so, i have a bridgestone RB-1 with Suntour GPX 7 speed group. I wanted to put on a modern wheelset with shimano 105 FH-5700 10 speed hubs. will i be able to make it work if i put on a 7 speed cassette? the rear spacing seems to work as the wheels do go on without stretching the stays. if it will work, any recommendations on which cassettes? thanks in advance!
