Shimano Dura-Ace R9270 C60 Tubeless CL Disc Rear Wheel

Shimano Dura-Ace R9270 C60 Tubeless CL Disc Rear Wheel Designed specifically for Shimano 12-speed systems; the Dura-Ace R9270 C60 Tubeless CL Disc Rear Wheel is extremely aerodynamically efficient and laterally rigid. The 60mm deep D2 rim has been wind-tunnel developed and slices through the air with ease; making it ideal for time trials; triathlons and flatter criteriums; while the cross-section is more stable thanks to a re-design. The 28mm wide external rim maximises air volume within the tyre; creating excellent traction and low rolling resistance; and is optimised for wider tyres between 25mm and 32mm. Being tubeless-ready; you can benefit from smoother rolling and better puncture resistance. The 24 spokes are stiffer than others in the range; bringing more lateral rigidity; and they’re laced to a premium aluminium hub that brings instant engagement for a highly efficient complete build.
