The NEO is a silent trainer, but in some cases you might hear sound that comes from the trainer. We will try to explain what it is
Around 35 km an hour it is possible that you hear a whistle sound. This is air moving through the disc and could cause some resonance. This is normal behavior
Cracking sounds when cycling
This can easily be solved with a with little maintenance. Please see the maintenance page We advise you to grease the unit each year.
Also make sure that the cassette is tight enough. In many cases this is the problem. If you are unclear of the sound please contact Tacx with a short soundclip
Metal sound when moving the disc
There is always a possibility the metal or dirt comes between the disc. This is an open system and there are very strong magnets inside. If you hear a metal to metal sound in your disc, then this can be cleaned with the NEO extractor tool. Can be purchased here. More information can be found on the maintenance page,
