Wanting some opinions from aethos owners. I currently own a Tarmac SL6 and am looking at buying an aethos expert to use as a race bike. Has anyone here thrown on some deep section wheels and raced an aethos? Race experiences, results, and just some general advice/opinions? Thanks

The geometry is basically the same as a SL6. You will probably not be able to notice a difference between the two bikes. [image] Geometry Geeks The world's biggest open geometry database. Find bikes by name or numbers. Easily compare bike geometry side-by-side. …

No it’s not allowed - Specialized heavies will come to your house and smash it with hammers if they find out. JK, if it’s good enough for Kasper Asgreen , it’s good enough for you :+1:

This is a bit of a silly question. It’ll be highly capable. You might give up 10w in the lab, but only 2w-5w aero watts in the real world (water bottles and wind turbulence, etc). All the BS around the bike is because Spec had to justify it’s existence after going all aero. The Aethos is only light…

Didnt’ see that… thanks - guess I’m wrong about the mfg process and safety factor. They re-weighted their tube sizes to be downtube and headtube fat (less aero), while demphasizing the BB size, with the secret being the tapering from the big tubes to the smaller ones. In any case, the rest of re…

Is there a reason you don’t want to use the Tarmac as a race bike?

No real reason. Just looking at different race bike options for next year

I’d keep the SL6. The big benefit of the Aethos is its low weight, the more expensive model I think clocks in at 6 kg. But if you want to race, that is all null and void, because you need to stick to the 6.8 kg weight limit. Even if the Aethos is lighter than your SL6, I don’t think it is worth it. …

Unless you are racing at the highest levels the weight limit doesn’t matter… no one is weighing bikes.

I have never raced in the US, but here in Japan they do check bike weights (and gearing for juniors) in all JCBF sanctioned events. In the non-sanctioned events I have participated in, they haven’t. In the UK hill climb scene, they also don’t seem to adhere to the 6.8 kg weight limit either.
