Well I needed 40h rims for my sturmey 3 speeds and it was hard enough finding 40h rims in a normal size. + there are more choices in tires, liners etc.
I've now realized I could have gotten 40h EA3 tires but its too late and i already feel stupid, I thought 26" tires were approximately the same radius as 26x 1 3/8".

OK so how can I make my braking not suck with my 26x1.x" wheels on my calipers?
