Heard a worrying noise from my rear left tyre, got out and it was flat arrhhh!! So I proceeded to get the spare and my strong arm for whipping the bolts off and I managed to pretty much round the locking bolt off. So I scambled home on the flat, only 1/4 of a mile from home thank heavens, and Ive got a locking bolt that dont wana come off with its key. Any suggestions on how to remove the swine? Drilling maybe? Im scared of taking my lovely anthresite paint off my rim arrhhhhh FML.
