So, I mistakenly thought the Surly Ogre would be 68mm bb shell, didn't measure it of course and bought a 1x 40T 165mm GRX crankset for it. It's not in its box but it's not been taken out of its plastic wrapping.

I need a 73mm shell compatible 1x crankset, preferably in 165mm also. Would swap 'em or buy it.

Thanks and fuck Ofcom

I've an slx crank, will check length but should be either 170 or 165. And a couple bbs if you needed too. Chainring is AB oval thing that might annoy you...

That'd be handy, thanks. I've got a new BB here already that I assume will work with it but I've fucked this up once already so now I'm doubting my ability to pick correct parts for anything in the MTB world. I should've outsourced the mini project to the hive mind...

I could use the oval ring for shits and gigs but would prefer round. How many teefs?

It's not something silly like Boost is it that will screw up the chainline or something else I've forgotten to take into account?

Maybe this is the time to buy a powermeter for my MTB and put my XT cranks on the Surly haha :)

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 >

Mention another user by @username

For syntax highlighting, surround the code block with three backticks:

```
Your code goes here
```
Just like Github, a blank line must precede a code block.

If you upload more than 5 files we will display all attachments as thumbnails.
