It's not as simple as that, it's a personal thing. There is no gearing that is suitable - some people ride very high gears like 48/14, which I would find incredibly uncomfortable, for example. However, a good ratio to start with would be 48/18. You might want to go higher (buy a smaller sprocket, say 17), or lower (19).

42x16 is similar to 48x18 i think...

here, try http://software.bareknucklebrigade.c...it.applet.html. In terms of gear inches, you'd probably want to be around the high 60s and low 70s.

yeah the difference is negligible they're both 70ish in terms of gear inches.

Link didn't work for me. Try this one:

You'll need Java installed...

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.
