Shimano Ultegra R8170 C36 Tubeless CL Disc Rear Wheel
An ideal addition to any premium road bike build, the Shimano Ultegra R8170 C36 Tubeless CL Disc Rear Wheel features a stiff and aerodynamic carbon rim, paired with a rapid engagement hub for near-instant acceleration. One for the climbers, the 36mm height combines speed with lightweight performance, making this rear-wheel an exceptional all-around choice. The rim profile is shared with its more premium, Dura-Ace equivalent and offers tubeless compatibility for ultimate speed and efficiency.
Weatherproof Labyrinth double-contact seals limit water ingress to extend the lifespan of the bearings, and Borozon treated races reduce friction for a ride free from drag. The combination of elbow-less spokes and wide flange spacing offers exceptional lateral rigidity without compromising fatigue-reducing compliance.
