Hi,

Yeah, so using ANT+ with your P1 pedals will be more reliable power data as it totals the left and right pedals power and TR receives it. Over Bluetooth, it'll pair but only double the readings of one of the pedals which could lead to less-reliable power data. Both ways work, but you'll get a more accurate power reading over ANT+.

With that difference you're seeing, we actually have built into the app a feature known as PowerMatch to solve this problem. Instead of adjusting your FTP to account for the difference, you can implement PowerMatch which takes care of it for you. With PowerMatch enabled, we'll take the readings from your power meter and offset any difference in your pm's readings and your kickr's readings to make sure your kickr is adjusting resistance based on the power from your power meter.

You can learn more about PowerMatch here: PowerMatch explained

Feel free to let us know if you run into any other questions or concerns at support@trainerroad.com.

Thanks!

Interesting. Yeah, would you mind sending this over to our support department at support@trainerroad.com when you get a sec? We'll be able to keep better track of our conversation over there. :) Also include whether or not you're using a dedicated cadence sensor, cadence supplied from a power meter, or the cadence that is supplied by the Kickr (if connected as an ANT+ FE-C trainer).

Thank you — talk to you soon!

Nick,

I'm enjoying my the start to my winter with SSB Low Vol 1 and making great progress.

I am thinking of how to log my outdoor rides for the power and TSS this spring. My phone has ant+. Can I just select one of the "free" rides under workouts and ride? Call it a TSS filler outside of whatever plan I'm riding at the time?

Thanks.

How far to dial back? I have done sweet spot base 1& 2. I am now on week 3 of Olympic build. I now have a wisdom tooth infection 🙄Which has floored me. Time off unknown but it's obviously Christmas next week. When I start back, should I retest or dial back 10%. Which the commentary suggests to do if struggling but I never have had to. Suggestions welcome

Many of the original version kickr's have an inaccuracy issue and overstate power
By 25-30w

I'm observing the following issue with powermatch (TR 1.0.0.20215 on MAC, Garmin Vector 2, Tacx Vortex Smart, all using ANT+) where its taking awhile for TR to increase the resistance to target level on first interval but then some what ok on subsequent intervals. Have tried with smoothing on and off, thou is better with smoothing on of 5 seconds.

Hi,

I was just wondering if you guys have an update on when support for native Bluetooth chips might be implemented for the Windows Desktop app? I seem to recall it being mentioned (possibly on one of the podcasts) that it was imminent?

I managed to break my ANT+ dongle recently and was wondering whether to buy a new one, or hold out for this and just carrying on using it on my phone for now.

Many thanks!

+1 for this. Should I submit a ticket?

+2!

I removed the ant+ USB dongle and put it back in again. After that, the KICKR immediately reacted like it should. After that, this didn't happen again. Maybe that'll work for now for you as well?

Glad to hear it!

There shouldn't be any issue in using the free rides to calculate your TSS like that — good thinking. Of course there is always the option to use a dedicated 'head-unit' as well. Either will get the job done. :)

Cheers,

Any plans to have TR run on a Chromebook? If so, what's the timing?

We're still planning on making this happen, but we're not quite there yet. I would assume we're not too far out though if there was chatter on a recent episode, but I don't have a definitive ETA. Using your phone should get the job done in the meantime. :)

Happy Training!

You're hitting what's known as a "wattage floor" or "resistance floor" of the trainer given the gearing ratio you're in that causes a weird transition.Try switching into an easier gear to match your power to the target during your recovery intervals and you should have a smoother transition into your intervals.

Our algorithm keeps a running offset of the difference between your current actual power and the target power. This offset helps us tell your trainer to adjust to keep you as close as possible to the target power. However, when you hut the wattage floor and your trainer cannot go any lower, this offset falsely continues to grow larger. Then, when you hit your next interval, you have an inflated offset. the offset shrinks every second, which is why it looks like your trainer is just slowly increasing resisatnce until it finally hit the target and performs better.

Let us know if this gives you some better results — thanks!

Check out my reply to viperlogic, it should help you as well. If getting into an easy gearing ratio and matching your power to the recovery interval doesn't help in the transition into the following interval, shoot us an email and we'll take a look.

Thanks!

Take a look at my reply to viperlogic when you get a chance — it'll explain things more in-depth. Try easing into an easier gearing ratio to make sure you match your power to the target during recovery intervals. This will help in the smooth transition into the next interval.

Let us know if this helps!

At the moment, it depends on the Chromebook. We don't officially support it, though the earlier models that support native android apps will operate TR. Not native BTLE though.

We'll update everyone as we learn more, but at the moment we don't have an ETA.

Thanks Jim!

Hi Nick, thanks for the response. How is it that subsequent intervals don't have the same "issue"? Regards your recommendation of changing gear ratios, should one do this just before interval or at start of the interval?

Nick, I am seeing a similar issue for me when using powermatch with my Quarq and Magnus trainer. However, I am seeing this issue right at the beginning of a workout. TrainerRoad doesn't seem to be adjusting the resistance correctly at the beginning, which makes me about 20w below the target power. It usually takes 1 to 2 minutes before the resistance will match the target power. After that, power match it seems to work just fine. Although during VO2 max intervals sometimes the resistance increases so much that I can barely turn the pedals because my cadence slows down.

Same issue here with Computrainer. Mine usually takes about 20 seconds to fix itself, right at the beginning of the workout (during warm up) and then no issues after that. This isn't really an issue for me since it's happened several times and I know it'll fix itself. I honestly thought it might be an issue with ERG Mode on the Computrainer I was using, but switched to another Computrainer and had the same issue.
Edit: This hasn't happened in the last 3 workouts.

Things looking better since changing gears before and after interval...

Is this trick (can you describe what exactly you do?) also applicable in ERG mode with auto Power Match?
I did not have a chance to use other smart turbo trainer than Real Turbo Muin, so still do not know whether pretty slow power adjustment is the domain of this trainer or the controlling app.
Sometimes it takes 1min or so to reach target power. If you have longer ish intervals, that is not a big deal. But with the shorter ones, sometimes it is not workable using ERG mode.

That's more like what we're looking for. :) I don't really have an explanation for why the transition was smoother in one interval versus the other in that previous screenshot, though. I've brought it up with one of our support development specialists to see if we can make some sense of it. I'll keep you in the loop.

For your question on whether you need to switch gears before intervals or at start of the interval: How you're approaching it now looks to be working well for you, but the main goal to alleviate the issue I described is to simply just make sure you're matching your power to the recovery interval. So how you accomplish that shouldn't really matter as long as your gearing lets you hit those targets. That'll keep that false offset from growing which would otherwise prevent your trainer from increasing resistance quick enough to hit the target power of your high-intensity intervals.

It's likely that you could actually stay in whatever gearing ratio that helps you hit your target power during those recovery intervals because your trainer should have no problem increasing the resistance in that transition from recovery interval into high-intensity interval if that false offset doesn't grow from you not hitting that target.

Trying to dial this in myself has been different depending on the trainer/power meter combo, but switching into an easier gear after a high-intensity interval to transition into the recovery interval has worked well. Then I just leave it there. Then if there's a really large jump in power, transitioning into a harder gear as I move out of the recovery interval and into the high-intensity interval has helped (if you're experiencing lag in a situation like that).

Let me know if any of that is unclear. :)

I believe this is PowerMatch getting its footing so-to-speak. I've heard users eliminate the length of time it takes to match target power by switching gearing around as well, but this is separate from what I was describing to 'viperlogic' above. And with the sudden increase in resistance in those VO2max intervals, it'll help to anticipate that increase by speeding up your cadence and preparing yourself for the increase in power when you hear the 3 beeps before your next interval begins. :)

We've decided to dedicate some development resources to evaluating PowerMatch and ways we can improve upon it in the future. We'll keep everyone in the loop with progress there. Let us know at support@trainerroad.com if you run into anymore issues.

Cheers,

I was thinking this may be PowerMatch gaining its footing and trying to establish the correct offset given both devices not being used since their prior engagement, but I'm not sure since you've been A-okay your last few workouts. Anything noticeable in your training environment that may have changed? Or have you been starting your workout in a different gearing ratio perhaps?

Thanks,

That's actually the context we're chatting about it in (ERG + PowerMatch). ;)

I just found your profile and was taking a look at some of your recent workouts to get an idea of what you're experiencing. Though I'm not entirely convinced everything is paired up correctly. Would you mind sending us an email at support@trainerroad.com along with a screenshot of your devices tab in the app and brief description of what you're experiencing to make sure we're all good on that front? If all is well there we can then proceed with the recommendation to help in smooth transitions from interval-to-interval.

You can let them know we spoke on the forums and we just want to confirm everything is paired properly to make sure your training experience is the best it can be.

Thanks Chris!
