The Mega has come out ahead of a trip to Spain and I'd clearly forgotten it had a creak when I put it away after last years trip (the e bike/injury means it's not been used since. At BikeParkWales the mechanic checked the bearing torques and a few were low which solved it, but it came back within a run.  

there are a few reports of really short bearing life from the OEM Nukeproof bearings. the bike's probably only had c30 days use but that's not necessarily a good thing (especially if the bike gets washed and put away) and they've been hard days.

The Nukeproof site no longer has frame info.  

Are my bearings likely shot? (I will strip it and check but if it's likely I can get away with retightening with loctite would be nice)

What are the specs? (I'd like to check if I've got presses/extractors that will fit)

Current recommendations for suppliers (Kinetic are twice the price of Trailvision for a full set)?

Any other wear parts when replacing?

Thanks @nwgiles, but that doesn't answer the questions. I'd found that, it says you get 10 bearings but not the sizes of them.  

I doubt I need a full kit, and I want to work out what size presses/extractors I need.

update for future searches.  Bought a full set, fitted most, only a few were showing any signs of wear. Original OEM fitment were all Enduro branded (which is what I used to replace them)

how old were the original bearings? surely as you had them all it's worth replacing them all?

They hadn't had a huge amount of use.  I only did the one of the 4 chainstay bearings that was noticeably worn (as these are a bugger to get out)
