I'm new to bike forums. I just bought a Botecchia frame set and fork. I'm planning on building it up from scratch with all Italian componentry. Anyway, my first introduction to the project and community is to ask does anyone out there know how I determine bottom bracket size for this frame set? Do I measure the bottom bracket shell on the bike? Any collective wisdom you can send my way would be greatly appreciated! I'm looking forward to building up the frame and learning the wisdom of this bike community!
