For Boulder, Colorado’s Mosaic Cycles, the Rouge Roubaix Builder Challenge was the perfect epilogue for the 2015 North American Handmade Bicycle Show. Many of the bikes featured at NAHBS found their way to the RRBC and rightfully so. Why build something if it’s not meant to be ridden… Into. The. Ground.

The Mosaic line is divided into a number of specific uses. There’s a binomial nomenclature of sorts, or a key, to deciphering what bike is made for what and out of what material. Each member from Team Mosaic chose a bike that best fit their riding style. Be it steel or titanium, disc or rim brake, each of these bikes were built specifically to reflect their own preference.

As for the application process and the overall team, Aaron selected Boulder shredmeister Brandon Newcomer on an RS-1 (road steel), Velo Magazine correspondent Spencer Powlison on an RS-1 and finally, Derek Yarra, the RRBC winner on an RT-1d (road titanium disc), which matches Aaron’s own bike selection.

Derek and Aaron’s bikes will fit a fat, plump tire and because titanium is a naturally forgiving material, they offered a bit of compliance during the 100 mile race. If you’d like a further break down on each of these riders and their bikes, head to Mosaic to read up.

… there’s more coming soon on what else Mosaic brought with them: a wild card group of ladies…

As for Derek’s RT-1d, it’s built with Shimano Ultegra Di2, R685 hydraulic road disc brakes, Shimano Pro Vibe cockpit, and Shimano RX80 tubeless-ready wheels. My personal favorite detail: the Shimano mtb pedals!

Team Mosaic would like to thank Shimano, q36.5 Kits and Rothera Caps.
