hey y'all, i have been riding a self made singlespeed steelframe touring bike for a few years now and have finally decided to go ahead and get myself a flip flop wheel. i am pretty impatient with wheelbuilding. i have 27 inch wheels, and found a 700 flipflop on the internet for 89 bucks. would switching to 700 be a big deal? would they work on a frame built for 27s?? - thanks -drew
