Why the holes in old BB shells?
I never understood why older racing frames have big holes in their BB
shells. Is this to drain water, to allow flushing and re-greasing without disassembly, or just to look cute, with heart shaped holes and such? This always seemed stupid to me, because of road spray, etc. ??? Matt O.
