The Roll-A-Click is a truly on-the-fly position adjustable lever, designed for OEM style master cylinders. The miniature "clicker" lever controls a roller cam assembly, giving riders the ability to manipulate lever position while riding. Brake fade and clutch adjustments can be tuned in with ease. Our CRG Roll-a-Click levers are the same as those used by all AMA factory Supersport and Superstock teams.
