19RCS BREMBO Radial Brake Master Cylinder, Folding Lever, 19mm 18 & 20 Ratio. Brembo 19RCS Brake Master Cylinder with folding lever, brake light switch and double banjo bolt. The brake lever itself is made up of two main components allowing for a fold up design, greatly reducing the risk of the lever snapping in the event of a crash (this is another patented system that only allows the lever to fold on impact, eliminating the possibility of the lever accidentally folding during use, a great safety feature).
