Bottom bracket, square taper upgrade?

[pat_h]

Re: Re:

To answer your question: no, it isn’t possible to upgrade from square taper as it hasn’t been bettered yet.

Brilliant reply! And considering it feels better at 27/28 years old than my 6 year old hardtails BB it's a valid claim

Re: Re:

Nothing to add to the above other than I would take the chance to remove the BB and grease the threads especially if you don't know the frames history.

That's probably a good idea, it feels solid if a little rough from lack of use. A good dose of grease could do wonders.

You can only grease the cup threading, not the bearings, since it's a sealed cartridge type.

Thanks, I'll do some studying on Youtube before opening it up

Re:

As above, stick with the square taper.

Re:

You could fit any bottom bracket that will fit in the BSA threaded 68mm bottom bracket shell.
Don't forget you'll need the cranks to match whatever bottom bracket standard you fit.
Square taper bottom brackets have been around a long time, and for good reason. They work. A newer bottom bracket standard may save a bit of weight, or increase stiffness, but I've yet to have any last as long as a decent square taper bottom bracket. And there's still a good variety of square taper cranks to suit a retro mtb.

As the BB seems OK, and as you already have the cranks to suit it, I'd be tempted to just remove it, clean and regrease the threads, and let it do its job for another few years.
You can only grease the external threads where it fits into the frame, it's a sealed unit and not meant to be opened up for servicing.

Take the bottom bracket out and grease the threads......no arguments....dont put it off....just do it. I have just done major surgery on the second frame in as many months with stuck and sheared sealed bottom brackets. This was due to unlike metal corrosion.

Cant say I ever had this on a non sealed old skool....even is you did getting it out after is a doddle compared with sealed.

Definitely on the greasing etc, will get a tool this week for removing it and give it a polish and grease.

You can skip the polishing bit, no one will ever see it inside the frame
