Threaded bmx bb was a thing for a while.

It was called 'euro' and it was pretty shit.

The small shell and large axle meant tiny bearings which didn't last long at all. I remember mates with euro frames going through a bb a week.

If you must do it, use a crank like a Profile that has a 19mm axle as opposed to cranks like Primos that use 22mm axle.

Ok seen a bunch of cheap ones with 19mm bb, bought a cheap fgfs frame and trying to build under 150

Sorry if this is teaching you to suck eggs but you know the cranks are unlikely to come with the bottom bracket right?

You'll need to buy the bb separately.

+1 for the Profile cranks. I use an Odyssey BB with mine, and other than a few creaks, no problems. Cranks weigh a fucking ton though.

Formatting Help

Don't worry about formatting, just type in the text and we'll take care of making sense of it. We will auto-convert links, and if you put asterisks around words we will make them bold.

Tips:

Create headers by underlining text with ==== or ----

To *italicise* text put one asterisk each side of the word

To **bold** text put two asterisks each side of the word

Embed images by entering:
![](https://www.google.co.uk/images/srpr/logo4w.png)
That's the hard one: exclamation, square brackets and then the URL to the image in brackets.

* Create lists by starting lines with asterisks

1. Create numbered lists by starting lines with a number and a dot

For syntax highlighting, surround the code block with three backticks:

Just like Github, a blank line must precede a code block.
