the only issue that i can think of that MIGHT come up is that there will be fewer threads for the freewheel to grab on to...i was going to do this last spring with a set of surlies and everyone i talked to thought it would be fine. the only reason i didn't do it is because my friend never ordered the hubs for me, so i just bought a set of phils with fixed/free rear. too bad i don't even use the freewheel side...now i'm wishing i would've gotten either singel fixed or dual fixed.

eh...live and learn i guess...
