A friend is trying to convert a bike to singlespeed and has acquired a wheel designed for a screw on freewheel. While trying to buy a freewheel for it, we've come across the issue of metric vs imperial threaded freewheels, and I can't seem to find any information about the difference. What is the difference between them and which kind will most likely be required on a standard wheel designed for a screw on freewheel?

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.
