Installing the Rotatable End Caps for the Tacx NEO 2T Trainer

NOTICE

The Tacx® Alpine is compatible with the Tacx NEO 2T trainer, but you must install the new, rotatable end caps on both sides of the trainer. The old end caps and spacer (for disk brakes) are not compatible. Using the old parts could lead to property damage.

If you have a Tacx NEO 3M trainer, see Installing the Tacx Alpine.

  1. Remove your bike from the Tacx NEO 2T trainer.
  2. Select an option:

    • If you have a quick release axle, use a 5 mm hex key to remove both end caps.

    • If you have a thru axle, use a 17 mm wrench to remove both end caps.

      NOTE: Some wrenches may not fit, and you may need to remove the cassette.
  3. Open installation kit B symbol, and take out the blue tool, spacer, and Driveside 5-6Nm locknut.
  4. Use the table to choose the correct parts for your axle type.
