Shimano Dura-Ace R9270 C50 Tubeless CL Disc Wheelset

Shimano Dura-Ace R9270 C50 Tubeless CL Disc Wheelset 

Engineered to deliver peak performance, the Shimano Dura-Ace R9270 C50 Tubeless CL Disc Wheelset sees an ultralight carbon construction for rapid acceleration and race-ready stiffness. Uber efficient, these wheels feature a redesigned hub with Borozon treated bearing races for minimal friction, as well as Labyrinth double-contact sealing to prevent the ingress of dirt and water. 

The rear wheel is compatible with Shimano 12-speed cassettes only and features a freehub with direct engagement interlocking faces for near-instantaneous power transfer. Lateral stiffness is improved with the wider hub flanges, while elbow-less, straight-pull spokes boost rigidity.
