Removing the rear wheel on an Aries can be done with a few tools, primarily a 15mm wrench and wire cutters (optional)
First, invert the bike (article with related information here: INVERTING BIKE FOR SERVICE ) and snip the zip tie closest to the rear axle -- while not required, it does allow for more movement of the cables:
Next, Rotate the NuVinci shifter so the Cable End Hardware is rotated towards the rear of the bike, and lift the metal lever to release the first cable from the black plastic part (known as the hub interface)
Unseat the cable housing from the Hub Interface:
Remove the other piece of cable end hardware from the Hub Interface:
Unseat the second cable housing from the Hub Interface, and move both cables clear of the rear wheel.
DO NOT MOVE THE SHIFTER WHEN THE CABLES ARE DISCONNECTED
Loosen both axle nuts with a wrench (15mm is ideal), remove them by turning counter-clockwise. Remove the black "no turn" washers. Set these parts aside for later.
Rotate the chain tensioner rearward while lifting the wheel out of the bike:
Re-installing the wheel requires that you pull the chain tensioner rearward again and get the chain on the cog while lowering it into position. Pay attention to the
brake disc as it slides into the brake caliper.
Rotate the Hub Interface so that it is even with the frame, and turn the axle so that the axle flats are perpendicular to the slots in the frame:
Slide the no turn washers onto each side of the axle, taking care to place the tab into the slot of the frame:
Screw both nuts on by hand, taking care to not "cross-thread" them. Once finger tight, use the wrench to securely tighten the nuts on both sides.
DOUBLE-CHECK THE NUTS TO BE SURE THEY ARE VERY TIGHT.
Re-install the first cable by placing the housing in the Hub Interface as shown, and inserting the small piece of cable end hardware in the pocket
closest to the small hole. Once in position, pull firmly on the other piece of cable end hardware to remove slack in the system.
In a similar fashion, seat the other cable housing, wrap the cable in the groove and replace the other cable end hardware by inserting it into the remaining pocket and flipping the lever down.
This requires pulling very firmly on the cable to get it into place.
Finally, install a new zip tie if you cut the original. Make sure the cable housing is clear of the chain:
Take the bike on a very short ride to test the rear brake, and to shift the NuVinci the full range to see if there are any issues. If there are, simply contact us at email@example.com, or call 877-991-7272 for advice.
Otherwise, enjoy riding!
