Ultegra R8170 C36 Tubeless CL Disc Rear Wheel

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.
