I'm not talking the new-fangled external bearing systems. Your ordinary, run of the mill cartridge bottom bracket is basically a steel or aluminum tube with bearings stuck in either end. There is no way for the solvent to make its way to the bearing from inside the bike frame.

An errant piece of flak tore a hole in a wing tank and, like a wounded bird, this is where she landed, not to return on this day, or any other day.
