I have no issues with 650 wheels... my Trek 5200 47 cm had them and I am not any faster now on my Kuota with 700 wheels , despite what the LBS owner tried to convince me. I think he doesn't realize how old I am! Plenty of local supplies for 650 touring wheels at Harris Cyclery.
Well, we have to discuss how much we are willing to shell out. Both Seven and Independent Fabrication are local, as well as Peter Mooney. Denise G. has a very beautiful Peter Mooney bike I have seen sitting in her garage, but I've never seen her ride it.
