R8170 C36 Tubeless Disc Carbon Wheels

The new Ultegra R8170 C36 wheelset is an upgrade for any road bike. Lightweight and race-ready, the Shimano Ultegra R8170 C36 Tubeless CL Disc Wheelset is designed for cyclists who want to gain precious seconds on their favorite climbs.

With a 36mm rim height, this wheelset is optimized for rapid acceleration and offers superior handling and performance on steep gradients. Constructed using the same carbon mold as the elite Dura-Ace model, these wheels are tubeless-ready, making them compatible with modern tire widths and enhancing both speed and aerodynamic efficiency.

The wheelset features cup-and-cone bearings with Borozon-treated races, significantly reducing friction for a smoother ride. These bearings are housed in a cold-forged, machined aluminum hub shell, designed with an increased flange width to improve lateral stiffness.

The rear hub incorporates a direct engagement mechanism with interlocking faces for near-instantaneous power transfer, giving you a competitive edge on race day.
