Required tools

Steps

  1. Start by disassembling the derailleur mount as shown.

    Note: Older front derailleur mount version shown, but the mounting instructions are the same.

  2. Attach the derailleur mount to the frame as shown. You will want to leave the cable pulley post off for now until near the end. Also, if you are particular about the finish on your frame you will want to put something on the inside of the mount to protect the frame from getting scratched.
  3. Remove the chain guard from the right crank and install the second chain ring. The smaller chain ring should go on the inside. Put the chain back on the inside chain ring.

    Note: For those that want to keep the chain guard, you will need to get a longer set of chainring bolts and spacers.

  4. Remove the left grip from the handlebar. If you have an air compressor, then insert the tip of your blow gun under the grip and blow in some air. Doing so will break the seal between the grip and the bar slightly. Roll back the grip as far as you can and then blow in some more air. Continue this process until the grip is removed. If you do not have an air compressor, then a can of compressed air works just as well. If you have neither, then anything in an aerosol can will help, like WD-40.

    Install the grip shifter in the space vacated by the grip. You may want to loosen the front brake so you can adjust where it and the new shifter will sit. Install a new shifter grip or if you do not have one, cutting your old grip to 60 mm (or rougly 2 3/8") will work as well. Once everything is where you want it, attach the shifter to the bar by tightening the 2.5 mm hex screw on the underside of the shifter.

  5. Insert the shifter cable through your preferred cable housing. Your cable housing will need to be approximately 46" long. We zip-tied the new shifter cable to the other cables just in front of the cable holders along the top tube.
  6. The new cable should continue to run with the others, through the rear triangle. The cable should then be run out over the rear triangle as shown and inserted into the derailleur mount. We cut the existing zip-tie on the rear triangle and tied all three together.
  7. Insert the chain through the front derailleur and attach the derailleur to the mount. If your derailleur has two mounting holes, we used the bottom hole, but this may vary based on your particular derailleur. You will want to adjust the position of the derailleur mount so the chain is near the bottom third of the chain guide and near the inside of the guide.
  8. Attach the cable pulley to the derailleur mount, so the pulley is facing the frame. Make sure the shifter is in first gear. Guide the shifter cable under the pulley and attach it to the derailleur, removing any slack in the cable.
  9. Everything should now be in place to test the new derailleur. You may need to adjust the low and high stop screws on the derailleur, as well as fine tune the placement of the mount on the frame. This may take a little time, but patience is a virtue. Once the shifter is working you will want to cut the excess cable and attach a cable end. If using wire cutters and your cable frays when you cut it, just re twist the cable with your pliers.

    Take your Swift out for a ride to test your new setup. You may want to take along your screw driver and 4 mm allen wrench just in case you want to make any further adjustments.
