member of your family have any medical devices that can be
affected by strong magnetic fields such as pacemakers or ICD’s.

o When moving the trainer, carry it by the threaded rods or the

Knobs.

o Do not close your hands between the leg and the frame.
o Before each use inspect the face of magnets for any metallic

debris. Wipe anything off with a rag.

Wheel Weight Use and Installation

The STAC Zero can usually be adjusted to achieve a good feel AND the
targeted resistance without use of the weights simply by spinning the
wheel faster. The wheel weight is included to improve the road feel of
the STAC Zero. They are optional to use.
