Handcrafted in Boulder, Colorado, the Mosaic RT-1 iTR is built around rider-specific geometry, fully integrated cable routing, and clearance for up to 35 mm tires. Constructed from Mosaic’s custom double-butted titanium tubing, every RT-1 is made to order based on the rider’s fit and intended use. For this build, the owner selected one of Mosaic’s Artist Series finishes, a collection of limited-edition paint layouts and custom designs that transform each frame into a one-of-a-kind build.
The build features SRAM RED AXS E1 with an integrated power meter. A custom Duke wheelset paired with 32 mm Challenge 4 Stagioni tires keeps the bike light, lively, and responsive, while components from Black Inc., Extralite, ENVE, and Form Cycling complete the build.
Every component was selected to suit the rider’s goals and complement the RT-1’s ride characteristics. The bike was assembled here at Above Category Cycling, where every detail was carefully considered from the initial consultation through the final build. With Mosaic’s current lead time sitting at 6 to 8 weeks, now is a great time to start planning your own custom build. If you’ve been considering a Mosaic or simply want to explore what’s possible, we’d be happy to help guide you through the process.
