All good things must come to an end, including 6002RS bearings.
This sound sits on the fence between normal and abnormal. It’s normal in the sense that eventually with heavy use, the bearing will wear out and will need to be replaced. It’s abnormal in terms of Neo noises. If your Neo sounds like this, you’ve got a problem that needs to be addressed.
Steps To Resolve
For The Faint Of Heart:
The easiest way to resolve this issue is to make a video showing that your Neo is having the same sort of low frequency humming that indicates a potential worn bearing. Attach that video in an email to email@example.com, and they will generally reply with further instructions, typically to replace the entire Neo disc.
Unfortunately, you will not be able to send only the Neo disc for replacement. You must make arrangements to have your entire Neo returned to Tacx to replace the disc. This is because variations in manufacture and individual magnet strength require that your Neo be recalibrated at the Tacx factory when the disc is replaced with a new one.
If you replace the disc then you actually need to recalibrate it [Neo]Hilko Schravenhoff, Tacx B.V.
Best if we receive it [Neo] and then we replace the disc and then recalibrate the machine
For US we are looking to support this within Garmin.
For The Real Hardcore:
We’ll have another article here shortly with step by step instructions soon, but meanwhile, here is a video by David Deady, explaining the process of examining the bearing, removing the bearing, and replacing the bearing.
