Explore the Koi

In the early 2000s a large and unique diamond gemstone was discovered in the Republic of Congo. Weighing well over 60 carats this humongous chunk of diamond filled with inclusions and color variations was slated for industrial use when a young diamond gemstone cutter saw something special and changed the fate of the diamond forever. This young gemologist had a vision of turning the diamond into the Koi Diamond. He cut the diamond in a pear shape, showing striations of white and orange with speckles of yellow and black. What is now a world famous 32 carat diamond gemstone symbolizing strength and perseverance was almost never created. 

In the quest to design the ultimate road bike the engineers and designers at Dimond created a few prototypes using their proprietary molding process. Most of these prototypes are then incorporated into the final design of a product. One particular prototype made it all the way to wind tunnel testing before eventually becoming what is now the Radiant. Another top performing prototype was recognized as being brilliant in its own right by a young Dimond engineer who was inspired by the story of the Koi gemstone.

“Due to their endurance and perseverance, the Koi are symbolic of overcoming adversity and fulfilling one’s destiny.”

 

This young engineer at Dimond presented a similar idea to save the prototype frame and refine it into a lower cost frameset. The Dimond Koi road bike was born in the USA and is now manufactured at our partner facilities in Asia to our exact specifications. This feature rich bike brings you a stunningly beautiful frameset at a lower cost that only Dimond can offer. With endurance and perseverance you can overcome adversity and fulfill your destiny with your own Dimond Koi Road Bike.
