I'm wondering if this is a quality part? If so where can I buy another? If not can I just replace the sealed bearings? or upgrade the entire BB? I'll need to know how to measure the length, is it the entire length or ???
Thanks a bunch,
looks like a standard square tapered bottom bracket for a 73 mm shell, measure the total length of the spindle without nuts. take note if you have a centered spindle or offset. as far as brand that would be up to you. Do not know where u are from as you never told us in your Bio, its a pretty big world so get what is available where ever you are. it appears to be British standard you will know if you had right and left threading. Make sure you get one for 73mm shell and measure your spindle in mm too
There are two kinds of people in the world, "Those who help themselves to people, and those who help people!"
TH Industries makes low end components. They are a Taiwan based company. The BBs are not serviceable - replaceable only.
The UN54 that George suggested is a slightly higher quality bottom bracket; also not serviceable.
