Calling me a flat out liar?
Have also seen the same with a heavy duty tandem with heavy duty steel frame and 2.6mm / .105 guage spoked steel wheels. Bottom bracket with an injection port - nice smooth operation when operated by hand. Owner reporting clunking feel and sound...upon disassembly - despite what appeared to be reasonably clean grease or what others might call gear oil - spindle shot and one bearing completely destroyed.
I'm not an expert in lubrication chemistry and fluid dynamics...but I suspect some lubricants and weights can mask stuff.
Perhaps an expert will chime in?
