Wheel building query - Where do I measure various things from?

Ok, I'm about to rebuild a pair of wheels. Not my first build by any means, but this will be the first time I've dished anything, and the first time I've not used new components with full datasheets. (40h high flange tandem rear with 5speed screw on block and a hub brake built in, being laced to a 40h Rigida Sputnik, same for front, with no hub brake or block, duh.)

The hubs aren't new, and I don't know what they are so, I need to know where I measure things from. I have my vernier at the ready. Can I get some reassurance that I'm doing this right please?
- ERD for a sputnik is apparently 600.0mm - http://lenni.info/edd/rim/1006-rigida-sputnik-700
To measure the flange diameter, it's the distance between the centers of opposite spoke holes on the respective flange?

Centre2Left and Centre2Right are measured by finding the centerpoint of the hub (as in mid point between the dropouts, I assume?) and measuring centerpoint to respective flange, parallel with the axle.

Many thanks.

ERD sounds right, if full size of 700 is 622

flange width doesn't play a big role, but flange diameter does. should be able to use the same length spokes for both wheels, just tighten them more on the block side (if thats the dished one)

The hubs are different. front has a much lower flange. Should have said.

Thanks for the response, I'm really just looking for reassurance that I'm going to measure the hubs in the right way...

could build the front x4 and rear x3 (actually am i being too crafty)

I could. I'm still considering exactly how to go about the build. I've never done a 40h rim before. I'm probably just going to do a direct copy of what's already there. It's a tandem, see.

Thank you. That's exactly what I was looking for. I knew something like that existed, I just couldn't find it...

I knew this forum wasn't just mudflinging, crap jokes and beer... :)

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

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.
