The hub-interface is stamped with angle reference number to assist in alignment figure The axle flats and the non-turn washer are used as a reference to correctly orient the hub-interface figure The non-turn washer will align with the opening of the dropout. The three common options for the dropouts are the horizontal dropout figure 25 , the rear-exit dropout figure 26 and the vertical dropout figure To install cable, it is easier to rotate the ratio-selector for better access.

Push the mechanism clockwise while pedaling slowly figure When the rear wheel is removed from the bike, it is necessary to remove the cables from the hub-interface. If the wheel is being removed for tire or tube service, or wheel truing, there is no need to remove the hub-interface or shift adapter washer.

If the intended service requires removing the hub-interface, begin by inspecting the interface at the rear dropout. If the hub-interface is correctly aligned, make note of the position of the non-turn washer as it points to the hub-interface markings.

The hub will accept a six-bolt rotor mount, a roller brake mount, or a simple cap for rim brakes. To change the hub configuration, begin by removing the left side locknut.

Hold axle in an axle vise and turn nut counter-clockwise figure There is a spacer washer under the locknut. If the wheel is intended for use with a rim brake, there is a simple plastic cover. Pop this cover up using only your hands figure There is no cone below this locknut.

The axle rides on cartridge bearings. There is no service beyond this point. If there is a problem with the hub or with the axle, it must be returned to the manufacturer for service figure The left side is fitted with threads in the hub shell for a lockring. This ring will hold the rotor mount and the roller brake mount secure to the hub shell. Fallbrook Technology supplies a proprietary pin tool to remove and secure this ring figure 53 and Another braking option is the roller brake fitting.

It will mate to the hub shell splines and is held in place with the same lockring as the rotor mount fitting figure Trade Resources.

Replacing Shift Cables Figure 2. Remove cable latch first Remove both cable fittings from the hub-interface figure 2. Loosen setscrew fittings on both cables. Pull cable ends free from the hub-interface. Use care not to lose setscrew fittings. Rotate the shifter so the bottom cover plate faces upward.

Shifter-handlebar setscrew is located under shifter. Use a small cross tip screwdriver to remove the shifter mechanism cover screw. Carefully pull up on plastic cover and remove figure 3. Figure 3. Remove Shifter Cover Figure 4. Use seal pick to left and remove cable end. Figure 5. Guide wire through shifter and out opposite side Figure 6. Push cable end into shifter seat. Route each shift cable through housing pieces and seat the housing ends into shifter barrel adjusters.

Zip-tie housing securely along frame and along chain or seat stay as desired. This will permit the housing to be removed and installed into the hub-interface. Figure 8. Check that the shift indicator shows the rider in the flat overdrive position. Measure the exposed wire between the cable ferrule and the 4mm diameter cable stop fitting for a distance of mm or between to mm figure 9. This can be an awkward to measurement to make accurately. One way to do this is to cut a piece of scrap housing to mm figure Slip the housing over the wire, and use a permanent marker to mark the wire.

Figure 9. Measure mm of exposed wire for underdrive cable Figure Secure shift cable fitting Figure Shift indicator showing underdrive mode Figure Measure and mark cable for placement of cable latch. No-turn washer and axle Figure Shift driver and hub-interface Figure Hub-interface that rotates the shift-driver. Seat stay routed option Figure Estimating the position on a forward facing dropout Figure Rear facing dropout. The shifting adapter, non-turn washers and axle nuts should be installed on axle.

Install chain over sprocket and engage axle into bike dropouts. Pull wheel fully into dropout. Rotate the axle using the non-turn washers so the washer tabs are pointed the dropout exit. Seat axle washers into dropouts and inspect hub-interface. When the wheel is mounted, inspect hub-interface. It must not contact or press against the frame or stay. Inspect for clearance between frame and hub-interface figure It may be necessary to rotate hub-interface to prevent contact. Look for clearance between hub-interface and frame If hub-interface is incorrectly aligned the wheel must be removed and the hub-interface reinstalled to a better alignment using a new combination of splines on the star ratchet and the shift driver.

DO NOT attempt to realign the hub-adapter by loosening the axle nuts, rotating the hub-interface, and retightening the axle nuts. Rotating the hub-interface on the driver without uninstalling it will change the available gear ratios. Secure axle nuts to to inch pounds torque Nm. Push ratio-selector to gain better access Install underdrive cable in the upper housing stop of the hub-interface. Pull on the underdrive cable to get as much slack as possible figure This will pull the overdrive cable into the housing.

Pull overdrive cable Figure Engage fitting into ratio-selector. Engage overdrive latch onto ratio-selector Figure Snap latch closed.

Full overdrive mode Figure Check play at underdrive cable. Underdrive mode Figure Check play at overdrive cable. It's the black box near the rear wheel. Once the cable is connected, a red light will turn on near the plug on the Harmony unit, you will still have to establish a connection from interface and "Harmony Desktop Software" by clicking black oval in the middle of the window. Make sure that the cord remains plugged in during the entire process.

The software will request you to choose a file to open-- it should be named something like "default. Select that file. Mini USB is pictured here "micro won't work : The port for the mini-USB is on the underside of the NuVinci controller, which is attached to the chain side of the rear wheel.

Once connected click the right of the three circles that is labeled "update firmware". A pop up window will announce whether it was successful and it will disrupt the connection. Establish the connection again by clicking on the oval in the middle of the software window.

Select the right of the 3 circles that is labeled "enviolo Automatic setup". Click " Send Settings to Harmony" , then Exit. Unplug the USB chord. Power on the bike and power on the Harmony system.

The display at this point will have some hash marks that are bouncing off each other indicating the system requires calibration. Press and hold the silver button on the NuVinci controller and hold for about 10 seconds-- the Orange lights on the display will start to cycle up and down, indicating that the unit is in calibration mode.
