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