Dobber: There are two cartridge bearings for each cup and a spacer sandwiched between them, I'm not sure how to explain it any better, but the spacer is what allows you to adjust the preload on the bearings by tightening the cups. This spacer can be moved with force along the spindle, thereby adjusting how far the spindle is inserted into either cup and modifying the original chainline.
Is this an outboard bearing?
I'm thinking of the plain vanilla bottom bracket. Two cartridge bearings, an axle and a housing.
This is Africa, 1943. War spits out its violence overhead and the sandy graveyard swallows it up. Her name is King Nine, B-25, medium bomber, Twelfth Air Force. On a hot, still morning she took off from Tunisia to bomb the southern tip of Italy. 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.
