aww shiitt clefty! That's a worrying thing! What caused that? (so I can try and avoid it happening to me!) Hope you were okay, and in a safe enough position! x

Yeh luckily I was going rather slowly and up the hill rather than down, had the chain quite a while now, did remove a link a couple of months ago, but have given it plenty of abuse since then..maybe thats why. Its a strange feeling especially when you're clipped in, I still kept pedalling - I must have looked a right tool.

@Olly I've seen the guy on the blue lo-pro with the stubby bars, he's a curryer - lives just before the railbridge going into Colliers Wood.
