  • Bicycle derailleur cable preload and sealing system
    Patent number: 5630338
    Abstract: A cable pre-load system and device attachable between a moveable control cable and a rigid frame for regulating tension in the control cable and sealing the control cable against contamination. The tensioning device includes a cable connector, a resilient tubular member with two ends and a frame connector. The cable connector attaches one end of the tubular member to the control cable to form a static seal about the control cable. The frame connector attaches the other end of the tubular member to the frame. The tubular member stretches between a first configuration and a second configuration in response to movement of the control cable to regulate tension in the control cable.
