Shimano Dura Ace WH-R9200-C60-TU Wheelset - Tubular - QR - HG L2 | 12-speed

Dura Ace R9200 – Never Compromise

The Science of Speed. Speed was the mainspring in the development of this 12-speed road bike series of a new generation. Several years of research produced those innovations that make the Shimano Dura Ace R9200 even faster. Every component has been revised, refined and optimised to enable the decisive seconds of advantage – whether as a breakaway from the peloton or in the finish sprint on the Champs-Élysées.

The electronic Di2 parts rely on Wireless technology where it matters to make shifting even faster and more reliable. Smooth shifting is also the aim of the Hyperglide+ system, already known from the MTB segment, which is designed to bring out maximum performance and the full potential of every racer.

The wheels are a decisive pillar in Shimano's "Science of Speed" development concept, they literally bring the rider's performance to the road.

C60 rim profile – Lowest drag for maximum speed

The WH-R9200-C60 wheelset is the most aerodynamic version in the current Dura Ace portfolio, making it ideal for sprints and high-speed use. In addition, to enable a powerful response, the High Rigidity (HR) concept increases lateral stiffness by 20%, while from the ground up redesigned hubs not only reduce weight but also benefit the overall stiffness of the wheels.

The 60 mm high rim profile with its design for minimal air resistance underlines the suitability of the tubular tyre wheels for flat stages and time trials. The new wheel generation not only shines with reduced air resistance, but also offers technical refinements.

Thanks to Direct Engagement technology, the freewheel hubs offer outstanding drivetrain stiffness which results in an even more direct feeling of power transmission and is particularly noticeable in the starting torque. The stiffness of the entire wheel is also improved by the OPTBAL system which uses a 2:1 spoke ratio on the rear wheel.

OPTBAL

Wheels with the OPTBAL system use a 2:1 spoke ratio, resulting in twice as many spokes on the drivetrain side as on the opposite side. The technology counteracts the unbalanced tension caused by increasing cassette widths, especially on the right side. The OPTBAL construction balances out this spoke tension increasing the spokes' lifetime and improving the stiffness of the entire wheel as well.
