This is a rather uncommon sound, though we acknowledge that it is a problem. The source of the creaking is deceptively difficult to troubleshoot.
At this time, we cannot say conclusively what the root cause of the creaking is, as many different approaches have been successful. In some cases, it is clearly the two “shell” halves of the case slipping against each other. In other cases, it has been the leg hinges. In other cases, it has been the disc itself touching the inner plastic of the frame while the disc is in motion. In yet other more extreme cases of creaking and folding, Tacx has replaced the entire Neo.
Steps To Resolve The Problem
- Check the Neo to ensure there are no obvious loose screws on the plastic case. See the exploded diagram below for all of the screw locations.
- Check each hinge on the folding legs, and apply a light lubricant as needed.
- With your bike attached to the Neo, gently apply lateral pressure to see if you can determine where the movement is taking place. If it is taking place at the disc, you should contact Tacx support.
Not long ago, Shane Miller discovered the source of his 2016 Neo creaking was located behind the disc, requiring removal of the disc and application of lubricant within. As Shane correctly points out, this is not an approved method of addressing the problem, but it was effective for his particular case.
