The Shimano Ultegra WH-R8170-C60-TL is a 60mm deep-section carbon road wheel built for riders who demand genuine aerodynamic performance without sacrificing tubeless versatility or disc-brake compatibility. Engineered under Shimano's R8170 Ultegra platform, it brings race-proven technology to the committed road cyclist at a compelling price point.

Highlights

• 60mm carbon tubeless-ready rim for maximum aerodynamic advantage
• Shimano D2 rim profile optimised across 0–15° yaw angles to reduce drag in real-world crosswind conditions
• 21mm internal / 28mm external rim width suits modern tyre widths from 25–32mm
• 24 butted straight-pull aero spokes in a 2-cross pattern for stiffness and longevity
• Centre Lock disc brake mount — fast rotor installation via spline and lock ring
• 12×142mm thru-axle rear axle for improved rigidity and precise wheel retention
• Compatible with 11-speed and 12-speed Shimano HG road cassettes
• Tubeless-ready construction reduces rolling resistance and allows lower tyre pressures for improved grip

D2 Rim Profile & Aerodynamics

Shimano's D2 rim profile is the result of computational fluid dynamics and wind-tunnel testing. Unlike traditional aero rims optimised only for zero-yaw headwinds, the D2 shape balances drag reduction across a realistic range of yaw angles (0–15°), meaning it performs consistently during actual road riding where crosswinds are constant. The 60mm depth provides substantial aerodynamic benefit on flat and rolling terrain and time-trial efforts.

Tubeless-Ready Construction

The 21mm internal rim width is matched to Shimano's tubeless-compatible bead shelf, allowing the wheel to be set up with tubeless tyres straight out of the box (tubeless tyre and sealant required). Riders can also run standard clincher tyres with an inner tube. The wider profile supports tyre widths from 25mm to 32mm, optimising the tyre-to-rim air volume for comfort and traction.

Hub & Spoke System

The rear hub features anodised aluminium construction with a Shimano HG Spline L freehub body in steel, accommodating 11-speed and 12-speed road cassettes. The 24-spoke straight-pull butted aero spoke pattern (2.0–1.6–2.0mm) in a 2-cross lacing delivers an efficient, stiff wheel structure with aluminium nipples. The Centre Lock rotor mount accepts all Shimano Centre Lock disc rotors and uses a standard lock ring for quick, secure installation.
