Buleste: It was accidental. My bike slipped on a very gritty and dusty road whilst trying to go round a corner quite fast. My brakes were a bit too worn out to slow me down enough but I didn't really want to squeeze them too hard due to the risk of skidding - not that that would have made much difference.

I've no idea what is going on on Amibay and can't be bothered to look at the moment. Is it something bad?
