Hey all, does anyone have any experience with the 2017-18 disc supersixes? I'm getting a monstrous BB creak (+some play I believe) and not sure how to fix it. It's even worse since I pressed in replacement bearings yesterday as the old ones were knackered.

Firstly does anyone have any idea what BB this is... I think it might be a wheels - it seems to be threaded so I'm guessing it isn't the original (FYI its been rubbed when I tried to use a FSA converter which did NOT go well - should be all black metal).

Unfortunately I can't remove it as I dont have a BB tool that large (48.5mm). I suppose it also could be loose after pressing yesterday

Options;

1. buy a tool, remove and replace with same BB + loctite/similar given I know the bearings are OK (+eventually have to buy a new power meter)
   
2. replace the BB with a new ?PF/BB30a (not sure which it is). Run the risk of it happening again (+eventually have to buy a new power meter)
   
3. replace the BB and switch to Hollowtech with my power meter + old crankset
   
4. pay someone to do one of the above just for piece of mind.
   
   

Any advice welcome!
