I can't compete with all these lists of breakages, but I did manage to snap a crank once, and this time I really really was 'just riding along'. Well, I pedalled a little bit harder to get up a kirb: I was meeting people for a ride, so I just pushed the bike up to them and asked if there was anything wrong with my bike, took them at least a minute to realise I only had one crank Ended up borrowing someones spare for that ride, only it was 10mm too long. Pretty funny to ride like that although not exactly practical! Oh yeah I think the crank is a shimano stx rc if anyone remembers that. [edit] eek, didn't mean to resurrect an ancient thread, I was running a search and didn't look at the last post date.. sorry [/edit]
