Good morning everyone,

What spoke tension should I use with Camgnolo Centaur hubs (old style), 14/15 gauge db DT spokes, with Mavac CXP33 rims? Im at 100 all around now in the front, using the Park tension gauge, and Im just starting in the rear.

Rich, last time I checked you could get the specs off Mavic's website.

Recommended tensions will be inside.

Now that I can get into there site, I went through the whole thing and I couldn't find the spoke tension for the Open Sport or Open Pro. So far what I got off the forum is anywhere from 70 to 110.

I'd take the Open Pros and the CXP-33s to 100-110kgf.

The site does have a spec though: http://www.tech-mavic.com/tech-mavic/technical_manual/data/docs/products/2_119.pdf

They say 70-90kg, which seems really low to me. Maybe the kg doesn't translate to kgf 1:1, but I don't see a quick conversion on that. Kilograms of tension makes no sense at all, so it's odd that they'd use those units.

+1. I called Mavic a while back and asked them about Open Pros, CXP-33's, A719's (maybe a couple more that I don't remember), and the tech guy said 105-110kgf maximum tension on all those rims.

Thanks guys, that's what I have mine set at.

That's where I set mine and have over 40000 miles on the set and rarely need truing.

I'd love to get 40000 on the Open Sport rims, but I'm thinking about upgrading a little bit.

I have two CXP33 wheelsets built to this tension....no problems. Someone else could confirm or deny this, but it seems to me that 100-110kgf is a good tension range for building wheels with most basic road rims (mavics, velocities, etc.)

Agree, it's dimensionally wrong and not clear. Is there any way to translate to pounds? Is the conversion to newtons just (as usual) to mult by 9.8, or is it somehow implicit or obscure?

Park's site says, "One Kilogram force is approximately equal to 10 Newtons or 2.2 pounds force. As an example, a spoke tension is 105 Kgf. This spoke would be equal to approximately 1050 Newton or 210 pounds force."

I have a CXP33 wheel set that I built to ~100 and they're fine. I've used the same tension on a couple of A719 wheels, too and they seem bulletproof.
