it seems to be rather quiet here, but going to try my luck anyway...
i’m having a bit of trouble with the press fit bottom bracket on my quantum. now had two different reputable lbss install new bearings. both sets of bearings have been the same type as the original ones were, by FAG and SKF. the first set was fine for a while but eventually started screeching and i thought it had sucked mud/gravel in somehow. was recommended to have the bearings replaced despite them being pretty new.
got the bike back from another shop today and the screeching started right away. tried to spin the cranks at home and the bottom bracket is giving the same screeching and even clearly resisting movement.
is there some kind of a trick to make it spin freely and silently? could (over)tightening the cranks have damaged the bearings? let me know your ideas before i start seriously contemplating facing the bb shell down to 68mm and installing the phil wood press fit bb...
