FOUR PISTON TRANZBRAKE INSTALLED

Four Piston Tranzbrake

The J-Four Tranzbrake is the next generation of our original two piston design. The J-Four has the same Jaybrake quality with improved performance and lever feel. This brake is designed to mount to right side drive transmissions, replacing the need to clutter your rim with a rotor and caliper. The direct bolt on design allows for easy installation. The new J-Four design comes with an integrated progressively sized four piston caliper, 23 tooth sprocket and all needed stainless steel hardware. Requires: right side drive transmission, hydraulic hand or foot clutch (preferably Jaybrake’s), chain drive and 300 mm or smaller rear tire.
