Wheel installation with Nexus hub

These instructions are written for a bicycle with a Nexus internally-geared rear hub.

To remove a rear wheel

To remove the rear wheel, you must first disconnect the shift and brake cables.

To disconnect the brake cable

Be careful not to touch the rear hub which may be hot from braking.

1. Press the cable carrier arm (Figure 1) forward, and the cable clamp bolt rearward, so the bolt aligns with the larger diameter hole in the carrier.

2. Pull the cable clamp bolt outward to disengage it from the carrier.

 3. Slide the brake cable stop forward to remove it from the brake arm.

 4. Undo brake strap bolt.

To disconnect the shift cable

1. Put the shifter in 1st gear.

 2. Pull the cable housing out of the shift cable housing stop.

 3. Rotate the shift cable fixing bolt until the washer flats align with the slit in the cog joint bracket.

4. Remove the cable.

To unbolt the axle from the frame

When loosening and tightening the axle nuts, do so gradually, in small increments, to prevent effecting the bearing hub adjustment.

1. Slightly loosen the axle nut on one side of the hub by about 1/4 turn.

2. Slightly loosen the axle nut on the other side of the hub about 1/4 turn.

3. Continue loosening the axle nuts in small increments until you can slide the hub from the dropouts.
