I have an issue when riding on climb portal. I am using SIM mode set on my head unit. Direct mount trainer is a Dare2Ride and head unit with Wahoo Bolt. I am using Zwift on my android. My problem is when riding in red zone its a conplete grind and resistance seems to slip and then spin quickly but cannot keep steady cadence. I can pedal as normal in other gradients. I am connected via Bluetooth but an Ant+ option does not appear on connection page. Not sure if this is the issue and how can i find Ant option. Trainer difficulty makes no difference whether high or low.
What happens when you run the Dare2Ride app? Any firmware updates? I’m not sure if that app supports doing a test ride or calibration of the trainer but if it does, do that.
Maximum resistance scenarios are also a common time for a trainer to overheat, or reach its maximum resistance level which may be less than what you are trying to do.
Thanks Paul - haven’t even considered that but i will try. I have that app so should be straightforward to do any firmware updates. Has beem working fine in Erg mode and for most Zwift options. Problem only exists in Portal
