PowerMatch Experiences

Hi Chad, we have the version info in the ride log, which Support have access to, but, in this atypical case, we are missing the output from the PowerMatch feature, which would be telling us what version it is. That is a problem in itself that we will need to look at.

Nice. Not surprising you guys already had that covered :wink:

Is there anyway, after the fact, that I can tell if it was done in legacy or new from my side?

No, unfortunately not. This is a strange case of the log file missing some information. Otherwise, we’d be able to easily say which version you were on.

Awesome insight! Thank you Alhan :slight_smile: … for what it’s worth, I did a couple of easy 1-hr rides this week (“Recess”), SRM+Kickr (both via Ant+), w/ the new powermatch (and not legacy) and it performed very well. That said, there aren’t any changes in power demand / intervals on such a ride. But, then again, the warm-up where I experienced the fluke w/ my first shot w/ the new version was the same level power demand as “recess.” I will give the new version another solid extended attempt next week and report back! Thanks again, --kellen

wonder if pushing a big gear (54t w 14t cog) and low power (160) could result in high flywheel speed, with very low relative resistance… mimicking more extreme power flux like when riding on rollers?? …I will see what happens at longer SS and Threshold pwr with the new PM version. Knowing that you all are so on-top of making sure this is going to be a great experience for everyone makes experimenting, testing, and reporting back fun and interesting. Much appreciated. --kellen

I am riding indoors for the first time in awhile, and have the latest version of TR on my Windows PC. I have a Quarq PM and a Kickr Snap. I use Standard mode, not ERG, for my workouts, but I switched to use the new PowerMatch even though:

Power Match only ever applies when using ERG mode. At any point when in Resistance or Standard mode (manually selected or workout swapped), the trainer power data is ignored.

What I’ve noticed in my workouts the last two days is that suddenly the resistance seems to be much higher than it used to be. I’m not sure if this is related to powermatch or if there’s something else, but I normally would be riding more in the middle of my cogs for the types of workouts I did yesterday and today, but I found myself using my biggest (easiest) cogs and small chainring. I should have tried out today’s workout with the legacy powermatch for comparison, but I was kind of rushed when I was setting up and just forgot about it until I was partway through, and I didn’t think I could change after already starting the workout. (Maybe that’s wrong?) Anyway, I get the feeling most people use ERG, not Standard mode, but this was what I was finding. More experimenting necessary, but just thought I’d check here to see anyone had other suggestions I should try besides just the powermatch setting.

  • Check the “Standard” mode setting you have in use.

    • This is visible at the bottom, and roughly left side of the screen, right next to the [Standard] mode setting control.
    • It will be a number from 1-9 for Standard mode.
  • It’s entirely possible that your new TR install defaulted to a setting that is different than what you had set for your prior TR install.

    • Ex: If you previously had it set at to something like 1 or 2, and the new install defaulted to something like 3 or 4, it will feel harder, which would lead to needing to use lower gearing (larger rear cogs) to hit the same power.

Thanks, that’s a good point, but I was on the same level in Standard that I had been before. I didn’t decrease it further, although I could have. So that’s why I was jumping to the PowerMatch change because I couldn’t figure out what else was different.

Might be worth an email to support@trainerroad.com then.

I have no reason to believe that PowerMatch setting would affect Standard mode in any way, but maybe there are some gremlins hiding in there?

Like you the smoke and air quality drove me inside yesterday. I tried using Wahoo app to set Standard/Level mode, and tried Resistance too, for a 4 sets of 4x15-sec sprint workout. Oddly enough the Kickr direct-drive felt too easy, even at Level 9. Weird. I’ve never been a fan of the Wahoo app but wanted to try it again, so I could recall why I prefer TrainerRoad. I’ll likely be doing the same as you this weekend, and will let you know how it goes with Standard mode (setup a bit different: TrainerRoad on MacBook Pro, Stages LR PM, Kickr 2017 direct-drive).

@mcneese.chad I’m going try a couple more things before contacting support, but I may end up there eventually.

@bbarrera as I look outside and see smoke between the trees (and a water-drop helicopter just flew over the house), I have the feeling I’m going to be indoors for at least another couple of days. Interesting experience that you had with the Wahoo app–I haven’t really tried their app much. I’ll be interested in what you find with TR and your setup.

we had a little relief this morning, but the forecast is ominous:

so I might be not doing any cycling for awhile, based on similar conditions during the Camp Fire two years ago…

@alhan
I did my first ride with the new PowerMatch in the beta iOS app. I just wanted to say that so far the results are great vs the old powermatch. I’m using a kickr snap (my unit is particularly bad at both power accuracy and precision by itself - without power match), and a Specialized left crank power meter.

Improvements I noticed:

  • Holds a constant power better
  • Responds to step down in power much better - even with or without cadence changes. With old powermatch, when the power stepped down after a hard interval, I used to have to grab the brakes to slow down the wheel to my lower resting cadence, otherwise it would just freewheel at zero power for a long time. The new power match keeps right on the power and I can naturally bring my cadence down
  • With the old powermatch, if I stopped pedaling, it would really struggle with hitting the power target for about a minute after I resumed. This is gone

I have been using power match on Android mobile with my Favero UNO pedals and Bkool Smart Pro 2.

A quick comparison in terms of power numbers indicated the pedals were always 20-30w lower than my trainer.

When using powermatch the results were fairly erratic but manageable for my plans. However when running a ramp test with power match on my mobile it was pretty hard going as the steps up would swing atleast 20w higher than target before settling out. (pic 1)


I completed another ramp test yesterday but this time used TrainerRoad iOS on my Mac and selected the new powermatch. (pic 2). It was very smooth but I am now questioning if powermatch was even being used. I definitely had it enabled, on Auto, ERG trainer mode.

Main reasons for questioning it are.

  1. All previous mobile app training sessions have registered the favero pedals as the power source. The most recent ramp test on Macbook iOS referenced the trainer
  2. The power was so smooth it seems to good to be powermatch?
  3. My FTP went from 230w to 254w which is roughly the 20-30w difference i have previously observed when comparing the pedals to the trainer.

My last 2 tests came in at 230w so maybe I am stronger after SSB MV1 & MV2 but kinda feel like i’ve just changed the measuring tape.

Normally, seeing that second test I’d say you were not using a pedal based power meter; it’s not spikey enough. However, having used the new power match myself for a few rides I am seeing the same as you. It’s not a smooth as trainer only, no power match, but is a lot less spikey than previously power matching from pedals.

Wow that looks awesome. I tried powermatch last year but switched to erg as I felt the technology wasn’t quite there yet.

I’m going to give the new powermatch a shot today with my vo2 workout, will report back.

I am using the assioma duo and the new powermatch actually gave less spike results but not as smooth as your second ramp test. You should experiment with the sensitivity level. I set mine at a lower level of 0.3 because I aim to keep my cadence steady so I do not want the powermatch to over react if there are slight variation in my cadence.

tacx neo 2t, assioma duo pedals. power match was not great. I found way too much variability and lag during changes. No I use Garmin to track workout independent of TR and have my Garmin head unit linked to assioma pedals and TR linked to tacx. At most the difference is 1-2 watts (FTP ~200) for NP, avg power, total effort, etc. As a result I never use power match and find things to be great with the tacx. only reason I use the Garmin separately is for tracking other metrics on Garmin connect (VO2 etc)
