Accossato Thumb Brake Master Cylinder

The Accossato Thumb Brake Master Cylinder is engineered in Italy for riders who need rear brake control while maintaining a firm grip on the handlebars. Operated with the left thumb, it provides an additional braking input that is particularly valuable in racing, where fine rear brake modulation improves corner entry stability and mid-corner balance. Built from CNC-machined aluminium and supplied with a long lever and bracket, this master cylinder is designed for strength, accuracy and rider ergonomics. Accossato thumb brakes are widely used in road racing and endurance competition, giving riders reliable control when foot operation is limited or less effective.
