I wouldn't be surprised if the poll suffered from significant self-selection bias. I've only really had any interest in toe-overlap since I acquired a bike that had that characteristic a number of years ago. Prior to that I would have been unlikely to even open this thread, much less vote in the poll. But now that I have such a bike I'm more interested and did participate in the poll with a 'yes/60cm' vote although all of my previous bikes were in the 'no/>55cm' camp.
