I've got a bike tire that says "(32-630) 27 X 1 1/4" on it.
I've got also got an innertube that says "700X18/23C -27X1 A/V".
I'm trying to figure out if the innertube is the right size for the tire. I gather that my tire has a 27" diameter and a 1 1/4" width. It seems that the innertube is designed for a tire that's 27" by 1"... which seems like it's not the right size. But is that correct? Or will the innertube fit? And in either case, what does A/V mean in this context?
