F4R WITH FFWD HUBS

Proven aerodynamics and an extremely lightweight are combined in the new F4R, making it the best choice for an all-round wheel set!

 

FFWD DARC technology is standard on the most aerodynamic FFWD models F9R and F6R. Adding this technology to the 45mm tubular rim makes the new F4R faster.

 

FFWD DARC:

DARC stands for ‘Double Arc’ which is the profile of the rim. It compresses air on the rim to create a faster airflow which reduces the drag behind the wheel.

 

FFWD Hubs:

The best hubs based on price and quality. High-end hubs with the least rolling resistance keep on going when you give them a spin.

TECHNOLOGY

Carbon

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...

Right out of the box, the presentation of the wheels impressed me! Read more
