I was thinking the same thing a few days/weeks ago. I want to do something weird with a IGH that has a FW or cassette on it and was thinking a 650b might be interesting.
Not to hijack your thread.... but what is the real difference between 650c (like small road and Tri wheels) and 650b? is there a diameter difference or does the 'B' just take a bigger tire?
