  • Cable joining system for cycles
    Patent number: 6725978
    Abstract: An auxiliary braking system for supplementing an existing bicycle braking system is disclosed. The brake wire of the auxiliary braking system is removably secured to an existing primary brake wire, so that the actuation of the auxiliary braking system causes the main brake wire to pull and activate the caliper brakes. The interconnection of the auxiliary brake wire to the main brake wire is achieved through a housing joiner which secures the auxiliary brake wire to the top tube of the bicycle frame and a bullet clamp which creates a secure connection between the main brake wire and the auxiliary brake wire.
