Find YOUR Brilliance.

The revolutionary Dimond Brilliant owned the fastest bike split on the Queen K in 2015, spurring the design renaissance that is taking the triathlon world by storm. The Brilliant showcases the Superfork, which flawlessly unites the front end of the bike with its elegant frame design. This drastically improves upon the aerodynamic and aesthetic qualities and allows for ease of access to the brakes via a secure, magnetic closure. With this gem as your whip, you will always be Brilliant Under Pressure. Available in four different paint schemes and almost any color imaginable, the Brilliant can be purchased as a frameset, stock build, or custom build. Please contact our Speed Consultants for a quote.

Dimond Brilliant Enve
We set the standard high with our Superfork. Enhanced aerodynamics and a clean front end complete the build. A magnetic closure ensures hassle-free access to service the brakes.
The Brilliant frame is hand crafted with rigorous attention to detail, materials and quality. A cultivated layup process provides a stiff, yet comfortable ride that allows you to stay aero for days.
Draw attention from check in, to transition, to the podium with customized paint. Our team will help you bring your ideas to life; after all, your bike is a reflection of you.
Choose from three builds or build this Brilliant frame up with custom parts to suit your specific needs.

I began riding the Dimond Premium Build in early July 2014, in preparation for IM Boulder and IM Hawaii. This bike is the smoothest riding, most stable tri bike I’ve ever ridden. It climbs and descends flawlessly and flies on the flats and rollers. I’m completely satisfied with this awesome American-made ride.

The frame set is the most significant difference. This design allows for a ride that is more comfortable than other designs without sacrificing any responsiveness. I believe it is also the fastest bike on the market. I am 100 percent satisfied and know that you will be as well.
