Just started to use Zwift with my tacx flux 2.Yesterday riding the round of Flanders I several times noticed that the slope increased to e.g. 11%, but the resistance just declined as well
as my speed. After let’s say 10 seconds the resistance came up. Could this be due to the rather weak wifi signal I have in my garage?
Check if you paired the trainer using the FE-C option. That is if you use ANT+
wifi should not have any influence except if you use the companion app as a bluetooth bridge.
Thx Gerry,
I use Zwift on my Ipad pro, so with BT.
Could it be that since I simultaneously connected my Garmin Edge 820 (with ANT+, on indoor mode) to the Tacx, this disturbs the signal somehow?
BTW, what do you mean by FE-C (is it just ANT+?)
Best, Ron
Yes the FE-C option is only applicable to ANT+
I paired the Tacx to the ipad with BT.
Do you think that additional connections (e.g. to the companion app and also to the Garmin Edge) may disturb the signal?
I would try to disconnect that but I dont think this is the issue. I would rather have a look at the firmware and check if you have the latest.
Not sure if it is the same problem, but with my CycelOps Magnus, it can’t handle slopes much over 9% with my weight of 190. This gets worse as its gets hot. If I am doing a hard climb and the grade goes over 10% the resistance will taper off after a period of time and decease until the grade comes down
I did try a few things: improved de wifi and switched off the ANT+ option in my flux 2, since I only use bluetooth. This did the job more or less.
One thing that is really annoying is that stil when I shift to a lower gear during a climb, my cadence (rpm) drops to 0 and stays there for up to 10 seconds. Speed is more or less retained, but nevertheless all riders pass by.
Any clue to fix this? firmware of my flux 2 is uptodate as is the zwift app.
thanks, Ron
I think this is because the trainer has a virtual cadence sensor, it measure the difference in power to calculate the cadence. The one fix I can think of is to get a separate cadence sensor. But cadence does not impact speed or power.
So if I would turn on the Ant+ and connect to the Garmin cadence sensor that is mounted on my bike, this should improve.
When starting Zwift, can I choose what cadence sensor should be used?
Yes in the paring screen.
thanks again Gerrie!
