For training purposes, I think consistency is more important than accuracy. Even if it wasn't possible to adjust the 6% offset, it's good to know that it's consistent.

This is honestly a piece of kit for those like myself who aren't athletes, aren't aspiring to be athletes, and just want something to track overall fitness. I'd been looking at getting a power meter since before I bought my current Roubaix Comp and now I have an option that integrates seamlessly into my Rival AXS groupset, right on! And the fact that it works as well as something definitely much more expensive makes me smile. I can't wait to buy one for my bike and really begin to track my progress on my fitness rides. Thanks for sharing Shane!

Awesome review! Was waiting for real numbers on this before I go out and buy it. But I still have a view doubts about the compatability. I have a force crankset and think about just getting the rival upgrade kit. But it would be interesting if the asymmetric stiffness and weight actually have an influence on performance, as well as on power readings. Even though its the non drive side, i could imagine the stiffness difference has an effect on your right and left side power distribution. I would really be interested in a short test of a asymmetric setup and if the power reading still makes sense or if it's thrown off by an offset or just gibberish...

I have two Rival PM spindles: one reads extremely low (to the tune of 6%) and the other is pretty darn good at factory slope. I'm curious what your slope values looked like before and after the 6% correction. SRAM meters are all over the place as I've also had a Force AXS Quarq spider that read almost 10% lower than a KICKR... so like actually 12% low because of drivetrain loss.

I just got one, I ust got a new bike with Sram Rival and the crankset that came with it was the wrong cranklength and not the gearing I wanted. The Crankset was €122 without Powermeter and €270 with, that's not even €150 difference that's a lot less than any other Powermeter! It's even less than the 4iiii Precision 3 I have on my last bike. From my first test, it's within 10 watts of the 4iiii, so for me that's good enough especially because I don't really do powertraining, I just like it for not going to hard on long climbs.

Thanks, Shane! Any updates from SRAM on the 6%? In the meantime, I have a few questions: - I see you have firmware version 1.1.13. I just checked and mine shows up to date at 1.1.12. Did you get a test version from SRAM? - I use a Garmin watch and head unit. Is there any advantage to doing the ‘Calibrate’ function on the watch, head unit, or zeroing in the SRAM app? I wasn’t sure whether the Garmin calibrate function actually affects the power meter itself or only allows the Garmin unit to know how much it needs to offset values given the power meter’s state - Do you think MagicZero can be added in a firmware update?
@gplama 2 роки тому
- No word back on the 6%. - Not sure on the firmware version side of things. - Calibration (or zeroing) only needs to be done with one device. It's then updated/stored on the meter. - MagicZero... unlikely. I'm not sure if it's technically possible with a spindle meter. They also need to differentiate the lower/budget units from the other offerings. If they make the low end units really really good, why buy the more expensive ones? :)

@Shane Miller - GPLama Hi Shane. Thanks for this great review. Shame I only found it after ordering this blindly to cross match it with my SRAM Force ASX 2x 43/30 Wide crankset. I would be much more confident to go ahead with this having seen your Rival/Red demonstration. Like you have said - this is probably the only available option apart from dual pedal based PMs for my gravel bike. Just wanted to confirm that the Wide version (labeled as Quark Rival ASX 1 Wide Upgrade at Bikebug) works well with my Force 2x 43/30. Looks like you are showing Cadence data collected from this power meter. I am unable to display the Cadence rate on my Wahoo Element Bolt v2 from the Quark power meter. Bolt recognizes the Quark PM as a power source only. I had to pair separate Wahoo cadence sensor to get the data. Is this a problem with Wahoo Bolt only? How did you manage to get the Cadence data from Quark PM?
@gplama 2 роки тому
Cadence data should come through with the paired power sensor.
@TadeuszPiszel 2 роки тому
@@gplama thanks. That's what I was expecting to see. Unfortunately cadence field was not showing on my display when only powermeter was paired. I was also unable to manually add this field to my screen. Perhaps it's just a quirk with Bolt V2 and Quark Rival PM combination. Not a biggie for me since I already had a spare cadence sensor but it would be nice to get rid of redundancy.
@TadeuszPiszel 2 роки тому
@@gplama it must have been some kind of a glitch. I am able now to show cadence data directly from the Quarq powermeter. Firstly I had to enable Cadence field on the Bolts screen by pairing it with Wahoo cadence sensor. Once the Cadence field was showing on the main screen I have uninstalled the Wahoo sensor (Forget sensor) and now cadence is shown without pairing any other sensor - presumably reported by Quarq powermeter. It's just bizarre that I wasn't able to add Cadence field manually earlier on. I have found an old thread on internet discussing similar problem back in 2017. groups.google.com/g/wahoo-elemnt-users/c/XKXvY0kjWkI Hopefully this can help someone with similar issue in the future.

OK, now to the one question I have based on the review, and I know you are still waiting on more information on them.

Excellent review as always Shane! I’m in the market for a dual sided power meter pedal set for SPD (was interested in the Favero until seeing the extra Q-factor in your review). Have u found the Garmin pedals reliable? I moved away from Garmin head units due to all the issues my wife and I have had with reliability (or lack there of) of them and am hesitant to drop the coin back into Garmin. I’m well aware that all products can have issues, we maybe have just had a lot of bad luck with Garmin products
@gplama 2 роки тому
SPD = MTB. SPD-SL = Road pedals. The Garmin Rally RS (SPD-SL) are a better option in regard to q-factor compared to the DUO-Shi. As for the power accuracy.... it's complicated. The Garmin meter would likely be fine for most people. I'm having ongoing issues with drift after high power sprints (>1200W).

Actually, I dont understand why this should be done repeatedly. I guess what you show here tell us this is not necessary, however, a precise initial calibration has to be done instead?
@gplama Рік тому
You'll find most meters that don't have auto-cal will advise a manual zero before every ride. It shouldn't be necessary for every ride if the conditions are the same as the previous manual zero. If being confident with the accuracy without calibration or faff like this is a requirement, this isn't the power meter to use.

It's a single sided meter... so the best you can do to account for an imbalance is to scale it up/down. If you know you have an imbalance then a single sided meter isn't the best option, imo.

@@gplama - I understand it’s a single sided meter, however you can still correct for imbalance if you know what the bias is…I would speculate that most people have an imbalance across the full range of power you deliver on a bike.

I am a great fan of that channel specifically, and more other channels like this , but I can’t understand why to use the term “inaccuracies” for those wattage differences ?

@Shane Miller thanks for the review. Any update from SRAM on why the power meter reads 6% high? I want to swap out my R8000 drivetrain for SRAM Force AXS 1x but with this Rival power meter crankset. I need an aluminum crankset because I use pedal extenders which break carbon cranks. Also, I have a set of Favero Assioma Duos which I could use to calibrate the SRAM meter. My left/right power is about 47%/53% right now at FTP wattages, so it seems like it would be better to calibrate the SRAM meter against total power (both Assiomas) rather than just the left pedal. What do you think? The Assiomas are great but I'm going with TIME ATAC pedals on both road and MTB because those are much better for my knees.
@gplama 2 роки тому
Still nothing back on this subject from them. As for calibrating against total power.... entirely your call. Not something I'd do myself due to the variability in L/R balance.

My Quarq Dzero was reading 6% lower than everything I compared it to ;) It was one of the early ones (2017). Static calibration was fixing it by +4% and I bumped it another 2% by doing long term dynamic comparisons with other power sources. Only after that my power data started to make sense. That's why I think every power meter should have an option to fine tune the calibration if someone have good comparison data to correct it.

Even without adjusting 6% the only really important thing is that it's measuring consistently which it was. You could just have an FTP equivalent on each meter.

True, but adjusting your FTP based on the equipment used isn't an ideal scenario. If a meter is consistent then it should be made to be consistently accurate.
@davidkaplan5517 10 місяців тому
@@gplama you wouldn't need to adjust your FTP as in have 2 FTP tests, you could just know that your adjusted FTP on one of the meters is x and it's y on the other. Ultimately it makes no difference as long as it's consistent. One thing I think would be great for you to highlight in videos is that these findings are only accurate and true to the specific meters you're testing. Favor Assioma pedals and Wahoo Kickrs and SRAM Rival power meters are not all going to be consistent to their cousins from the same brand and build.
