Full carbon clincher wheels with 45mm deep rims.
The FFWD Full Carbon Clincher wheels have been thoroughly tested in all areas of road cycling. With field-testing on different terrains and lab tests for brake performance, the FFWD FCC have proven to be strong and durable.
Both F2R FCC and F4R FCC are strong wheels that are technically able to handle riders over 100kg just like all our models. However not all terrains are suitable for every rider when it comes to Full Carbon Clincher wheels.
Depending on the combination of factors like rider weight, terrain and intensity the best suitable wheel set can be chosen.
We use 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. So, rather than use a stiffer, but more brittle carbon type, we chose durability over ultimate stiffness. In some lay-ups we add some higher modulus sheets to increase stiffness locally.
We actually use multiple layers of different types of carbon. Only the outer layer is made from a 3K weave. Underneath this layer are layers of UDF (Uni-Directional Fiber) sheets. A mixture of different angles to resemble a uniform material. Because carbon fiber can handle tension very well, we have to mix up the layers to make the rim stiff and strong enough. Pressure is not a great feature of a fiber. Just think of a string being pushed ). But when mixed correctly, the different angles interconnect through the resin to make it resistant to all kinds of forces . The 3K has a slightly lower stiffness/weight ratio than UDF (Uni-Directional Fiber) sheets of equal fibers, but it makes up by giving the rims a bombproof feature. Why? Because when a strand (or multiple) gets cut in UDF, by crashing for instance, the sheet is compromised and the tear will expand through a larger part of the sheet at continuous workload. A weave will stop the tear because it is intervened by the crossing layer of strands . Although it is not advised to ride with a 'hole' in your rims, situations can occur where you might not know of a damaged rim or it is not an option to stop right away. Then you have the extra safety of the 3K weave to get you home.
