Hi Team,

I can't see to get the lock ring from the non drive side of my bottom bracket so I can service it.

It just won't seem to move. Anybody had this?

BB are notorious for getting stuck, leverage is your best bet. get a breaker bar as long as you can manage and give it as much grief as you can without damaging anything.

giving it a good soak in plusgas would be helpful too. you might need to resort to heat if it doesnt budge, then chisels etc when the edge gets too chewed up.

Chisel and sacrifice the lockring then remove bb in usual way.

Sometimes they get ovalised.
A quick tap with a centre punch or small chisel might just be enough to move it without destroying it.

At least get a lock ring spanner that fits.

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.
