WH-9000 CL carbon clincher wheels, designed to meet pro road race criteria. The design concepts of the new generation Dura-Ace 9000 wheels created products specifically engineered with attributes that are required by specific racing disciplines. The BLADE concept development is Shimano’s first fully committed effort to develop an aerodynamically superior wheel; the new rim profile is the result of countless hours in the wind tunnel and real world time trial and triathlete professionals’ feedback and validation. The accelerating SPEED concept is an evolution of one of Shimano’s original Dura-Ace guiding principles of delivering the most efficient power transfer systems in the racing world, by constructing ultra-lightweight, stiff and durable rims.
* Can be used for 10-speed with an additional spacer.
