Actual ERD of Mavic XM 719 disc rim??
Does anybody know the actual ERD???
I have seen different meassures of 532, 536 and 538
But which is correct????
All I can offer is that Mavic says the 'spoke support diameter' for both the disc and non-disc versions is 536mm... so that's probably wrong.
Mavic's numbers are usually short, so I'd bet on something greater than 536mm.
The only way to know for sure is to measure it.
