A modern take on the Japanese Keirin track bicycle, the 6061 Track Series is the most advanced group of bicycles in our collection. Fast, lightweight, and designed for modern day fixed gear racing. We’ve built a bike that can dominate the velodrome and the streets. All models feature our custom-made track frame forged out of high-grade 6061 aluminum alloy, as well as a SRAM S-100 48-tooth crankset, and lightweight 43 mm deep-set rims. These bikes were born to win.
