CBT: CONFIDENCE BRAKE TECHNOLOGY

At FFWD Wheels we are constantly working on improvement of our products. In this process of product deve- lopment we learned that the combination of compounds will make the difference between good or great. As techniques develop quickly it remains a continuous process at FFWD Wheels!

FFWD Wheels applies three different brake track layers depending on the type of rim or type of use.

CBT BBS
All FFWD tubular (road) rims have a Basalt brake surface (BBS). Reducing heat production and improving brake performance in combination with the supplied SwissStop black prince brake pads.

CBT 1.5
Based on 1.5k CARBON structure in combination with High TG Custom Compound Resin. Increasing braking power by 30% in all conditions, more durable and doesn’t make noise while braking.

CBT 3H
The F3R FCC has an exclusive brake surface. Mixing three different composites and a copper layer with a High TG Resin enables fast heat reduction and high brake efficiency. Durable and capable of higher tire pressure.

DARC

FFWD DARCTM technology is short for ‘Double Arc’ which refers to the profile of the rim. The revolutionary DARCTM profile improves aerodynamics dramatically by reducing the drag. Air has the characteristic to stick to its surface and by cre¬ating a negative arc section the air will be compressed more at the positive section. 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. The DARCTM profile is applied to all F4R, F6R and F9R models


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 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 [1]). But when mixed correctly, the different angles interconnect through the resin to make it resistant to all kinds of forces [2].
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 [3].

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.


warranty policy

We all have a breaking point. Of course our wheels are not indestructible. They’ll take any abuse that’ll make you go faster, not abuse in general. When something does go wrong though, know that you can rely on us to get you back up to speed as fast as possible.

Main Policy

FFWD warrants its products to be free from manufacturing defects for a period of two years after original date of purchase. This warranty only applies to the original owner and is not transferable. The seller is obliged to guarantee the item sold against latent defects which render it unsuitable for its intended usage, or reduce this usage to such an extent that the buyer would not have purchased the item, or that he would have purchased @it only at a lower price if he had known the latent defects existed.

 

Returning a FFWD wheel

Any return to FFWD for examination will be handled by the customer who will ensure that the product’s packaging is appropriate, that the product is insured, if necessary, and that the shipping costs are paid. Don’t forget to include the invoice with the wheel, as well as your name, address and phone number. IMPORTANT: If you want to return your wheel to FFWD, please make sure to return it without the tubular or clincher tire, without the sprockets and without the quick release skewer.

Warranty’s limitation

The FFWD warranty covers exclusively the manufacturing defects of its products and excludes, notably, from its scope of application any damage, prejudice and, more generally, any direct or indirect consequence which would result from bad use or failure to respect user instructions, the lack of maintenance or a non-conforming use of the product. The FFWD warranty does not cover parts that are subject to normal wear and tear. Wear and tear parts are subject to damage as a result of normal use and riding in conditions / usage for applications other than recommended. Wear and tear parts are identified as: • brake pads. • brake surface of tubular and clincher rims. • ball bearings IMPORTANT: Always use FFWD carbon brake pads when using FFWD full carbon wheels. Do not forget to change your carbon brake pads when you’re going to ride with wheels with a brake surface other than carbon. Debris from the brake surface might get stuck in the carbon brake pads which will result in unrepairable damage to your
