What size socket do I need to tighten a 1980s Campag strada crank arm that's come loose? The central bolt that goes through the middle?
Quick response massively appreciated.
Sorry to bang on about this but can anybody help me? I don't have the bike with me and I need to buy the socket. I think it might be 15mm but I can't be sure. Here's a pic if it helps at all:
