Comparing both the Aspero and the Aethos, using the same wheelset at first running 35mm Gravelking slicks I was taken back on how comfortable the Aethos is. I didnt realize how stiff "feeling" the Aspero is/ was for me.. I then picked up some supple 28mm tires for the Aethos to further my experimentation and couldn't believe how comfy this combo is.. But I digress, just setting the stage.
The topic at hand, why would you get a Roubaix, when the Aethos is so comfy and has racier geometry compared to the more relaxed Roubaix.
My back of the napkin comparison doesnt balance out between these two bikes.
Aethos: Has more tire clearance (I tested 35mm and 36mm with good clearance), is very compliant and has Specialized Tarmac Geometry, can be built lite without fancy parts.
Roubaix: Limited to 32-33mm tires, Relaxed geo, yes its more Aero in some areas, but the cockpit is probably less aero than the Aethos.
I understand the Roubaix was designed for Paris Roubaix, but it seems a bit dated now.. If I was a pro, and I am not, I think I would opt for an Aethos for Paris Roubaix. Probably build it with triple wrap bar tape and 32mm hell of the north tires.. Aero wouldnt be a concern as the Peloton would surely provide enough coverage from the wind, and the bike is damn comfy and lite.
I say all this with much appreciation for the Roubaix, I actually considered it instead of the Aethos, but it just seemed more of a compromise. I liked that I could run 35/36mm tires and still have a comfy and slightly aggressive geo bike for certain occasions.
I would think the Roubaix will get redesigned for 2022/23 with more tire clearance, tweaked geo to reduce the stack height a bit and possibly a bit lighter.
Anyway, anyone else feel the same way about my ramblings
