• Knocking the bearings out would probably knacker them, so you can knock new ones in and see if it fixes it, before that I'd remove, regrease and refit all the other stuff first to see if it's them and check pedal threads and chainring bolts and your saddle, seatpost and rear skewer. If it is the BB then the thread together replacements from wheelsmfg or similar are better.

  • I've already eliminated pedals, chainring bolts, shoes, saddle, seatpost, stem and skewer, etc. I'm not Dammit, this isn't my first rodeo.

    I don't want to replace the BB. I've got a Park Tool BB30 bearing remover thing - I assume it works on the outside of the bearing so should leave the innards intact. I don't want to make it worse though. Maybe I could drizzle some shizzle on the outside of the bearing and note any change in noise.
