Shimano Ultegra R8170 C60 Tubeless CL Disc Front Wheel

Shimano Ultegra R8170 C60 Tubeless CL Disc Front Wheel

Born from the quest for unrivalled speed, the Shimano Ultegra R8170 C60 Tubeless CL Disc Front Wheel delivers supreme aerodynamic performance for situations where pace is key. The tubeless-ready rim profile is the same as that found on the highest-end Dura-Ace equivalent and features a contemporary 21mm internal profile to suit modern tyre widths. The tall 60mm depth is ideal for sprinters and TT riders seeking minimal air resistance, with its high levels of rigidity offering a stable platform.

Hidden within the hub is an ultra low-friction cup and cone bearing system, which utilises Borozon treated bearing surfaces to keep drag to an absolute minimum. The Labyrinth double-contact sealing reduces water ingress to fight corrosion, making for a durable hub that is designed to stand seasons of use. Wide flange spacing boosts lateral stiffness and bladed straight-pull spokes balance compliance and rigidity to provide a smooth ride.
