When wheel size says 20", 22" or 24" what exactly is being measured?
The reason I ask is that I just took a tape measure to my DMR transition which has 24" inch wheels and found that the centre to rim edge is 10.5" radius but with tyre included this takes it out to 12" radius, hence overall 24" diameter.
Sorry if this is such an obvious question, it's just that in all of these years I've never bothered to look and just took this for granted!
