i'm building up a cyclocross bike and right now i'm scouring for rims. i want to be able to ride a pretty skinny cross tire most of the time, maybe 30-32, all the while be able to put something super beefy on it: 40? anyway, i love mavic rims and am stuck on them and i would like to use the Open Pro. however, Mavic says the recommended tire width for the rim is between 19-28 mm. will it not allow for a larger tire? has anyone experienced otherwise?
