Re-commissioned the turbo trainer yesterday after a pretty dry summer and no real need to be indoors. All started up OK and had a few software updates (TTS 4) but when I started the training, target 100rpm, the trainer was showing over 200.
I didn't think much of that as it was about double the target and I thought it might be a software thing i.e. count each leg. But the weirdness continued when I dropped the cadence to 80, but the indicated value went up to 240.
Throughout this I was also using my Garmin Fenix 2, so I have a reasonable idea of the real cadence, plus the feel in my legs.
Anyone got any ideas or had a similar issue?
