Got a mafia bikes 24 bmx thing and the bottom bracket bearings have welded themselves into the frame!

And tips for getting them out? it is currently soaking in white spirit... But has been for a few hours and I couldn't bash the bearings out.

It's probably threadlocked, if its fairly new, and you'll need to heat to melt the sticky shit.

It's not that old a bike, but was mistreated by previous owner. I think it's rusted on but I will give hairdryer a go!

it worked for me when removing a 25 year old BB.

Smash the crap out of it with a hammer and some kind of drift.

Best scenario, bearing pops out in a 1er. Worst, the centre come out the bearing releasing pressure on the outer ring and making it a lot easier to remove.

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:

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

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