The crown jewel in the Dimond line up.

Countless hours of designing, testing, refining and searching for perfection has delivered the crown jewel in the Dimond line up, introducing – “The Marquise.” The Marquise offers two storage options for all your race day needs making this bike just as fast on race day as it is in the wind tunnel. This bike is offered with custom build and custom paint options at no extra charge. Marquise, separate yourself from the pack.

Superfork. 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.
Lunch Box. The Marquise frame offers 700 ml of internal storage, enough to keep all your race day nutrition hiding from the wind, but accessible when you need it.
The TOTES (tools or other technical equipment storage.) Perfectly sized for a flat kit so you never have to be worried about being stranded out on the race course, or on a long training ride.
Custom. The Marquise can be painted and built up to suit your needs. Our sales team can make this dream bike happen, the way you want it.

Lunch Box

Large enough to fit your whole lunch in. Almost three times the size of most storage systems, the Lunch Box has over 700ml of storage for all your favorite training and race day fuel.


(Tools Or Technical Equipment Storage) The TOTES was designed specifically for your flat kit and multitool storage. This new design improves aerodynamics and will totally save you for that unexpected flat during those long training or race days. Your significant other will be happy to hear they don’t have to pick you up anymore because you left your flat kit on your road bike. We got your back.

Disc Brakes

The stunning stiff-yet-comfortable frame offers the same integrated storage as the rim brake version. Implementing the 12mm thru-axle and flat-mount caliper standards, the Marquise Disc optimizes compatibility for use with several brake and wheel options.

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.

Bryan VanMeverenBrilliant Premium

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.
