Thanks, Jeff and Mr. IGH. From what I can tell so far, per my LBS, limited tire selection is the problem. Saying that, I'll keep rolling on what I have, because it's not an unbearable situation. It's generally a fun bike as is, that's for sure.

Quick question on steel wheels more generally (forgive the noobishness please): My understanding is that most steel wheels have been heavy stainless steel or chromed items. Has anyone made - or is anyone making - wheels using Reynolds 520, 531 etc., or other high grade chromoly steels?
