Went out with a mate from work on the road tonight to Whitewell. He had a puncture at the wild boar park (his first ever ride in the dark) it was chucking it down and cold. He dropped his tyre lever and couldn't find the damn thing. Anyway we got the tube in and pumped it up. There appeared to be a couple of solid lumps in the tyre. Good job we spotted em since it was the tyre lever. What are the chances of it falling in a narrow racing tyre haha!
