Advantage of Dura Ace hubs vs Ultegra w/Mavic CXP33 build(8 posts)

Advantage of Dura Ace hubs vs Ultegra w/Mavic CXP33 buildt-moore
Oct 5, 2003 9:43 AM
I am about to replace my Cane Creek wheels with the CXP33's, are the Dura Ace hubs worth the extra money. My Cane Creek's are relatively new, but the rear drive side spokes are pulling thru cracking the rim.

I guess it offical, I am a 6'4" 240lbs animal....

The Ultegra hubs use 2.6mm spoke holes and the D/A uses 2.3 mm. A standard 2mm spoke fits the D/a properly and the Ultegra loosely. This can lead to spoke breakage over the long haul. Since you are a beast, you might go with the Ultegra and opt for the Alpine III spokes. They are 2.3 mm at the elbow and very durable for "special" applications like yours. Both hubs are very high quality and are sealed well against the elements. The Alpine III spokes are closely matched in weight to the normal DB spokes, so there is no great penalty there. You might consider the new Velocity Aerohead OC rim. It can be built with more even spoke tension, which is important for you.

Are the Alpine III spokes a lot more expensive than the DT spokes that are more commonly used. Above did you mean to say that the standard 2mm spokes fit the Ultegra properly and the Dura Ace hubs loosely. I thought my Cane Creek wheels used a Aerohead rim. I am familiar with the new Velocity Fusion rim, but not the Aerohead OC......

First, have you checked into getting your old wheels either replaced (possibly under warranty) or just rebuilt? Or are you just going to trash them? If so, I may take them off your hands... I can rebuild them pretty easily.

Next, the spoke holes for Dura-Ace hubs are slightly smaller, so regular spokes fit better than Ultegra.

And last, my opinion, if you can afford them (they are quite expensive) is to go for Sapim CX-Ray spokes. They are the strongest spokes ever tested. They are bladed for aerodynamics, but they are strong enough for downhill racing. Yet they are almost as light as titanium spokes. The catch is that they are almost $2.00 per spoke. But if you can afford that, they are by far the best spokes on the market today.

I bought the set from SuperGo here in SoCal, and I am just going to take them back. This was my second set, and I guess it is now offical, I weigh too much for the wheels. Before I bought them, I called Cane Creek, and told them how much I weighted. I was told, they had guys weighting 270lbs w/o any problems. The system wouldn't allow me to upload pic's of the whee, but over half of the drive side spokes have cracked the rim, and started to pull through.

......and its true there are guys your size here who use the CC wheels without issue. Make sure your using the Stainless Steel spokes and NOT the TI spokes. With SS you should have no problems. But if your set on it and money is an issue I would take the advice above

spokes pulling through the RIM would seem not to be a factor of rider weight (breaking spokes, yes). it's probably a defective rim, or too high tension. I'd ask them to rebuild the wheel, then perhaps you might want to sell it.
incidentally, are the pull-throughs on the drive or non-drive side? a friend just had CC rebuild his wheel with an Aerohead OC. definitely makes for a stronger rear wheel.

YEs the Alpine III spokes are more expensive than normal DB. And the spoke holes in the Ultegra are larger and standard DB spokes are not the best fit in those hubs. I know that there are millions of these spokes in those size holes, but that does not make it optimum. You require optimum+. For long time durability, I would encourage you to go with a 40 hole rear wheel or a 36 hole with a high profile rim like a Velocity Deep V.
