I'm in need of a seatpost for an old Clements frame I'm using for a new project.
I used the measurement I made of 84mm and this website... http://www.csgnetwork.com/circlecalc.html
And have calculated the seatpost that I need to be a 26.7mm post.

Is there such a size out there?

Probably 26.6 or 26.8: http://www.sheldonbrown.com/seatpost-sizes.html

I may have to buy both and see what'll fit, as my measurements may be slightly out.

Take the frame to a friendly lbs - mine had a selection of old posts to try and find the right size (I measured it with callipers at home, but they insisted I came back with the frame)
I was talking to them about the seatpost-sizing rods mentioned by Sheldon and they didn’t rate them as they don’t go down far enough to get an accurate reading

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.
