Thanks for the input. I can't believe it, but the rear tire I have on the Bianchi is a Primo Comet. I got it for $3 at a thrift store attached to a quick release rim and a fork. I still haven't figured out what that fork was for, but I figured even just for the tire $3 was a good deal. Of course the wheel will also come in handy someday too. I was pretty excited when I inspected the tire closer and saw it was a high pressure tire. I need to find a match for it and I also need to get a new set for the Dahon. I stole a tire from my trailer to get it rideable.
