A complete sprocket disc brake kit. This kit provides a clean open look, as a separate disc brake rotor is no longer needed. Each kit includes caliper, caliper bracket, disc rotor/sprocket and all hardware for installing it on your bike. The only parts missing are the master cylinder and brake line. A stock type rear master cylinder can be used but due to the design of this brake kit a master cylinder with adjusted plunger size is recommended and separately available. This kit is designed for a clean show bike look. Frame mounting bracket must be custom made. Kit contains 48-tooth sprocket. Available in a drilled or slotted design. Replacement sprockets, brake pads and master cylinder are separately available.
