Mrs. GA off with her school chums, so I had an XL fettling session after a flat on my ride with the Trek 7200. I replaced some broken spokes after removing cassettes from 2 wheels with broken spokes on the drive side, as I had the breaker bar and cassette remover out anyway. I replaced the broke spokes on the 7200 rear wheel, cleaned and regreased, while it was cassetteless. I trued the wheel very closely, as I ride with a narrow brake gap. I also put a new tire on, as when I bought the 7200, it had a very thin tire on rear, almost new on front. I had this occur with another bike previously, and it was the same tire as this tire was, by my good fortune, so I added that one to the rear wheel I also fitted a new SRAM shifter and a bottom bracket to my Trek/Gary Fisher Marlin, as well as cranks. New tires (Hutchinson Pythons) and the other shifter may go on today.
