2025年2月19日 · Bicycle Mechanics - Bottom bracket spindle width 113 vs 115 - I have this project bike. A bit of a beater and I’m trying hard not to buy new parts but rather put it together using my parts bin. It’s a single speed, running with a freewheel. The old bottom bracket (square taper) which is shot, was 113mm spindle. I have
