Dimond Bikes

Some builds go beyond specs and paint.
Carl Clark recently took delivery of his dream road bike — a Dimond Radiant SL, built with SRAM RED 1x 12-speed wireless for simplicity, precision, and speed. Lightweight, brutally efficient, and purpose-driven.
What makes this one special is the detail that isn’t about performance numbers at all: Carl’s Green Beret insignia, integrated into the frame as a quiet nod to a lifetime of service and a standard that never fades.
“De Oppresso Liber.”
A reminder that the best builds tell a story — not just how fast you ride, but who you are.
Proud to build bikes that carry meaning, not just miles.

Five riders. Five sizes. Zero compromises.
This custom Christmas build included five Dimond Radiant SLs (46–56cm), each spec’d with: ✔️ SRAM AXS wireless shifting
✔️ 1x simplicity
✔️ 13-speed UDH compatibility
Modern road performance, scaled perfectly for every rider in the family.
That’s the power of custom.
That’s the Radiant SL.

Dimond Bikes were made to shine in the crosswinds of Kona! Every tube shape on the Dimond Ikon (pictured), Mogul, and Marquise are NACA airfoils optimized for low speed high yaw environments. Simply put, there is no faster triathlon bike. Just ask anyone who's owned a Dimond.

Are rim brake bikes dead? While demand for rim brake bikes has plummeted in the last 5 years, there are some customers still building amazing throw back machines like this gorgeous Marquise Rim Brake frame done in Alpenweiss White with Porsche Signal Yellow, Subaru WR Blue, and Audi Nardo Grey. Simple, clean, and elegant.
