What is the ERD of a Mavic XM 317 rim?
I'm using Ramon Rinard's spoke calculator but that particular rim
unfortunately isn't in the databaseand Mavic's website is not helpful.
I'm building it with a Shimano XT (HB-M760 hub), 3 cross.

Thanks

JB

Actually, you may as well teach the man to fish as well...how do I
measure the ERD?

Disc or non-disc? The Disc version _is_ listed in Spocalc at 538.5,
but the non-disc version isn't listed.

I have a couple of wheels I built with the non-disc version. I had an
X221 that a side-by-side comparison showed to have "pretty much" the
same ERD, so I used 543.5. Like I say, I've built two fronts with that
figure (with and without dynohub) and both came out beautifully.

And buy your spokes from Dave on ebay - best deal in the universe.

I think it's 539.5mm

You need the "tech" mavic site:

http://www.tech-mavic.com
login "mavic-com"
password "dealer"

There's a pdf there for the XM317, which says the "Spoke support
diameter" is 539.5mm. Or 536mm for the XM317 Disc. I'm hoping "spoke
support diameter" means the same thing as ERD.

I'm getting the parts for a new front wheel for my mountain bike, and
chose the same rim and hub as you. Hunting around on Shimano's website I
found these measurements for the HB-M760 front hub:

Center to flange: 35.8mm
Spoke hole circle: 38mm

That makes the spoke length 262mm for 3 cross.

I get 264mm for the non disc and 263mm for the disc rim.

Could be you're calculating for 32 spokes? I get 264 and 262.46 for 32
spokes non disk and disk. For 36 I get 262 and 261. I should have said
262mm was based on 36 spokes.

That's also with a 2.6mm diameter spoke hole which makes a small
difference (I think you just add half that, so 1.3mm, at the end of the
calculation).

Thanks everyone, It is a non-disk hub (I thought the model number
includes some code that indicates that.). I'm doing 32 spokes 3X.

Going fishing now.

I see you're in Western Springs. Can I save the $9.00 shipping charge
by just driving over to your place to pick up some spokes?
