Rim Construction

We source raw Toray T-700 carbon fiber fabric, impregnate it with resin using a 100% automated process to ensure the highest levels of quality control and raw material purity. It then takes shape in our proprietary design molds to ensure the highest quality finish.

Braking Surface

A proprietary high-heat resistant resin is utilized during rim construction for the braking surfaces that can withstand temperatures in excess of 200 degrees Celsius. This provides rapid heat dissipation and most importantly smooth and effective braking performance. The Brake pad is equally important in the braking process. That is why we provide specially design brake pads with our wheel set, or recommend replacement brake pads like Swiss Stop to insure proper usage, function and quality.

Internal Nipples

All KarbonSpeed rims features an internal alloy nipple design. Not only is the look super sexy, but internal nipple enhances aerodynamic efficiency by removing 44 exposed surface drag points from the aero profile.


The finished surface appearance is a beautiful matte black unidirectional carbon fiber layer. Laying up carbon fiber is as much black art as it is science - it's a skilled and acquired craft all done by hand. As such, each piece will have a slightly unique finished aesthetic. This is true whether we are talking about our XA&™ or KSr&™ Series Wheels, XR&™ Hydration Systems or KarbonKages&™. Precision-cut die decals are applied to the surface of the rim and then clear coated to ensure they are mated and bonded to the rim in the smoothest way possible.
