Wahoo trainers with Virtual Shifting Issue: "Free Watts" | October 2024

Hello. The issue of “sticky watts” or “ghost watts” is a well-known problem with many (I don’t know if all) Wahoo trainers. Despite attempts to fix it with the latest update, manual respin, reset, etc., Wahoo acknowledges that the issue is not resolved and “is still working on it”, without specifying a timeline or if they will succeed. This is particularly annoying at the start of descents, where both watts and RPMs fluctuate and take up to 25 seconds to drop to zero, preventing you from performing a supertuck enough time to get dropped from the group in races.

For this reason, I believe that Zwift could make a small modification to the requirements for performing a supertuck.

Right now, one of the requirements is to have watts below 11. Well, there would be at least two very simple solutions for Zwift to implement:

  1. Keep the 11 watts or, alternatively, require 0 RPM. This way, an external cadence sensor, which are very cheap, could be used, and the problem would be solved.

  2. Increase the maximum required power to 40 watts or similar (no one races at 40 watts) instead of the current 11.

I believe either of these options would solve this problem, at least temporarily, until Wahoo fixes this issue that has been bothering Wahoo users for a long time.

Regards, and I look forward to your opinions, proposals, or alternative solutions.
