I measured but does any one know what the size is? I cant find any info on it. I just wanna double check before i buy something off line.

I live in the middle of no where with no bike shops near by.

Also Good brand recommendations are welcome!

Thanks!

Measure it? You say you have done this already!, it's going to be either a 68mm or 73mm shell + the spindle length, alternatively, if you are planning on doing the work yourself (sounds like it), just remove it now, and the specs should be printed/on a sticker on the center section of the BB.

For brands, Shimano model UN26 for budget, UN54/55 for a bit better.

British thread Standard by BB shell width and in a certain overall spindle length you derive by Removing it whole BB and measuring

Shimano common cartridge bearing square taper BB have a label on them to Read.
