I had a 31.6 Thomson on my CX bike, did P-R on it.

With wishbone stays too. I'm surprised you can still sit down, even now.
Cupcakes: another thing worth noting is that 105 5700 is an unsatisfactory combination with canti brakes. I'm not sure which version you were going for but if it's modern 105 with the hidden shift cables I'd think about using SRAM / Campag instead. Or pony up for some kind of cable pull adapter like a travel agent.
