The Racing Zero CMPTZN Disc Brake Wheelset combines the storied Racing Zero rims, with a disc brake compatible hub, and the highest quality CULT ceramic bearings, making them the very top of Fulcrum’s disc wheel range. With a 19mm internal width and two-way fit to mount clincher or tubeless tires, these wheels are a versatile and lightweight upgrade to your racing steed. The combination of ultra-smooth ceramic bearings, balanced and uniform carbon construction, and the 2:1 spoke lacing create a stiff wheelset that still delivers a ride quality to keep us rolling for all-day races. Our power means more when transferred to the stiff and responsive rims, while the bearings’ smoothness ensure we can go further with less effort.
