Re: Ironman Power compared to Stages Power

I have given up with the genius' power guesser. I am now always using an on-bike power meter. I don't know why tacx does not fix this as every test agrees that this is a problem with the genius. The vortex did a decent job despite the usual problems (with wrong power readings when the tyre is cold) ...

Re: Ironman Power compared to Stages Power

For everyone still not believing the Genius/Ironman measures power too high, they guys at bikeradar came to the same conclusion: http://www.bikeradar.com/road/gear/article/smart-trainers-the-best-options-weve-tested-and-what-to-consider-45980/?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed:...

Re: Ironman Power compared to Stages Power

Okay so might be I misunderstood this but I thought I read somewhere on the web that they would not continue this feature because of the lag you have with it. possibly a just a misinformation. but in general wouldn't you agree that a trainer that has a power meter (or at least gives power readings) ...

Re: Ironman Power compared to Stages Power

didn't I talk about current beta version? I have no access to an I-* device whatsoever, so no idea how it looks in ios. and as I said. it is absolutely not of interest if there may or may not be such option in Trainerroad. this is simply off topic.

Re: Ironman Power compared to Stages Power

That is confusing. You comment about using TrainerRoad but the power output of the trainer in is not well aligned with that of your powermeter, yet discourage use of the feature intended to eliminate the discrepancy by setting the trainers resistance based on your powermeter. If you have enabled th...

Re: Ironman Power compared to Stages Power

I don't use any TTS software. I just compare ant+ sensor data that should be correct without the need of any specific software. And I have firmware 3.25 which tacx gave to me after I had catastrophic power readings from the genius (with 3.17 installed). All I can say to you after having calibrated t...

Re: Ironman Power compared to Stages Power

okay seems I found a way to get the calibration done correctly. Ignore what the Tacx app says about calibration, it is simply not reliable. - put 8 bar on your trainer tyre - put your wheel in the trainer and tighten it nearly as much as possible (just so that the screw is not falling out yet) - war...

Re: Ironman Power compared to Stages Power

Hi! have the same problem with the genius smart. (which is the roughly the same as the ironman.) the stages is correct. I have a stages, a 4iiii, a vortex smart and a genius smart. stages, 4iiii and vortex more or less agree on power values. The genius overreads power. I have a support case open wit...

thanks for the link... interestingly the measuered values (app and bike computer) seem to don't differ more even when riding over the threshold.

Re: Anyone tried the Tacx Cycling app with PC Android Emulat

No but I am running it on a minix neo x7 android box connected to my 60" tv. that's a pretty good experience. the only drawback is that controlling the app without a touchscreen is a bit tricky, I am using a wireless usb keyboard with trackball for that, but e.g. klicking the plus and minus buttons ...

Re: Vortex Smart ANT+ Speed/Cadence sensor Wheel Diameter

Since Bushido and Genius motorbrakes can can produce higher levels of resistance than a Vortex or Vortex SMART, the idea is that training should require the same amount of energy expenditure regardless of the trainer, but during the effort on a Vortex/Vortex SMART, virtual speed will be will be imp...

Re: Vortex Smart ANT+ Speed/Cadence sensor Wheel Diameter

Sorry, you're on a Vortex Smart... overlooked that. You don't have a head unit. The normal Vortex has one. The Smart uses a tablet or smartphone and an app instead of the head unit. The Garmin cannot substitute the head unit. yeah... sorry about a confusion. I was talking about head unit as a more ...

Re: Vortex Smart ANT+ Speed/Cadence sensor Wheel Diameter

There is a wheel size setting in the head unit (the forerunner or edge what ever you like) ... for every speed sensor you can set a wheel size. If you connect a speed sensor it will be set to "automatic" but automatic determination of wheel size does not work wirth indoor trainers as I explained bef...

Re: Vortex Smart ANT+ Speed/Cadence sensor Wheel Diameter

okay... obviously noone is actually reading here what I am explaining. I am NOT USING THE GSC10. I am not using the same wheel size as on the road either. I use the ant+ signal of the vortex. you still need to know a "wheel size" parameter of the trainer (this sounds ridiculous as the trainer does n...

Re: Vortex Smart ANT+ Speed/Cadence sensor Wheel Diameter

try removing the Ant+ speed from your bike & then see if the Tacx app sends out the calculated speed to your watch..? I don't use the seperate sensor on my bike (although it is still present as I use THIS bike outdoors ocassionally too) (you can have n sensors paired in the FR920XT - which I have i...

Re: Vortex Smart ANT+ Speed/Cadence sensor Wheel Diameter

Im not 100% sure how Tacx is doing it right now with what ever version of software they have out, there could be a actual issue here or bug, but normally if your doing a RLV inside the app then the Ant+ speed is actually not needed as the smart trainers report your watts, which mean you can have a ...

Re: Vortex Smart ANT+ Speed/Cadence sensor Wheel Diameter

So this means the ant+ speed data from the trainer is actually useless without the tacx app as the app does some 'magic' to display a 'speed' and it will never match up the data delivered by the sensor... is it that what you are saying? This means there is no possibility for getting a 'correct' spee...

Re: Vortex Smart ANT+ Speed/Cadence sensor Wheel Diameter

I don't think this is what I am talking about. I am on 2.4.2 and the speed reported by the app is HIGHER than the speed reported by the Forerunner. Anyway the speed that is recorded by the app should be directly dependent to the speed the trainer ist spinning at. If you chose a wrong bike profile ju...

Vortex Smart ANT+ Speed/Cadence sensor Wheel Diameter

Hello! I newly own a Vortex Smart Trainer. This one has built in ANT+ and is able to report speed/cadence and power data to an ant+ receiver. Previously I have been using a Sirius and had speed/cadence reported from a garmin gsc10. Now when I use the trainer with the TACX cycling app it reports a di...
