As you can imagine, the 2015 Cyclocross Nationals brought all kinds of custom frame eye candy to town. Hidden in the fleets of Rock Lobsters and Stoempers are these blue “Singlebarrel” Mosaic XSS-1 singlespeed cross bikes. Built from True Temper tubing with Chris King, Shimano and ENVE rims, it’s not hard to spot one in the crowd of buzzing freewheels.

I bumped into Aaron from Mosaic and managed to get a few photos of his bike before the massive SSCX race took place yesterday. These bikes are lightweight, precision race machines and you can find out more about them by visiting Mosaic Cycles.
