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. ย 

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. ย 

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. ย 

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

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. ย I only did the one of the 4 chainstay bearings that was noticeably worn (as these are a bugger to get out)
