We imagined it, we designed it, and we built it: all that we desired in a flat bar road bike crafted and engineered with superior components and uncompromised by convention or price. An iconic double diamond profile, deceptively fast, and deliberately understated. Ideal for those days when you want to sweat a little, or commute, or maybe both. The S:1 is designed with meticulous attention to detail. Ultimately to get you there discreetly, effortlessly, and very, very quickly.

With the S:1 we were determined to refine rider position to achieve superior control, handling, and comfort without sacrificing forward motion. Gender specific sports saddle, our custom roll: flat handlebar and cockpit set up combine to create the most effective and efficient position to transfer power into the pedals. There's a single thumb shifter for intuitive gear changing and a nifty 1x10 drive train that has the range of a traditional 2x9 but without the weight of a front derailleur. Our disc brakes offer performance far beyond traditional rim brakes, and although they're hidden, we favor superior sealed bearings throughout for low maintenance and maximum lifespan. The components we use are anything but 'standard'; We're committed to sourcing the best, and if we're not satisfied we design our own. You'll feel a distinct difference in the ride, not because of one exceptional component but the considered combination of them all. If you like to go faster farther, you'll fall in love with the S:1.
