All the wheels are 11-speed ready to go with the new components. The non drive side has been pushed out to 7mm to maintain proper triangulation, and the freehub body is 1.85mm wider. The new rims are called D2 and are 23mm or 24mm wide depending on the model. Shimano also gave them a deeper tire bed to allow the tire to fit snugly to the sidewall, not allowing a gap on the clinchers. These combined features balance frontal and side aerodynamics.

Shimano has gone out of their way to make the rims perform better and more comfortable. They have given a new profile to the deeper wheels to help offset the effects of crosswinds, and receive a new lacing and hub design to improve response and speed. The clincher rim weight comes in around 383g while the tubeless one is about 420g.

The 9000-series Dura-Ace hubs, like all of the complete wheels, continue to use Shimano's cup-and-cone angular contact bearing system. It's reliable, easy to service and Shimano says it's strong and rolls smooth. The big changes are the move to 11-speed and a full titanium freehub assembly like on the wheels.
