I just tried my first GPX to workout converted ride. Once I got used to gearing and changes, everything was going great. Then I hit an odd issue. The first time the app hit a negative slope value, the bike (SB20) went crazy. I didn’t realize it was negative since the app displays rounded percent slope so it just showed 0% (I will be submitting a feature request to display decimal slope values). Resistance spiked and I couldn’t even pedal. I skipped the interval and continued. Everything was good until the next negative. - again displayed as 0%. I skipped and went on. The third time it happened I let it go and shifted to the easiest gearing to see how long it would last. Well it peaked over 600w and I had to skip after 30 seconds. Then it kept happening every few intervals - and not only on the negative slope ones. It even happened on a +4% slope. Finally at the end it was so erratic I had to end the workout. Here’s what the recording looks like:
Does TD not send negative slope correctly? Not that my bike (or any except the Neo I think) can mimic negative. But there’s still watts involved and I’d like to be able to pedal “downhill” for recovery intervals.
