SHIMANO Dura Ace rear wheel 28" WH-R9270 C60 | thru axle
Shimano has also succeeded in further improving the optimum combination of stiffness, aerodynamics and low weight in the wheels of the 9200 Dura Ace generation. The individual components have been closely scrutinized and significantly optimized at critical points. This means you always have the best and fastest material on your bike.
The rim is made entirely of carbon, and it's not just the look on the scales that will make your heart beat faster - you can immediately convert your energy into propulsion when pedaling fast. Nothing is wasted. The new design reduces air resistance and thus enables higher speeds with less effort.
To improve puncture protection, you can convert to tubeless tires and increase riding comfort and grip thanks to the lower air pressures.
The slim hub features Shimano's own DIRECT ENGAGEMENT system, which significantly reduces idle travel and allows a very direct drive. The high bearing quality and perfect sealing ensure smooth running and a long service life. They are also adjustable and easy to maintain if necessary.
The new freehub body is made of aluminum and therefore also weighs considerably less without compromising stability or durability. However, it may only be fitted with the 12-speed Shimano Dura-Ace Road cassettes.
Thanks to the rim height of 60 mm, this rear wheel feels particularly at home when racing against the clock at high speeds.
