Would normal V-brakes work, on a 650C frame with a 700C wheel? And what if I put a 26" wheel on a 650C frame, would that work?
I have never seen a 650C wheel in my life, I think.
There's no way you are going to fit a 700c wheel in a 650c frame. 650c is ISO size 571 mm and 700c is ISO size 622 mm. That's a 51 mm difference in diameter and about 25 mm difference at the brake surface. A bike built for 650c wheels won't have a v-brake/cantilever brake mount that I've ever seen.
A 26" mountain wheel is ISO size 559 mm which is only slightly smaller than 650c but the wider build of 26" mountain wheels is going to be too wide for narrow racing forks used on 650c and actualy although the rim is slightly smaller in diameter I don't think the wider 26" tires are going to fit anyway.
Actualy this is all a bit academic anyway because why in the world would you want to fit the wrong wheels anyway?
