Go ride it. The data is quite useless and only way to tell is the good old 'butt o meeter'. If anything the ride feel is closer to sl7 than sl6.
Both are very well connected once you remove the placebo effect of “this new bike is amazing”. Claiming the opposite is either being totally insensitive (and many of us or even journalist are) or trying to justify our purchase.
Btw: I will test b2b the sl7 and aethos next weekend.

Question for the mechanics out there.

On the new threaded bb of the Aethos, will a sram dquarq bb30 crankset work? If there is need for an adaptor, does anyone know which one? Thanks!!

Not a mechanic, measure your spindle and must be the long bb30 one(100mm) and you'll need a bsa30 bb english.

I think the point for the emphasis on stiffness on this particular bike is because it's a super WW frame, which is often known for lacking in stiffness both vertical and torsional.
Are they though? Where's the data showing this, especially for recent WW frames? I know aero frames have less compliance than round tube frames, but that's separate from torsional rigidity.

It's hardly any use to ask a guy who bought a bike how it rides. Have you ever heard one say, oh, it sucks because bla bla bla.
People IMO, often experience what they're told to. Only way for you to have something to grasp on is stiffness data. The rest is what you are told and it can be BS and wishful thoughts. Only time i heard someone say one negative of a bike, is when they've bought a new bike. I have never heard anyone say, oh crap, this new bike is not as good as my last bike.
How can you have a grasp on stiffness data if you don't know how it was generated, whether data you get for one bike can be compared to that of another, or what the real world implications of the data are? Not to mention stiffness data doesn't seem easy to come by... the most recent comparison I could come across was done back in 2009:

You're right that people's reviews have their own biases and problems, but stiffness data does too... especially if it's part of a manufacturer's marketing strategy. And I disagree that people don't say negative things about their bikes.... if anything they exaggerate them. But at least reviews provide multiple data points you can interpret on your own. Stiffness "data" might be useful or complete shit. And even if it's useful odds are you don't know how that data correlates to the real world anyway.

Great stuff, Ome. Will be interesting how you compare your sl7 to this one

Usually size 49 specialized bikes look *ok*. Aethos is a massive exception.

it's tough to make small (and very large) frames to look good. BMC TM01Road size 47 looks great, but it's pretty much everyone elses 50/51 anyways.

No expert frame in the UK, that sucks, was half hoping for that.

I have a test ride of the Aethos Pro with Sram Force scheduled for Saturday. I'm going to decide between the Tarmac SL7 Pro which I have test ridden with Ultegra di2, and the Aethos Pro. If I go with the Tarmac I'll buy the frame and build it with Sram Force staples and CLX 50 Wheelset, I want a tubeless Wheelset. Not sure what I'll do about Wheelset on the Aethos if I like it better. Decisions, Decisions. Any suggestions for a tubeless Wheelset? The Aethos comes with a 33mm deep wheel.
Thanks!
