Most accurate chinese powermeter?
« on: January 19, 2026, 05:42:39 AM »
There are so many threads on powermters here at CT, but so far I haven't seen sth. like a complete market overview of chinese powermeters and infos about their accuracy.
I think an overview would be great, also for other readers here.

So far I run Power2Max from Dresden Germany on my bikes and my son uses SRM (the original inventor of powermeters and still the gold standart IMHO) on his track bike and TT, and Power2Max and Shimano on road bikes.
Want a powermeter on my track bike, tend to Magene plus an adaptor for 144 BCD.

But what are all the options and which one wins when accuracy counts more than best price?

I am on the same boat and quite peaky about the powermeter I use... on P2Max as my main PM so far. I expected XCadey to get better with a 2nd gen power meter but recent reviews were disappointing. I have Magene P505 on my TT bike and quite happy with it but wanted a spider-only option which would be cheaper and lighter.

I wouldn't look into other options unless the PM was tested by GPLama/DCRainmaker. If you don't mind a little bit extra weight, go for P515 - it is the best Chineese power meter you could get for a reasonable price. Another decent option is SIGEYI Axo, but at this price point it is worth to pay a bit extra and get P2Max, too bad I didn't have enough cash to get another one during Black Friday :(

Magene are the only ones so far who seemingly haven't made a dud. Unfortinately, they're also the only ones who don't make their power meters in a variety of interfaces. Just like quarq, you have to buy it with their own cranks.

I run a Magene P505 base and I haven't had any catastrophic issues, but I also haven't done a deep comparison with a second or third source.

They DO sell them with different interfaces... I have the 3 bolt P505...

I have been wondering if anyone had done any testing with the Elilee EK-01 power meter?  I have searched and could not find any.  Maybe my bad searching skills.

Thanks

Not anymore. At least I can't find equivalent P515 on Ali. The remains of p505 spiders cost ridicously more compared to the crankset which kills entire reason to go for Chineese PM.

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.

The old sigeyi model was good once upon a time. If they haven't changed anything about it since PT and GPLama tested it, it could still be.

I do believe that the P505 spider is available for sell. I can’t make a link
But go to the Magene web page and search P505 Spider and it will come up.  $349 usd

Magene makes an Easton style spider?

They never made them in easton.

The p505 spider and p505 base set can still be searched for on their websites, but they are all listed out of stock. Most likely this isn't because they are still making them and don't currently have stock, but because they stopped making them and their IT just hasn't done their housekeeping and removed those listings from their websites.

Toxin. I had not tried to buy one. It did shock me to see it on their site.  I would be shocked to see them still producing the P505.  I sure wish they would make the P515 like this. 

**** Update from Magene***
They no longer make the P505 and p515 only works with their alloy cranks for 24mm option.  This is just as most of us here thought and I want to let you know of their verification.

I regret not buying more 3 bolt Magene power meter spiders when they were on clearance. Plus they had mounts for both 3 and 5 bolt configurations.

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
