High Speed Vibration Sound

If any of the screws that hold the case against the frame of the Neo are loose, the resulting interaction between the case and the frame is audible.

Root Cause

There are dozens of screws that hold the Neo plastic shell case tightly to the Neo frame. If any of those screws become loosened, the plastic case has the freedom to vibrate against the frame of the Neo in that location. This will typically only occur within a certain range of disc speeds, where the frequency matches the natural frequency of the materials, and the vibration is strongest.

Steps To Resolve

  • Open your Tacx Training App on your mobile device, and set a negative slope of -5%
  • When the vibration begins, press around the Neo plastic with your hand until you locate the source of the vibration. With slight pressure, the noise should cease.
  • Tighten any loose screws in the area you identify as the source.

Additional Information

The screws that hold the case to the frame are type TORX T20. Please make sure you use the appropriate driver bit to prevent damage to the screw head.

TORX T20 bit

If you are using a torque wrench to tighten the screws, our testing revealed that 2Nm is the max limit you’ll want to set. This seats the screws firmly without risking damage to the female side of the casing.
