Translation:- none of the moving parts on the bike have ever seen a drop of oil or grease in the last 30 years. It has now got so bad the balls have started to fragment and chew the bearing surfaces in the hubs to bits.
Some years back a friend said his pedals were "wobbling"😁
Bring it round I said, I regretted that invitation for days after.
I'd never seen this bike before and asked him if he had submerged it in salt water just to annoy me.
When I coaxed the BB out with drifts (cutouts for a hook key long beaten to death) and some flame I looked inside.
About 1/2 the balls had escaped the races as lumps and smoothly worn hemispheres. All of it black in colour with a coating of what could best be described as grinding paste.
