Adjust the center frame position properly that the rear tire contacts both rollers.
If the tire touches the rear roller only and a clearance exists between the tire and the front
roller, the center frame repeats jumping while riding. Set the rear frame backward.
If the tire touches the front roller only, slippage occurs and it will bring premature tire wear.
Set the rear frame forward.
It's normal for the rear tire to sway or move back
and forth slightly when in use. As long as the tire
doesn't touch the sides of the rollers this is ok.
If you find the tire is not centered properly, loosen
the center frame locking knob and move the rear of
the trainer to center the tire, then tighten the knob
again securely.
