Most accurate chinese powermeter?

[glepore]

I run primarily Quarq, and have previously used SRM's. I'm very happy with a Sigeyi AXO, but it seems that everyone's move to "lightweight" pm's has been a bust. I suspect it'll sort out in time, Sigeyi went thru multiple firmware changes a few years back when the AXO first arrived, and now they're rock solid.

I don't have anything to add aside from Magene being trustworthy and Xcadey leaving accuracy to random chance which is a shame, however power2max eu shop recently had a massive price cut as high as 250€ on all of their products if I'm not mistaken and their 144 bcd track spider is now 440€ for the ng eco. Road ng eco spiders are now 340€, ng spiders 540€. For NA things are looking less rosy

Wow, did not see it coming. Unless all these numerous sub 250 EUR spider get fixed there is very little reason to go for Chinese PM, as P2Max is pretty much second most reliable power meter after SRM and you can get any crank interface you want.

I wasn't aware of this price drop; I wonder if more and more inexpensive powermeters on the market were the reason for P2M to take this step. Good news for cyclists, at least!

I have a set of carbon cranks w/ 24mm titanium spindle from Peter at XM Carbon Speed that have been collecting dust since the summer. Can't seem to decide on an Easton style PM that will be reliable.

Right now I run a variety of PMs from Sram/Quarq and 3 from Magene. All are reliable and consistent across the board.

What's the verdict on Xcadey and Sigeyi? GPLama got me nervous.

Hi Patrick,

No Chinese option, but in terms of reliability, I vote for Power2max. I have three P2M, including a Lexon Carbon crank with Easton interface—all of them work flawlessly. The power meters are manufactured in Germany, which is why the price is higher in comparison.

I don't know how shipping/customs to the US works out, but it might be an option for you. Or you could become a US ambassador for P2M

Absolute fan of power2max, unfortunately they don't have a SRAM 8 bolt version, so currently not riding one of the p2m, best accuracy in my eyes. For the price of 100€ more than Magene, I'd always take p2m

I've been happy with my Sigeyi Axo, power still matches very close to my Power2max after a year of use. Needed 1.5% upscaling  from the beginning (or my power2max needs 1.5% downscaling who knows). But the most important thing is that it's consistent.

The battery lasts so long when I think it's probably close to empty and check it's at about 50%.

Not sure how well this works but I did stumble across this for 8 bolt with P2M.

Coospo s10

I think this one is interesting. Apart from the temperature range the specs are extremely similar to the Thinkrider PP5.
Personally, I have been extremely satisfied with the (data) quality of my Coospo H9Z. It has been way better than a Polar H10 I once had and any other HRM I have had.
In Coospo’s comparison against the Favero pedals it looks like they did some sort of sprint/acceleration with a decent result. In contrast to this is the data example from the Thinkrider PP5 page. That one is done pretty much as a steady state effort and that shouldn’t be that much of a challenge to get right.
Okay, Coospo does not show any values for axis, and there most certainly is no guarantee that the data is true. I think the recent GPLama reviews have shown us that most manufacturers own data and testing cannot be trusted.

That Coospo power meter is the cheapest I've seen, from any brand

Anyone can make a graphic like that in few minutes.

All those news random power meters look like xcadey clones, same charging port etc. Probably all made in same factory to get rid of old stock.

So far SIGEYI AXO 1st gen looks pretty good, and gives me reliable results for my daily rides.
The 2nd gen (AXO SL) looks even better and slightly lighter, meanwhile not a huge increase in price.

And there is no stupid registration nor region lock, unlike Magene, just plug and go.

I also owned Shimano version SIGEYI power meter (send the crankset to their factory to be modified), the result is pretty bad.
The left/right balance seems not working correctly and results very unreliable power numbers (maybe resulted by temperature), and eventually the batteries wear at different level.

I guess the newer Shimano's official power meter design will be much better (strain gauges on both sides of the drive-side crank), but I didn't think one would consider Shimano PMs due to their price and weight.

I stick with favero, no risk of inaccurate measures and flawlessly regarding switching..
prices have come down , too..
So, if there is not a massive price drop on chinese products, why bother?

Because in my country at least (Australia), the Thinkrider (85USD) is less than 1/10th the cost of a set of Faveros (900USD). If it is just as good, or nearly as good, it's an opportunity for a substantial saving.

Secondly, I previously had a pair of Faveros where the bearings disintegrated, wore into the axle and ruined the pedal spindle. Best they could offer (out of warranty, admittedly), was €50 off a new pair. That really put me off power meter pedals, at least with spiders there are no bearings or other wear items to worry about.

but this thinkrider works good? because it's so cheap...
