The reason I'm asking is that even though I have a 61cm mercier kilo frame, 28s are even a tough squeeze-if I inflate the front tire to it's max, it hit's the top of fork crossbar or whatever it's call.

Wouldn't a 650c track/fixed wheelset make better sense for urban commuting? It would wind up quicker and there would be more clearance for fat ass tires like 32s or 35?

Help please!
