Tacx Neo: No longer precisely synched with Zwift


My Neo and Zwift don’t seem to be accurately synched anymore. For example, when I have road feel on, the vibrations might last a second or two after returning to smooth pavement. Or when I stop riding and my avatar is pulled over to the side of the road, my flywheel continues to slowly spin for a little bit before stopping. I’d say this has started within the past month or so. Any ideas on if it’s a bug or how to fix it?


Have you tried updating the firmware on the trainer with the Tacx app? Is it on the latest version?

Interesting that you would say your issue has just started recently. I have had my Neo for more than 2 years and it has never been perfectly synched all the time. Some sections of the courses, usually on Watopia, are fine. Others at various times are out by a couple of seconds as you mention. Occasionally, I can miss an entire section of road feel.
I have not tried updating the firmware since it works well enough for me and sometimes updating causes more problems than it solves.

FWIW I have a separate issue on my neo with a huge time lag. it has been getting progressively worse, and today for the first time I felt a lag – and it was big, like 30s – with the gradient too. I admittedly haven’t updated my firmware, but I don’t think this is a Neo issue as my partner has a lag on his kicker.

interestingly, if I push out a lot of power, then stop say to tighten my shoe buckle and start peddling again, it sort of psychs out Zwift so my power never drops.

I agree that updating firmware can sometimes create new problems. In general - I don’t update firmware on anything until I have a problem. Y’alls are having problems that a firmware update to your respective trainers might just solve.

I’d totally respect your choice, but if I were in your shoes, I’d roll the dice on this risk/reward curve.
