I knew that it had been "bonded" and wasn't surprised that there was some creaking after I'd had it for a while. I didn't think anything of it when the mysterious creaking ceased whilst out on a ride one afternoon.
A couple of weeks later, whilst I was tail-gating a bus, the downtube decided to part company from the bottom bracket shell and the whole thing fell in half. It was at this point I was forced to use my knees as brakes. As I walked in through the front door at Wankworth Manor (my parents gaff) with blood pissing out of my knees, elbows and chin my mother was rather aghast at the fact that I was really pissed off because my bike was in two pieces.
So, whilst I would recommend owning one if you want to hang it on a wall, riding something that age would require a concrete sphincter.
There!
