We designed and built this bike specifically to make the everyday ride far more than just an everyday ride. We began with our no compromise belief that every Roll bike should be effortlessly quick, forward thinking, and ultimately versatile. Custom geometry was essential to make the C:1 supremely comfortable, whilst swift and extremely agile. Our sculpted streamline frame and bespoke roll: custom riser bars, puts you in a more relaxed head and shoulder position, while still maintaining the most efficient pedal stroke. And whatever your journey, integrated mounting points allow a full complement of accessories and options.

The C:1 presented us with the challenge to create an upright, comfortable and confident rider position without sacrificing our performance ideals. A 10 speed (1x10) drivetrain with a single, sequential thumb shifter excels in this set up, for more intuitive shifting, and lower maintenance. The disc brakes on the C:1 provide consistent, assured braking 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. We'll custom build this bike specifically for you.
