I'm Noticing Vibration From My Trainer's Resistance Unit. What Should I Do?

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.
