Thanks for the info. I did some searching online and I see exactly what you mean. I guess I will be using some different rims on this next build, since I want to use wider tires than the 1 3/8. The main reason I had planned on using those rims was for the 3 speed rear hub. I will be changing everything on the bike, so I guess a new set of alloy rims is no big deal.
