This might work assuming the lockring has enough support for the left side of the bottom bracket cartridge unit when used in wider than intended shell, but if you're swapping the crankset, it seems odd to use obsolete technology. Square taper bottom brackets have a flaw, namely that the taper is too small. This causes the spindle to break. Shimano attempted ...

The solution you are proposing isn't ideal but should work. However, depending on the bottom bracket unit, the non drive side "lockring" might have a shoulder on it, preventing it from contacting the bottom bracket main part fully and therefore not supporting it as well as intended. Many types don't have a shoulder and this is a non-issue in that ...

Amazing. Been trying to get rid of creaking for weeks now tried everything but the rear hanger mech. Removed it, bit of grease, sorted!!

I'm only dimly aware of Thompson bottom brackets, but: The visible thread on the spindle isn't a concern or a sign that something is wrong. My understanding is that, like Ashtabula/one-piece/American bottom bracket shells, the shell widths found on different Thompson shell bikes can have some variance due to either low tolerance or lack of real ...

The crankset should have a bottom bracket spindle length specification. I didn't see one listed in your link, but I don't know Polish, only Latvian :) Can you find out the correct spindle length from the crankset manufacturer? Either that or try to find a crankset that uses a 124mm spindle length. From my limited experience, 124mm seems like a long spindle ...

To elaborate a bit, I believe that the term mechanics or engineers may use is that the spindle is binding at a certain point in the rotation. As already pointed out, this isn't normal. I can only speculate on the cause without having the item in hand. However, all manufacturing processes produce variance in all their parameters. For example, the weight of ...

The normal "feel" of new cartridge bearing bottom bracket is a uniformly smooth roll that is quite resisted by the presence of grease within the cartridge body. One does not normally feel any grinding or a spot where there is any increase or decrease in the smooth but resisted turning of the spindle within the cartridge. Thus, I would be suspect ...
