Elite Justo trainer

Hi all,

I am reactivating this topic.

I have the very same issue. What this ever resolved?

What I am experiencing is the following on my Justo 2.

-At the start of a workout in ERG mode I have to provide very high power before TR finds the target power. This lasts 30-40 seconds during which the cadence shows 0. This doesn’t happen all the times. I think if I try to start pedaling very early it is better.

-Every time I pause a workout (ERG mode) the same thing happens when I resume

-If I turn off ERG mode the cadence drops to 30-40 and stays like that.

-I confirm that on Elite My e-training app everything seems to work fine (for the limited testing have done)

I am in contact with Elite support who is telling me this is a TR issue.

I have opened a case with TR support and waiting for an answer.

Side note, I have tried a workout on Rouvy this morning and it seems to work smoothly. So shall I assume this is a TR issue?

I’m sorry that you are experiencing this same thing I was. Elite support SUCKS. And TR tried to be helpful, but in the end, they said they didn’t have time to look into it.

These two companies need to get their developers on a friggen call to resolve this. I recorded videos and set data files to them. STILL unresolved.

I was extremely frustrated. I basically put me Justo in the closet and went back to using my Tacx Neo 2T.

I just bought a Justo 2 thinking I was upgrading…

But for me this is worse because I cannot train if I turn ERG mode off. if I do the displayed cadence drops to 30-40 and so everything is messed up.

After investing in the Justo 2 I cannot afford to put in the closet and buy a new one.

I hope TR finds the time to address this or I would have to sadly give up on TR even if I paid for the full year.

On Rouvy it works flawlessly

You need to adjust the resistance in resistance mode. The default is 50% drop it to like 10 and see how it feels.

25

I think you misunderstood.

I am still pedaling at 85+ rpms

It’s the TR app the shows a fake 40 rpm

26

No, you edited your post.

Do you have a power meter on this bike?

27

yes I have assioma duo

28

Do they not report cadence to trainerroad? There should be a use for cadence option in the settings on the pier meter.

Do you have power match on?

29

I see…

I also have a cadence sensor bridged to the Justo 2.

I can use that as separate sensor I guess to display the value on TR.

Nevertheless if justo 2 has the wrong cadence, doesn’t that mess up all the power calculation?

to me that is the reason why all this happens.

I resume from a pause, TR reads cadence 0 so it thinks I am not pedaling and then the resistance skyrockets to match the target power…at least this is my naive assumption

Edit: thinking about it, it is worth trying to see what happens with external cadence sensor and erg mode…thanks for the tip

All the trainer can do is guess cadence, it doesn’t know your front gear it doesn’t know your back gear. It’s trying to interpret from pulses. The delay is because the trainer isn’t reporting it to TR because of that guessing.

Your pedals are moving at your actual cadence. I would say very few are relying on just the trainer for cadence.

Rouvy probably works because its relying on the pedals by default.

Since you have power meter pedals you should be using powermatch anyway so that your power source inside and out are the same.

With powermatch on the TR software just tells the trainer more or less resistance, the power value at the trainer itself is mostly irrelevant.

The only thing i can think of doing is to get more people to post complaints about this to get Nate’s attention. I’ve given them all the data. All they need to do is set up a meeting with the Elite developers and pinpoint the problem. I even offered to send my trainer to them for testing.

Did zwift take you up on this too? You’ve established this is a hardware/trainer problem not a software/trainerroad/zwift problem so what exactly are they supposed to do with it?

I noted it happened once to me, of it was even the same problem and never again.

I’d focus 100% of my effort on elite.

33

Few things that I don’t understand if the problem is the elite algorithm to determine cadence.

I have tried to use a dedicated cadence sensor bridged to the elite trainer. same behavior.

The cadence guessing can take up to 30-40 seconds? that seems a lot.

Why on the elite app everything works smoothly? the cadence calculation delay should be the same

34

I’m not sure exactly what it is, but the firmware update Elite did created the problem. So, I dont know if they inadvertently introduced a bug, or they fixed something and didn’t inform the s/w vendors of a potential issue that requires them to do an update to their s/w. I did not contact Zwift, even though the issue is present using their app.

In the meantime the shop where I bought it was so kind to offer a refurbished Justo 2 to try to see if this problem is on my specific unit.

I doubt it, but I will give it a shot and let you know.

Good test, but make sure you note the firmware version on each and upgrade to match to see if the problem persists.

Everything your describing is an issue with in elite sending out information. Why bridge the cadence to the trainer?

Just use cadence from your pedals, test that with power match on.

38

I can do that buT it defeats the idea of having a top of the line trainer which is supposed to have a power meter better then the assioma.

The other thing is that I have a second bike and I might have to switch pedals all the times.

But I will try for sure.

39

How is it better though? It’s not what you’re using outside, it’s measuring through drivetrain losses. It can only guess at cadence. It might be a fraction of a percent more accurate but that’s within margin of a error anyway.

I can’t think of a single trainer I’d consider better at measuring power than what’s at my feet.

It really doesnt matter because its all relative anyway.
