Screw together bottom brackets - fit and forget?

Or do they need extracting, cleaning up and refitting every now and again? Got an annoying squeak coming (I think) from the BB area, but both of the bearings in the Wheels manufacturing BB feel OK. BB is about 3 years old (bearings much newer).

Wheels Manuf BBs come with an extra set of bearing seals which helps keep the crud out for longer, but the best way to preserve a BB is either not ride in the rain or wet, or stop them getting sprayed in manky water (fit guards). Slathering everything in marine grease also helps.

I had the wheels mfg pf30 thread together. Once fitted securely you shouldn't need to remove the cups since you can replace the bearings once in situ, with the right tools of course.

Yeah, I'm quite happy swapping the bearings, just do not want to have to take the cups out...

Only annoying thing with the pf30 one is that it needed a weird sized BB wrench which added further expense.

Not really fit n forget but if you ride in the dry then not far off!

The whole point of the wheels screw together is to eliminate the creaking normal PF bottom brackets are prone to.

But bearings are bearings. You’ll have to replace at some point but can knock out and replace just the bearings rather than the whole BB. If it went in properly and with threadlock on the shells i seriously doubt it’ll be the BB shell.

Squeak could be anything. And noises transfer! My MTB pedal bearing seals squeak until i squirt em with silicone spray. My road bike plagues me with a click in BB area that turned out to be a loose rear mech.

Highly unscientific but for my bikes bb shells normally creak, bb bearings click and feel grindy. Squeaking is normally something else.

I know, it's a traditional British springtime squeak hunt, have checked pedals, pivots, jockeys etc so far, still got BB and seatpost to exclude.
