I recently got a Genesis Datum frame to replace my cracked equilibrium. It has a shimano bb86 bottom bracket fitted, which i need to replace with a gxp equivalent.. I bought a Pro Bearing removal tool, inserted it according to manual and hammered the shit out of it..bearing does not move at all..Wrong tool, bigger hammer or bring bike to bike shop?

I don't have BB86 experience but I had the same issue with BB30.

Then I realised there was a circlip inside to hold the bearings in place.

The removal tool was hitting it instead of the bearings.

thanks, will check that again. I didn't see any clips in the manuals i checked but who knows.. Will probably buy a Parktool bb90.3, which should do the job..
