First road bike - "relaxed" vs. "aggressive?"

[Eden]

Maybe somebody can double check my math on this: I just compared the Ruby and Amira base models in a size 48 and size 51. The ONLY differences in geometry between the two bikes is that the Ruby has a longer stem (which would arguably make it less, not more relaxed, but in any event is easily changed) and the Amira has a shorter seat tube by 10mm.

?? I'm at the low end of things. I can't comfortably ride a 48 in any model - top tubes are just too long. Comparing the 44 Amira to the 44 Ruby they are substantially different. The Ruby has a shorter seat tube, shorter top tube, longer chain stay, different seat/head tube angles and fork trail, longer wheel base and longer head tube. That certainly sounds like it makes it a more relaxed, more upright bike. The 48 in the Ruby is not the same as the 44 in the Amira either.

My Ruby was the original Ruby - somewhere in between a Roubaix and an S-Works on the aggressive/relaxed scale, when I bought it. I understand they've gone more towards the Roubaix since bringing out the Amira. It had the shortest top tube on the market - good for my short arms, not to mention it was, I think the only carbon bike that came small enough for me at the time. I was a bit concerned that the Amira would feel too long, but the cockpit actually feels a bit shorter to me and it is actually more comfortable for my neck and shoulders than any bike I've had thus far.
