Based on a cyclocross geometry, the ONLY ONE also features a wide fork crown and S-bend chainstays that can accommodate 700 X 38 tires, large chainrings, and narrow chain lines. “Want a road bike? Build it up with your favorite road group. Is light trail riding your thing? Do it cyclo-cross style. Prefer the simplicity of single speed or fixed gear? Bring it! Want a low maintenance city bike? Set it up with a belt drive and geared hub.”
