would putting a u-brake in the canti mount will enable the conversion of a 700c frame with canti studs to 650b?
The difference in radius between 700C and 650B is only 19mm, the difference in brake stud position between cantilevers and U-brakes must be over 50mm. Putting a U-brake on your 700C frame's cantilever stud would place the brake blocks in about the right place to hit a 520mm rim, which is the "24-inch" size used for small road bikes, or maybe a 540mm which is "24-inch" MTB size.

just wandering, seeing the mount for u brakes are usually higher than Cantis.

Add: or centre pull is more accurate?
