650A - the old 590mm size used on old Raleigh 3 speeds?
yes this begs the questions....
I'm hot to try one of these conversions... as soon as I determine if the frame (old Dawes Galaxy) is suitable, or I find another possibility.
The 650B is by reports, 588, right?
Well, wouldn't that 590 be about useable? Or does that number represent something else?
Would a 650B tire fit over a 590 rim?
(there seem to be a few 590's in the volunteer shop I work in... tho they may be old clunker steel ones?)
