tapering

A couple are from previous bikes, kept as spares in case they were ever to be restored, with the others bought new in a sale when it looked like square taper BBs were on their way out and awaiting their chance to be useful. An associate is building himself a cargo bike out of box section aluminium and asked if anyone had one of these lying around. Fortunately, I had seen them recently and knew exactly where in the loft to look.
