Description of FFWD F9R Carbon Wheelset with DT Swiss 240s Hubs - Tubular - black/red/white
Fast Forward wheels are lightweight and durable. They convince with high manufacturing quality. The rims of the F9R wheels are handmade in the Netherlands of High-Tensile TC35 carbon. This gives the rims very high strength with sufficient stiffness.
The front wheel features 20 radial Sapim CX-Ray spokes and the rear wheel features 24 double crossed spokes to ensure optimum stiffness and a lossless power transmission. The DT Swiss 240s is the top-end hub for extremely lightweight wheelsets. The advantages of the 240s are their extremely low weight, their high-class contact free double flange seal system against water and dirt, their bearings made of stainless steel and a special coating wich guarantees for smooth rolling characteristics. Compatible with Shimano 9/10/11s or Campagnolo 9/10/11s cassettes.
The DARC technology stands for ‘Double Arc’ which refers to the profile of the rim. This will increase the pressure just like on the topside of an airfoil. Increased pressure results in a faster airflow and less resistance on the wheel which reduces the drag.
FFWD uses High-Tensile TC-35 carbon for the majority of the lay-up. This gives the rim a very high strength with sufficient stiffness to cope with hard application of the wheels. FFWD actually uses multiple layers of different types of carbon. Only the outer layer is made of a 3K weave. Underneath this layer are layers of UDF (Uni-Directional Fiber) sheets. A mixture of different angles to resemble a uniform material. The different angles interconnect through the resin to make the wheel resistant to all kinds of forces.
All rims are molded with a process FFWD calls ECOM (Equal Compression). This means that the rims are molded with a custom-made air bag that has the inner shape of the rim. This makes sure that the pressure/compression is equal on the entire inner surface of the rim. Result is a practically void less rim section and a smooth wall on the inside of the rim. Without voids, the carbon sheets are completely fused into one system. The rim structure is much better and you can make the rim lighter and stronger.
FFWD works closely with industry partners such as SwissStop for development and testing brake surfaces and brake pad compositions. The most rims are built differently and require different brake surface compositions. FFWD evaluated the best options for each type of wheel and found ways to further improve them. The result is the Confidence Brake Technology (CBT). Each CBT equipped wheel delivers vastly improved stopping power by 30% and provides the rider with consistent, reliable and responsive braking control in all conditions.
Please Note: Carbon rims can only be used with special brake pads. These are included in delivery.
This wheelset is for tubular tires that need to be glued onto the rim.
All FFWD wheels are handmade and tested by the manufacturer, thereby small traces can be caused to the surface.
