So I was following some traffic pretty closly and didn't see the pothole stretching across the whole road. Maneged to lift my front wheel in time but my back wheel hit it pretty hard.
Next thing i know i nearly went over the bars because my back wheel pretty much locked up. Thought i'd killed the wheel but when i stopped to check it out it seems my seat stays pretty much swollowed my mud guard. Crap, now i'm mudguardless just when the good old blighty weather decides it's going to have a week of rain. Still, glad is wasn't a dead wheel that was causing the trouble.
