Here are a few tips to get your resistance unit smoothed out:
1. Check resistance unit mounting bolt:
- If the mounting bolt has vibrated loose the resistance unit can move side to side, causing a vibration. Tighten the mounting bolt.
2. Check the L-bolt or roller tensioning knob:
- Be sure that the the spring is installed
- Check that roller tension is tight enough
3. Check your rear wheel:
- Often, it’s the condition of the rear wheel and/or rear tire that contributes to a vibration.
- Make sure tire is fully inflated – check the side of your tire for the manufacturer’s recommended inflation.
- Look for flat spots on the surface of the tire, check for wear. Replace if necessary.
- Make sure tire is properly seated on rim – make sure the tube is not bulging out of the tire.
- Make sure rear wheel is true and without hops – any hops in your rim will cause a vibration while you ride.
- Make sure there is no road debris on your tire.
4. Check the roller of the trainer:
- Look for flat or pitted spots – clean the roller with rubbing alcohol and a dry cloth – this will remove any rubber debris on the roller
- Make sure the bicycle is centered on the rear roller
- Make sure the bicycle is level within the trainer
- Make sure the trainer is level on the flooring
Also note: if the trainer has been dropped or the resistance unit has been impacted the shaft that runs inside the roller may be bent – rotate the flywheel by hand and watch to see if it is out of round. If so, a replacement resistance unit can be obtained through our crash replacement policy.
If after reviewing these trouble-shooting steps you are able to confirm that the trainer has not been impacted and you are still experiencing a vibration when riding please fill out a warranty claim form. {Add link here!}
