27 inch wheels and 700 wheels, what's the story?

I have been told by my dad, who was a racer back in the day, that all tubulars are 700 and always were, so if it was designed to take tubs rather than road tyres it will be 700. As it's a track frame I'd say that's more than likely.

Yep.. I'm a Dad'. And thats true. I can remember going from 27" totubular' (no other term around for that size) in the 70s and the wheels were smaller.. had to lower my brake pads etc. Not a Grandad yet but still trying to get used to the idea of 700 clinchers'. Back in the day that would have beenha hahaha... why?'=`wtf' today.
