I tried Googling this, but I don't see it addressed even on Sheldon Brown's pages. I've got a very basic question trying to interpret the labels on my tubes and tires. I realize (from reading Brown's pages) this is a very non-standardized area and very dependent on the manufacturer, but my question is general enough that I hope it will be easily answered here.
My mountain bike tire says "26 x 38/32". Obviously the 26 is the diameter, but what is the "38/32"? It would be a non-standard fraction, but maybe it's just an easier way of writing "1 6/32" as the width? Or is it not a fraction, but maybe a range or something? But the larger number is listed first, which makes it seem odd for a range. And a range of what units?
Similarly, two tubes that I have for a 700C wheel are marked "700 x 28/32C" and "700 x 35/43C". Again, fraction, range, or something else? 43rds? Plus I wouldn't expect imperial fractions mixed with metric measurements. At least interpreting them as a range of millimeters seems a little more believable here.
I always seem to get stuck on the simple things...
