Then click "enter"
Under "Theme", click "Mavic Rims"
Then under "Family" click "Road & Triathlon - Multiperformance"
Then under "Product" click "Open Pro 05"
Click "General Points"
"Respect the appropriate spoke tensions; Mavic recommends spoke tensions between 70 and 90 kg (for a front or rear wheel on the free wheel side with a crossed 3 pattern). Inappropriate spoke tension can generate too much stress and damage the rim"
I tension my 3-cross 36 spoke Open Pros to 110 kgf for front wheel spokes and rear driveside spokes as well biked says he got on the phone and have never had any rim damage resulting from those spoke tensions. I think the 70 - 90 kgf is very conservative.
While you're at the tech-mavic.com website, download the whole 2007 technical manual for future reference. It's a 4.6 MB (37 pages) PDF file, and an excellent reference.
EDIT - The attached document "Spoke Tension" from the tech-mavic.com website says tension on front wheel and rear wheel drive side spokes should be 90-110 daN. Does anyone know if kgf and daN are the same? Never mind; I found it in another document on the website: 1 daN=0.980 kg.

That's great info, Scooper. So the recommended tension for rear driveside and front spokes is 88.2 kgf to 107.8 kgf (converting from the daN figures). Do you know if that's for all of their rims? I wonder why they have the other figures listed, the 70-90 kgf. I think that would be significantly too low (particularly the 70 kgf figure) for the rear driveside.
The rims I asked about on the phone were Open Pro, CXP-33, A719, and the now defunct X517 mountain bike rim. The Mavic tech guy on the phone said to try and get an average tension of 105-110 kgf on the driveside rear for all those rims, regardless of spoke count, and all would be good.

No one appreciates Sheldon's fantastic depth of knowledge and his ability to share it so it makes sense more than I, but having him list every rim manufacturer's spoke tension recommendations for all their rims would be asking too much.
