From the instruction booklet of a Minoura turbo trainer :-
NOTE ON HIGH SPEED TRAINING
This magnetic resistance device may be able to realize you such an impossible situation as you can run at over 35 MPH speed easily because your tire doesn’t contact the earth, but only the rollers.
As you know, in fact, there is no way when you ride on the road, but you can do it on this Inter-Rim Ergo trainer with lowest resistance load force and high gear ratio.
And such a stupid high speed training may cause a problem on bearings and/or shaft.
This magnetic resistance device is designed for usual training under 35 MPH (56 KPH) speed, so you should keep your training speed under the limit.
If there is an awful noise or vibration from your magnetic resistance device during your training, please contact your purchased dealer or Minoura immediately.
I love it
- 'such a stupid high speed training...'
