Trek 400d Bottom Bracket Size
Hi. I have a Trek 400d (86 or 87, I think). Does anyone know what size bottom bracket it uses? There is some play in the cranks, and the original bottom bracket is so old I don't think it would be worth it or possible to overhaul it, especially since I imagine the cup/cone would be damaged. It uses an SR SXC-200 crankset, which I couldn't find any info on. The reason I don't disassemble it and measure it straight away is because it's a lot harder to get to the bike shop on foot. Thanks for any help.
