INSTALLATION

NOTE: In order to use the Problem Solvers Rear Booster Kit, the rear wheel of your bicycle must be re-dished 3mm to the non-drive side. This can be accomplished by using the 6mm rear spacer on the non-drive side of your hub while in the truing stand and re-dishing to center. If you do not have the skills, experience and tools to re-dish your rear wheel, have this work done by a professional bicycle mechanic.

1. Remove the disc rotor from the rear wheel using a T25 Torx wrench.

2. Install disc rotor spacer between the hub shell and rotor using the included M5 x 15mm T25 bolts. Torque bolts to rotor manufacturer’s recommended torque value.

    WARNING: Do not use your original rotor bolts to mount the rotor and disc rotor spacer. Use only the M5 x 15mm bolts supplied with the Booster Hub Adapter.

3. Install the 142 to 148mm rear hub spacer with rear thru-axle on the non-driveside of hub.

4. Reinstall rear thru-axle according to manufacturer’s specifications.

   WARNING: A wheel attachment device that is not properly secured can allow the wheel to loosen or come off, suddenly stop the wheel, decrease your control, and cause you to fall.

ONGOING MAINTANENCE

Regularly inspect disc rotor bolts and thru-axle for tightness. Inspect your Rear  Booster Kit for signs of excessive wear, cracks, or other fatigue before every ride.
