400ex Biopace chainset in good condition. Outer 52t chainring only, fitted with short chainring bolts. Intentionally converted from the original two speed setup a while back. In good overall condition, chainring runs absolutely fine, teeth in good nick.
Will double check crank length but I think it’s 170mm.
PS Just in case you’re not sure, you don’t have to stick with the biopace ring, can replace with any 130bcd ring.
PM if interested, can collect from Tower Bridge or Highgate Road
OP hasn’t been on here for over a year and the thread is 7 years old. I’ve got a 300ex I’ll ship to Holland pm me

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
> Quote text by starting lines with >

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

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