Rapha, nice but a bit pricey?

It says something a bit more tongs in cheek, like if you're not in peek condition we recommend sizing up.

Ah, I did read that, when I tried both the Classic and Pro Team bib short, the former fit perfectly in Medium, but the latter being a "race fit", fit better in Large, can fit a Medium but that required me to ride a bicycle with a massive saddle to bar drop to be comfortable.
