Thanks. I already looked at that page, wihch is why I asked here. The frame in question is a small road frame. I would not want to mount true mtb tires on the bike, but if equivalent road tires are available they would do nicely. I know there are some 650B enthusiasts here.
The other half of the problem is brake reach. I thinking there isn't so much difference between the various nominal 26" wheels that I couldn't find something. But is always better to know than to not know.
