Hi Nathan.
I’ve just found a post on the zwift forum from Dazzler about tacx flow smart trainers overheating during workouts with low cadence and watts over 250. Sharing in case useful:
Does this sound familiar? Hi. I’m sharing this because it’s taking me months to look in the right place for the problem, and someone may find it helpful.
For quite a while now, I’ve been experiencing bluetooth/power/resistance dropouts mid races/workouts. It normally happens when climbing or in longer races mostly. Lots of other people seem to be posting the same issue, and the discussion has centred on ANT/Bluetooth overload/proximity etc. I’ve tried all of the potential fixes over the past 18 months, but still get intermittent issues. It can go numerous times in one session and I have to wait, re-pair and hope it doesn’t happen again… before having to ditch the session in frustration. Sound familiar?
This week, halfway up Alpe Du Zwift, it happened BUT after re-pairing several times, and spitting a few swear words, a thought occurred - could the turbo unit itself be overheating? (I know I was.) I trained a fan on it - and didn’t get the problem again. All this time thinking it was a more technical issue. Here’s a forum on Garmin (only just found) that speaks of the same issues…
