We had a guy I've not met before with us today. Other folk knew him, so I don't know where he's been hiding the last 8 months that I've been going out with them. Anyway. He was riding a vintage steel bike that he'd refurbished himself, having bought the frame on ebay and driven to London to collect it. It was a 531 frame with lugs, rather than welds, like rogan's fancy frame. It had downtube friction shifters and the groupset was all old 8 speed Campagnolo, which he'd struggled with, just by virtue of trying to find such old compatible parts in good nick. He couldn't get a compact upfront, though he had managed to get to 52/39 from the 52/42 it came with, and it only went to 26 at the back, so it's a good job we didn't do much in the way of serious hills! He was pretty handy on it, so fair play to him.
