Brake Track Testing

When it comes to creating a rim that can handle brake heat, ENVE not only uses the latest aerospace high temperature resin and fiber systems, but we also rigorously test each wheel design on a state-of-the art test fixture designed in conjunction with The Utah Center for Aeronautical Innovation and aided by a grant from the State of Utah. The machine works by spinning a wheel using a chain and simulated rider load and then applying braking force while measuring temperature at multiple points hundreds of times a second using laser technology.
The machine can also precisely measure wheel and tire width and see how these dimensions change as braking is applied and heat is generated.

ENVE has tested all our rims as well other carbon rims on the market to create baselines of acceptable performance. From there we have set an internal standard for performance for each type and depth of rim.

Over the last year improving the performance and longevity of braking on the 100% carbon-braking surface of our road rims has been a priority for ENVE. Part of this effort has been to develop a new brake pad compound that will optimally manage heat, minimize abrasion, modulate, and perform in wet conditions with our rims.

While machine testing is essential for research and development, nothing can replace real-world testing. Fortunately, ENVE Composites is located near the steep Wasatch Mountain range. Our local lunch rides include the North Ogden Pass (2.6 miles, 1500ft. descent), and Powder Mountain Road (8 miles, 3500ft. descent).

Using the brake testing protocol in conjunction with our ride-testing program we have determined that the ENVE Grey brake pads, which were developed as a result of our testing, manage brake heat and rim degradation in addition to having better modulation than the other pads and compounds that we have tested.
