pmt-
I am training on clinchers. Yes, I am really a "Try" Athlete with the emphasis on try. I have done some sprint triathlons and one olympic. The bike on which I recently flatted was a 12 year old Specialized Crossroads with baskets front and back. Not too racy! Right now, I am training for Ragbrai. For Ragbrai I will ride my Giant OCR 1, but I like training on the heavier bike sometimes to build up strength. And yea, I know I need to change my tire. Did it once and the thing blew right away anyway. And I don't like to break a nail.
