Derailleur Skipping On Cogs Sound

This is not an issue with the Neo itself, but rather a configuration problem.

Root Cause

There are a few things that can cause your chain to skip on your cogs. The first, and most frequent cause, is that the bike is not seated squarely on the dropouts. If the bike is skipping in all the gears and you’re using the QR skewer, this is a good bet, and worth checking out.

Dropout not sitting on the axle

It’s surprisingly easy to make this mistake. Even seasoned veterans will do it occasionally when in a hurry.

To prevent this from happening in the future, develop a technique for installing your bike on the Neo. Once the bike is on the trainer, but before you have tightened the skewer, press down on the seat with one hand, and with your other hand, lift the front wheel off the ground slightly. As soon as the front wheel loses contact with the ground, the bike should drop right into place, and then you can tighten the skewer.

Steps To Resolve

Loosen the skewer, press down on the seat with one hand, and lift the front wheel slightly off the ground with the other hand. As soon as the bike is perpendicular to the trainer axle, the bike should drop right into place. Retighten the skewer and you should be set.

  1. Do you have an article or video on indexing the rear derailleur on the Tacx Neo 2. With the constant resistance from the trainer it is difficult to turn the pedals by hand. The job of indexing would be much easier if you could turn off the resistance temporarily.
