I have picked up a cheap Shimano RS700 Flat Bar Rapidfire Shifter as I’m building up a 1x On One Inbred 26er for my youngest.

Can I use any 11 speed derailleur with this shifter? Ideally I want to give them MTB gearing.

Cheers

How MTB-ey do you want to get?
R7000 RD can handle 11-40t and you can get a wolf tooth extension if concerned or wanting to go a little bigger.

We are very hilly around here in Stroud, so if I could go bigger than a 40 that would be good. Though I could go small on the chain ring I guess. They won’t be going fast, but want to explore the off road stuff around here.

Happy to be corrected, as far as I know, road to mtb isn't going to work without a cable pull converter. Be cheaper to get a MTB shifter.

Thanks. Thought as much. I guess a GRX would go up to 42, so that’s an option.

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.
