  • Replacing Shifting Cables

    To replace the shifting cables, normal 1.1 mm ones are required as shown in the video.

  • Resetting the Hub to Full Overdrive

    If the spline nut and shift driver marks are not aligned, then resetting the hub to full overdrive is needed, as shown below.

  • Resolve Stuck CVP

    When resolving stuck CVP, make sure you are not damaging the shift driver, as it will make it impossible to mount the hub interface. For hubs stuck in a high gear, the shift driver needs to be rotated clockwise, and for low geared stuck hubs, the rotation is counterclockwise.

    Afterward, for Nfinity™ products, reset the hub to full overdrive, and for Harmony™ systems, do a re-calibration.
