I am working over the new 66cm Quickbeam, and saw the cranks were flopping, which turned out to be from a loose BB. It's a sealed cartridge Shimano unit, had been installed by Riv. I guess the rings came loose, and the previous owner hadn't noticed.
BUT... the left side ring is plastic, is that normal? And, it's split/cracked across the threads... is that normal? Or a sign of wear and fatigue from the floppiness? - Andrew, Berkeley -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
