Bike Anti-Porn - When Things Go Wrong

Get your tape measure out, that stem looks more like 70mm, given that it starts 50mm in front of the steering axis due to the Look hinge fork. Still wrong, just not as wrong as you think.

Tis misleading, that headtube. Only serves to make the fitt look all the worse.

No, sure. It looks (no pun intended) a size small for the rider, although the reach would suggest he/she either has a pretty poor road bike position or needs a much shorter top tube.

Pure guesswork. But that looks like tri frame, built-up for road cruising. So it may be more a case of inappropriate geometry than inappropriate size.
