Cannondale SuperSix Evo kids bike

I did read it all but couldn't really understand what you are trying to do. If I was you I'd go custom steel and do a WW build; it won't be as light as carbon but it will fit well which stands by: Fitness > Fit > Aerodynamics > Weight

and it won't look rank. 90mm stem; saddle position and that amount of spacers mean you are practically a MAMIL

also I am 170.5cm myself and I know your pain and scared of scheritt outcome of my fit :p

on top of my head I can only remember 3 current pros at similar height (quintana, Rodriguez and paolini) conincidently they all ride Canyon of similar sizes I think. Have you considered that?

The easiest way to boil down what I'm doing: The contact points are perfect, lets aim for performance advantages. I'm not going to sacrifice performance just so I can pander to the fashion for stem slams.

I know the bike is rank as is, but hopefully a repaint and some different components and it'll look a little better, however, even if it looks like a MAMIL's bike, I would hope that I don't look like a MAMIL, and I'm certainly a little bit faster than MAMIL pace...

Interesting point to the Canyon. Unfortunately even the XS Aeroad frame has a 528mm top tube. However, Quintana's old Pinarello was a 44cm, with a 508mm top tube, so that would work for me. Unfortunately, smaller frames mean shorter headtubes and I'm just going to end up with more and more spacers. I think this Cannondale is a decent intermediary fit until I can afford a custom Parlee.

You'll love getting fitted by Scherrit, trust. Even if you've got to sell everything and embrace the spacer, the improvement in ride quality will overrule it all.
