Shimano WH-RS81 C50 Carbon Clincher Wheel 50 mm 9/10/11-speed Rear
Shimano have a long and illustrious history of producing reliable, state of the art components and it is no different when it comes to the Shimano WH-RS81 C50 Carbon Clincher Wheel 50 mm 9/10/11-speed Rear. A race ready rear wheel, the WH-RS81 C50 is made up of a carbon and alloy clincher rim, which balances strength, stiffness and weight perfectly and ultimately results in a true high performance wheel.
The alloy rim works with standard brake pads and offers assured braking, whatever the weather.
Cutting through the wind, the 50 millimetre deep rim is 22.4 millimetres wide. This means it is incredibly aerodynamic as well as stable, whether you push it hard in a sprint or bank it over through a corner.
A durable option, the wheel features 21 stainless steel butted and bladed straight pull spokes. This adds to the WH-RS81's balanced and stiff credentials.
Stiffness is further enhanced by the flange being widely spaced. Shimano components are renowned for being tough and the labyrinth double contact sealing on the hub acts have been added to stop water penetration, mud and other grime from effecting the hub's smooth rolling performance.
The polished bearing races also reduce friction and the click bearing, digital adjustment means looking after this wheel need not be a headache.
Cold forged, the hub shell has been constructed out of machined aluminium and houses an oversized 7075 alloy axle. This contributes to the wheel's impressive 1067 gram weight.
Compatible with a range of Shimano cassettes, including 8, 9, 10 and 11-speed variants and being a clincher rim means this wheel is a versatile option for road, cyclocross, time trials and triathlons.
