Hi,

I have a couple of questions concerning the compability of my BB and my crankset:
1. I have a shimano BB - UN51. how do I find out how it is threaded?
2. I bought a Campa recod pista crank (FC01- RepI549). is this compatible with the afore mentioned BB? Or do I need a certain spindle length? length on the shimano is 110mm
3. anything I need to be aware of befor sticking them together?
thank you for all help...

It should say on it, no?? Try putting it in your frame gently and if it goes in its the right one, if it binds do not force it and check carefully....

110, might be a little long for a pista, you can get away with a 103 normally I think, but it should still work though your chainline might be a little funky. It certainly wont be too short which is the good news....it really depends on your frame, rear spacing and how your rear wheel cog/freewheel is set up...try it gently and worst case scenario you have to take it off and fiddle with it :)

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.

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