Ride Quality

Climbing the French Alps or crushing the rough roads of Tucson, our unique beam design perfectly combines efficiency and comfort to get you home faster and allow you to stay in the aero position.


We offer custom builds and paint for the Brilliant line. If you don’t see exactly what you need in one of our builds, contact us and we can set it up the way you want.


Every Dimond starts as individual plies of carbon fiber. Through an intensive and meticulous process, the carbon fiber is molded into the beam frame, sanded to perfection and painted with acute attention to detail.
