I dont know why you included that pic if it really measures out as 73 since it clearly shows its measuring a few mm less than 70 in that pic which confuses me .)

^^^ As he said. That looks distinctly like 68mm to me.

Morning Ben,

what chainset are you planning to use and what size is the frame ?

I have a number of Precursa frames and can give you some factual info once you post the details.

Regards Allister

you need one of these in 110mm :

about £15 no need to spend more in my view.

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.
