If I check my spacing and its about 4mm different from the new wheels I'm looking at, can't I just wedge them in? What's the harm or rather, when is it too big a difference to be an issue? I feel like if my spacing is 122 rear and 96 front, a set that's 126 and 100 should fit with a bit of elbow grease, right? I'm going to take the bike apart today for a thorough cleaning and check measurements before Ilorder the wheelsets
