aethos 6kg superbike for the first time! Yeah, it's pretty awesome...
The bike I've ridden costs £10,750 with Dura-Ace Di2 and Roval Alpinist carbon wheels. The 6kg weight is for the size 56cm I rode.

I own this bike so here are my thoughts. Hopefully it might help somebody since most of us have to make these large financial commitments without having much of a chance to test ride these things. My setup is the S works Aethos with SRAM red, ENVE 4.5 AR wheels, ENVE cockpit, 28 tires. It’s a great bike. The first thing you have to do is learn to trust it. When you first pick it up it’s so light you worry that it might snap in half. Once on the bike that concern quickly fades. Surprisingly it isn’t the climbs that made it stand out as much as descending and cornering. It feels planted and agile at the same time. I would often read in bike reviews about a particular biking making you want to push harder and go faster and riding this bike is the first time I really “got” that idea. It does seem to do that. I’m not sure I understand why but I think it’s because you feel such an exhilarating response when you pedal hard. It responds and accelerates so well that you want to feel that feeling over and over again that you get when you put in the effort. You really feel like it rewards you for it. I assume it’s the light weight. It doesn’t maintain as speed as efficiently as my aero bike when I’m on a flat and not pedaling but it does seem significantly more responsive on the flats to even light effort. The GRAN FONDO cycling review made a comment similar to this and I would have to say I agree 100%. (In fact their whole review is spot on in my opinion and is 10x better than mine so you might want to check it out on their web site) I don’t notice as much of a pronounced benefit when climbing as I thought I might with such a light weight bike but it climbs great nevertheless. The miles I have on it so far have not involved much climbing though so I will hold judgment on that for now. It definitely feels like a race bike geometry and apparently it is the same geometry as the SL7. Given the fact that Specialized is not marketing and didn’t focus their design on this as a race bike I would have thought that a more relaxed geometry would have made more sense. I probably would have preferred that frankly. It is still a very comfortable bike however. Like every bike out there it’s not the right bike for everybody but I do think it’s the right bike for me as I don’t race, typically do lots of climbing on my long rides, and given my relatively limited skill level probably notice the benefits of a light weight bike over a heavier aero one. Yes it is ridiculously expensive but keep some things in mind. A lot of what you’re paying for is the years of R & D that Specialized put into developing the technology for this bike. That was years of financial investment with no return. In my experience, regardless of the product, we all think an “outrageous” price on anything is always one level above whatever it is we can afford. I’m certainly guilty of this. If you’re reading this thread your bike, although perhaps much less expensive than this one, is almost certainly ridiculously expensive and forever out of reach to somebody. so perspective is important. Less expensive bikes and people who love to ride but have less financial resources will almost certainly benefit in years to come from what Specialized has done and learned here. We can all be grateful for that.

[@davidarthur]

Great insight, thanks for sharing with us. Interesting comments about how responsive it feels on the flat and stable on the descents, mirrors my findings but only based on one ride

[@paulrichards6521]

@@davidarthur Thanks for the review. I'd be interested in your thoughts on this vs. a high-end round tubed climbing bikes from a couple of years ago. I have 2016 SuperSix HiMod (an all time classic). With a bit of weight management, I can get that to 6.5kg. I know this a disc brake bike at under 6kg which is very impressive, but I'm curious about your thoughts on ride feel - do you think that it would be noticeably better? Difficult question with so little time on the bike I know, but any thoughts appreciated.

[@markp353]

Had a quick look at the geometry of a 52 Aethos compared to my SL6 Tarmac Comp. Stack and Reach are identical. Wheelbase 5mm longer on Aethos. Quick glance, apart from weight not a whole lot differrent except the price. LE model is $22K AUD - unbelievable. It seems the "just for the love of riding" is only for the rich. Unless I buy 2nd hand in the future I will not be buying another Specialized as their range of bikes are just pricing themselves out of consideration. Even entry level SL7 is about $7,500AUD

By the way, I think they're all crazily priced :-) just that using the Huru as a baseline actually makes the Aethos price right in a relative sense.

So they made a new climbing bike...the "one bike to rule them all" mantra just went down the drain...how is this compared to a TCR Advanced?

[@waynedoherty7758]

www.velonews.com/gear/road-gear/road-bike-of-the-year-giant-tcr-advanced-sl-0/ Velo news says the TCR was the only new bike to approach the Aethos in terms of ride quality. But it's more affordable, and a little bit more aero. Given in cycling reviews 'everything is awesome' to avoid upsetting bike brands, there seems to be genuine love and enthusiasm for both the TCR and the Aethos! One again great content from David!

Di2 only?

[@johnc3605]

Does it come with pedals or do you have to shell out for a set before you even ride it? They claim they're saving the environment by NOT including the pedals with it I bet. This was my experience with my new 2021Diverge Pro Carbon. You can write in to request a set they say. Cheap *******s. Beware of light weight rims that are not balanced. I experienced a 'death wobble' at high speed on my bike. It took a couple of washings to clean those shorts. I balanced them myself with four good size pieces of split rubber vacuum air hose. Per wheel!! Without this balancing (due to the weight of the valve stem) my rims hopped up and down forcibly when revved up on my stand. Hell, even my old DaVinci twirled around smooth as silk. And, light weight in a wind is another matter too. Hang on tight. I still hope for a call from the Specialized rep wrt these unbalanced Roval rims. Buyer beware is my new motto. Test ride this bike yourself before purchase. I saved all my life for my one extravagance. ...didn't come with pedals. lol.

2013 Super Six Evo 58cm 6.3 Kg with pedals.

[@edwardhodgson3122]

And not a disc brake or associated hydraulic hosing in sight...

[@davidarthur]

This has disc brakes, electronic gears and a power meter and normal clincher tyres so pretty impressive I reckon, so you’re getting more performance/capability

[@ThePaulKat]

@@davidarthur Sorry that’s not correct is it? Electronic gears, disc and power meters don’t add performance/capability to a cycle , improves the experience possibly. A power meter only adds minimal 50g if you go for pedals. To an experienced cyclist the benefits of disc do not outweigh the drawbacks. Look at the pro’s who have a choice and aren’t incentivised to ride disc. TDF? This year I have predominantly alternated between my C60 rim & C64 Disc while I love the hydraulic actuation of disc (Campagnolo SR eps & Carbon Ti rotors) the added susceptibility to crosswinds is notable as is the brake fade when coming to a dead stop at the bottom of Buttertubs after descending at 55/60mph. At high speeds my Zipp NSW rim brakes provide greater initial bite which I prefer and do not suffer the fade on Buttertubs.

[@TimPat]

I wonder if Specialized will offer a 1x build as well

[@davidarthur]

That would be cool. The front mech hanger can be removed. Campagnolo Ekar maybe?

[@TimPat]

@@davidarthur Absolutely. BTW do continue covering these super bikes. It makes for quality content! Even though pricing is astronomical.

Specialized: Let's make a simple frame with a next to nothing paint job, make sure its is just a bit lighter whatever is out there and sell it to the sucker for twice the price.... Kaching!!! $$$

Weight weenies have to get rid of their super six evo's and get this

[@mateuszkosek2652]

Yeaaah sure... Weights exactly the same but you have to spend 10k and get use to hearing ding ding ding (discs rubbing) :D 8 years difference and still worse.

[@mateuszkosek2652]

Personally i think it's not gonna be any noticably stiffer than Cannondale super six evo, ss evo frame was around 700g, this one is 600g, while stifness/weight might be better on Spec, when you add weight into equation they are probably identical in bending stifness. So we traveled in time 8 years from the first supersix evo and there is almost no progress in superlight bikes, adding discs doesnt make anything better except profits for those companies, great job Specialized. Btw just look at the Pogacar and Roglic bikes at TdF! great job Specialized ;)

[@oreocarlton3343]

Discs. Weight.

[@mattkrivosudsky9057]

Looks like an Open Min.d, same concept - create a bike for the love of riding.

[@dannyMCDelight]

$12,000 bikes should be lightweight, fast, and perfect

[@elevenc8131]

And custom....

[@rlsedition]

When you spec an S-Works model, be prepared to pay for it. There are now two lower priced models of this Aethos available.

[@MSimky]

@@rlsedition What do you give up when you drop down from S-works?

[@sweatnosweat]

10.000 13.000uss and cables? nexttt

[@JasonHughesUK]

How much does it weigh David? 😉

[@jev2867]

Weight as little as 10k broken down $50 bills.

[@GS-pk9rd]

Definitely more than 6kg!

[@steppings5645]

A move to the darkside, but at £4000 for the frameset I'm afraid i'm out.

[@faisalalsaiful3838]

i actually really liked the bike....... ..if they could make it 7 grand cheaper🐸

[@mattball420]

Exactly. Aero bikes are more expensive because they use more carbon on the wider frame but this one uses even less layers than normal.

[@rlsedition]

They have. The Expert model is $5200.

[@MSimky]

@@rlsedition They need to put some rim brakes and mechanical shifting on as an option to reduce costs and weight.

[@KenChiwo]

Rather get the Canyon EVO...which weight the same or less, but cost $4K less!

[@rlsedition]

No, Canyon doesn't offer a frame at 588 g.

[@drtyjrze]

So many comments about the price...clearly it’s not marketed to you. Stop hating on how other people decide to spend their money and move on with your life.
