I'm heading out on my first longish tour and currently have a 23c spare (nice and light) folding tire to go on my Mavic A319's. The Mavic site says these rims are 19c and suggest nothing thinner than a 28c, which is what the bike is currently equipped with. Anyone have personal experience putting 23's on a 19c rim? This is obviously not a [I]great[I] idea, but will this work as a lightweight way of getting me through a day or two of riding to the next shop"
Thanks for your time.
