The Shimano Dura-Ace WH-R9270-C36-TL is a pinnacle road front wheel built for riders who demand the perfect balance of light weight, aerodynamic efficiency, and all-conditions confidence. At 620g, its 36mm full-carbon D2-profile rim sits in the sweet spot of the Dura-Ace C-series — measurably faster than a shallow-section wheel, yet responsive and composed in crosswinds.

Highlights

  • 36mm deep full-carbon D2 aerodynamic rim profile
  • Tubeless-ready hooked-bead construction
  • 21mm internal / 28mm external rim width
  • 12×100mm thru-axle — tool-less internal cam skewer system
  • 24 straight-pull bladed stainless-steel spokes with external aluminium nipples
  • Centre Lock disc brake hub with CBN-coated bearing races
  • Optimised aerodynamically for 26–30mm tyre widths

Carbon Rim & Aerodynamics

The 36mm D2 rim profile is shaped to work with modern wider tyres, reducing turbulent airflow across the tyre-to-rim transition. An internal width of 21mm gives contemporary road tyres the ideal casing shape, while the hooked bead secures both tubeless and standard clincher tyres. The wide external profile (28mm) further smooths airflow without adding unnecessary rotational mass.

Hub & Bearing Technology

The Dura-Ace hub features CBN (Cubic Boron Nitride) coated cup-and-cone bearing races — the same precision-grinding technology found in Shimano's highest-spec bottom brackets. The Centre Lock disc interface makes rotor installation straightforward with a standard lockring tool. A tool-less thru-axle skewer uses an internal cam mechanism to deliver a secure, play-free fit that is significantly stiffer than a traditional quick-release axle.

Spoke System

Twenty-four straight-pull bladed stainless-steel spokes are laced in a symmetric 1:1 pattern. Bladed spokes reduce aerodynamic drag at moderate yaw angles and resist wind-induced rotation during tensioning, making wheel building and maintenance more predictable.

Compatibility & Fit

Designed for 700c road disc brake frames. Axle: 12×100mm front thru-axle. Brake: Centre Lock disc (rotor sold separately). Tyre compatibility: 25–32mm clincher or tubeless tyres with hooked bead. This is the front wheel only — the rear wheel (WH-R9270-C36-TL-R) is sold separately. Compatible with Shimano road disc brake systems across Dura-Ace R9200, Ultegra R8100, and other Shimano hydraulic road groupsets.

Shimano Dura-Ace wheels are backed by a 3-year warranty against defects in materials and workmanship from the date of purchase. This warranty does not cover normal wear items including bearings, spokes, tubeless tape, brake surfaces, or damage caused by misuse or improper installation. For warranty support, return the item to Tune Cycles.
