I just recently built up a Campy Centaur 9/10 speed hub on 36 hole Mavic CXP33 rims, with 2.0/1.8 double butted DT spokes. The dish on this hub is really pronounced, and the fact that these rims have no spoke offset doesn't make it any better. The tension on the drive side when the wheel is true is about 2x the tension on the non-drive side. I'm considering going to ligher spokes for the non-drive side to equalize the tension.

Opinions/experience with wheelbuilding and campy 9/10 speed hubs?

Thanks!

Sometimes you can space the hub more to the DS. But that can be tough/impossible with sealed bearings.

The problem with this approach is that the chainline will be affected. I guess these high-dish hubs really call for rims with large spoke hole offsets....

I have Campy hubs, DT Swiss 14/15 spokes, and Mavic open pro rims (like the CXP33) for my 10 speed bikes. Don't worry about the difference in spoke tension. Set the tension by tensionometer to meet the recommended overall tension and don't worry about it. I have a set of wheels I built that has 5.3K miles and I haven't had to touch them at all. Built them myself. No need to go to a different gauge spoke unless you like the look. Don't worry your rims are good and the spoke tension is as designed. I build my wheels on the upper end of recommemded tension.
Absolutely NO WORRIES with 36 hole wheels.

Campy hubs have the flanges spaced such that wheels built with them have lots more dish. I built a new rear wheel for my brother over Christmas, with his Campy Mirage hub (bearings still perfect after 12,000 miles) and a Mavic MA3. The MA3 has somewhat of a rep for cracking at the eyelets, and I was scared, so I built it with nearly perfect tension, slightly below the recommended limit, but since I made sure the tension was fully equal between spokes, I think it'll be totally fine. You've got more room for error: CXP33 is one of the strongest rims out there (can take higher tension than MA3 with no worries) and you've got 36 spokes. I think you'll be fine.

I agree with the above. If the Campy design were very failure-prone, you'd certainly hear about it.

Some people even take a standard campy hub and change it to radial spoking on the non drive side and 2x on the drive side...go figure. Still haven't heard of many catastrophic failures.

TallRider

Agreed. However, Campy could and should design their rear hubs so that the wheel ain't dished so much. Even though they work and are good as is, they could easily be better and stronger.
