That's good info Gregster, thanks.
The other day a couple of us were riding between beer stops and calculating speed/rpm in reference to a 18 toother and the belt drive. My belt gives me almost identical, if not slightly higher speeds, as the 18 in your chart. This is by indicated mph on the speedo, which we all know to accurate to 1/100000th of a mph eeh?
And is was also identical (close enough) to mike on his BA with the 18t.
