The C:1 provides an upright, comfortable and confident rider position without sacrificing performance. A 10 speed (1×10) 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, Roll favor superior sealed bearings throughout for low maintenance and maximum lifespan. The components they use are anything but ‘standard’. You’ll feel a distinct difference in the ride, not because of one exceptional component but the considered combination of them all.
