actually would be great to make the old junk work. I'm really tired of throwing perfectly good stuff away.
I'm really into re-cycling cycling.
For some minor plastic liner, a perfectly good BB should be tossed.
I can only imagine that whomever installed the BB, didn't properly tighten the cup, allowing the movement and the wear of the liner. The owner commented he had always had some 'chain rub' when he really got onto the pedals. I asked why he had never had it looked into? He said he thought it was just cheap junk and 'rub-age' was just par for the course.
I have some ideas... I might try refurbing the needed liner by using some p-tex. Properly applied, I'm sure I can get the cup to hold the spindle centered and rocksolid.
let y'all know how it goes...
