Hey guys,

Newbie mistake, I bought a 10 speed wheel (Shimano RS80) to build up my bike with a 11 speed shimano groupset but just realized that I cant fit the 11 speed cassette.
I got confused as i'm used to fit 11/10/9 speed cassettes on 11 speed hubs but didnt realize the other way around wouldnt work.

Any known workarounds?
Thank you!!

You can machine an 11 speed hub to fit.

Looks like this user on time trialling forum might be able to help: http://www.timetriallingforum.co.uk/index.php?/topic/131800-11-speed-cassette-conversion-to-fit-on-10-speed-freehub/&page=2

Never used so can't comment on his work.

Thank you for your answer. I'll try to find a place in my town where I can machine out a few millimetres out of my cassette and hopefully someone to help me :D

You can also remove the same amount from the freehub body (instead of having a cassette machined). Can be done at home with a file.

You can use an 11-34 cassette (HG700 ot HG 800) 11 speed cassette on a 10 speed freehub

Can second @farewell 's suggestion. The material on the freehubs I've done this to has been laughably soft so it's pretty easy to do with a file.

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

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