I generally love the app, and hope someone knows of a fix for the below issue, as otherwise I’m going to have to retire from zwift, to prevent aggravating a knee issue that has already caused me to miss about 4 months of last year, which I need to avoid triggering again.
I use my Tacx Neo on zwift on an iPad mini over bluetooth, and I’ve noticed that when I ride at moderate speeds the speed of the ‘wheel’ and my virtual speed don’t match up (by the equivalent of about 4 sprockets), even on 100% realism. Basically I have to spin a much smaller gear, and have much less momentum than I would feel in real life. As an example, I checked some specific numbers this evening and realised that I was pushing around 85rpm in the 50x19/21 (i.e. around 27kph in the real world) to travel 40kph in zwift, so about a 1/3rd reduction in speed. This wouldn’t really be an issue (other than causing me to have to front shift/cross chain too often), except the virtual flywheel on the Neo also seems to reflect the ‘actual’ speed, so all of my riding on zwift is effectively a constant uphill slog without any momentum - even if I’m riding a flat route like the London Classic or Tempus Fugit. Because I have a knee issue, I really need to find a way of getting around this issue, or I’ll need to stop using zwift for training.
Is there a fix?
