Not sure what you are referring to as far as noise from a Cooper!
It's not about noise from Ron Coopers in general, it's bigbossman forever giving me rations of, um, fertilzer for a noise eminating from the bottom bracket of
my Ron Cooper in particular, a noise I have yet to ID and rectify, much to his amusement. Between that, his carping about my bar-wrap jobs and saying that some people shoouldn't be allowed to have nice things whilst rolling his eyes in my general direction, I have a moving soundtrack every time we ride together.
But I make it up to him whenever he rides on my wheel, if you catch my, er, drift . . . .
