Shimano Ultegra R8170 C50 Tubeless CL Disc Rear Wheel

Shimano Ultegra R8170 C50 Tubeless CL Disc Rear Wheel

Designed to deliver lightweight performance and premium stiffness, the Shimano Ultegra R8170 C50 Tubeless CL Disc Rear Wheel is ideal for fast-paced race use. Utilising the same rim profile as the lauded Dura-Ace model, the rim features a modern 21mm internal diameter that pairs well with a wide range of tyres. The 50mm height is fast and aerodynamic and performs across an array of gradients, with its increased rigidity offering sublime efficiency.

The rapid engagement hub delivers instantaneous acceleration for punchy sprints and features wide flange spacing to boost lateral stiffness. Labyrinth double-contact seals prevent water ingress for a lasting smooth feel, and the bladed straight-pull spokes blend rigidity and aerodynamics for enhanced performance.
