Should there be any play at all from the cranks? I have a hollowtech 2 BB. Noticed the creak after a particularly wet ride after deliberately riding through puddles (had to test my new mudguards...) Creak started off on the drive side, but now seems to be both sides, and i can feel some vibration coming through the pedals. Is this caused by the play in the BB, or is that normal, and it's my pedals that are the cause?
