Erratic spikes in power

Hello everyone,

Power spikes from the usual e.g. 100W up to 300W, every 30 seconds, and lasting 5 seconds a time, completely killing my workout session.

Has anyone else experienced this? Any solutions welcome!

Using Tacx, via Ant to MacBook, ERG mode. Been happily using this 3 times a week for the past year. All software and firmware up-to-date.


Probably best to email so they can dig in to the logs.
