I'm sorry it's taken me so long to mention this, but Los Alamos has a new bike shop: Little Jimmy's Wheel House. It seems like Jim is now doing bike repairs out of his garage, by appointment. He'll also order parts for you. He's got a pair of 700C reflective-sidewall urban slicks on sale right now that look pretty dreamy: I'm using 20" wheels now or I'd have snapped them up.
Best of luck with the new business, Jim!
