Anyone know where I can get hold of a 187 BCD ring for my old Ofmega crankset? I've been looking for a long time...

You may look for a long time for a 187mm BCD ring and then find it won't fit your cranks as they probably are not 187 BCD !

The obsolete Orfmega cranks are probably 118 BCD , it that's the case you may be looking at getting a ring made for you. Middlebaurn engineering and the Aussie outfit Fixamatosis will do this for you but is it really worth it ?

They're 187ish, bolt - bolt measures 110mm, and there are 5 bolts. I've never seen anything even close to this to know if there's an old standard size of 188, or 190?
I'm not forking out for a custom-made one, that's for sure, but on the other hand I'd rather not throw the cranks out...

I suspect it will be a fruitless search!

Middleburn and BETD are worth talking to about custom rings.

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

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

```

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

If you upload more than 5 files we will display all attachments as thumbnails.
