I have inherited a set of wheels, the rear has an 8 speed cassette fitted, I have a spare pair of 9 speed Campag shifters, can I add a nine speed cassette to the wheel? Will that require a new freehub to work?

You'll need a new freehub.

PS What's the 8 speed cassette? Might be interested.

Im pretty sure 8 and 9 speed use the same freehub size. 10 speed is slightly bigger. I just directly swapped an 8 for a 9 on my 105 hubs.

8/9/10 use the same size hub, although you might need a spacer to fit. 11 is a different size but also fits smaller cassettes.

Ah, that's shimano only. According to Sheldon campag 8 speed and 9/10 aren't interchangeable

campagnolo 8 speed is different from 9/10 and 11.
you can use 9 speed ergo's but you have to put 9 speed spacers into the cassette in order for it to shift well (replacing the 8 speed one), it's a tiny bit out but it does work.

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

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