Campy and Shimano wheels are a cut above the rest in terms of lateral stiffness due to their unique spoking patterns. They use seven spokes on the NDS and 14 on the DS. Because on the DS the spoke angle is small you want more spokes on the DS as more spokes increases lateral stiffness. The seven spokes on the NDS are sufficient because they are able to increase the flange spacing on the NDS to compensate for the low spoke count. What you end up is a wheel with high lateral stiffness. I think I read somewhere that 13 World Tour teams ride Shimano wheels. That speaks volume on the durability and functionality of their wheels.
Before you make a decision wait until June 29th to see if new wheels are part of the Dura Ace new product offering.
While Shimano Wheels are alright, using the 'what pros ride' argument is a poor barometer of equipment performance.the fact that 13 Worldtour teams ride their wheels means NOTHING to us. Pro teams ride what they are paid to ride. Teams get a preferential package when they agree to ride the full suite of equipmen form one sponsor. Shimano gives better terms if you ride their groupsets, wheels AND components. they won't let you ride their groupset ONLY. same with Zipp and Campag. For other teams with their own wheel sponsor hey get paid more than shimano or campag or sram will pay them, so they buy their own parts.

So saying shimano wheels are good because proteams ride them, is frankly, BS.
FYI, my sponsor shop hosted some orica riders 2 years ago. I won't say who, but they outrightly say they did not like shimano wheels.
