My BB sounds like it has a constant knocking like someone is bouncing a solid piece of plastic off the BB - knocking for the whole of my 40mile round trip commute.
It obviously isn't normal, but I just want to make sure what it is. With luck I should have a new bike in the next few days so if anyone reckons it should be OK for a while I'll live on with it.
Its many years since I tinkered with a bike and the last time I looked we didn't have BB's/cassettes - I think it we had cotter pins & ball-bearings.
Thanks
