XCadey 2XPOWER Review - $280 to convert your crank to a dual-sided power meter (Vs. Assioma Duo)

- I'm in voluntary isolation to prevent the spread of the Coronavirus here in China, it's giving me time to do some videos.
Last year @gplama reviewed the single-sided XCadey power meter, this is the dual-sided version. If you're in China it''s a bargain of a power meter, but is it accurate? Let's take a look...
Shane has also well documented the inaccuracy or... 'weirdness' of Shimano-based right hand power meters. @kwakeham speculated this could be because of the asymmetric design of the latest Shimano crankarms. So, for this power meter I decided to install it on a 105 chainset, because the driveside crank arm is vertically symmetrical. I don't know if this was the reason for the perceived increase of accuracy, that's above my pay-grade, but it's food for thought.
Personally I think if you're in the market for a cheap power meter, just get a single-sided Chinese unit. (XCadey, Magene, etc.)

Best wishes to all those affected by the WuHan Coronavirus. I'm 800km away from the epicenter, but there's over 100 cases in my province and most people are confining themselves to their house 24/7. The streets around my apartment are deserted and supermarket shelves are often cleared out as quickly as they're restocked. I'm keeping about 10 days of food in the house for the five people currently living here. While this is a dreadful situation for all those affected, and has the potential to affect millions more, I think it's also important to accept that somethings are out of your control, and aside from washing your hands and wearing a mask, it's best just to go on with your life and keep an interest in things that interest you. Don't just watch the news about the virus all day, take a break and watch some RUclips content unrelated to the virus. Anyway, any questions about life here with the virus lemme know. Oh, and any questions about the XCadey are welcome too! :D
I bought an Xcadey powermeter crankarm, it is working perfect, same powernumbers as my Tacx!
@@fabianverolme Hello , what is your Tacx model?
@@thierryguerber9257 Tacx flux
Looking at the bright side.... now is the best time to cycle with the minimum traffic. ....😁😁😁
Nice I am looking for a new power meter! How come you never show your face????
XCadey didn't reply to my data review/report sent on their 2XPOWER R8000... Time well wasted. I didn't bother with a video review.
tldr; Same issues as every other R8000/R9100 RIGHT crank.
Date: June 27th 2019 - June 28th 2019
Unit Tested:
Shimano R8000 Ultegra Crank Set (Hollowtech II / 172.5mm)
ANT ID: 32670 R / 32670 L (Same ANT+ ID for both devices?)
ANT Manufacturer ID: 666 (Unassigned ID. Company not registered with ANT?)
ANT Model ID: 0
Firmware: 17 / 170
ANT Metrics: Power, Cadence, L/R Power, Pedal Smoothness, Torque Effectiveness.
Bluetooth: Power (L+R), Cadence.... tested to Zwift IOS. Won't connect to Garmin Edge over BLE.
Active Temperature Compensation: Unknown.
Claimed Accuracy: -/+ 2%
Observations:
- IOS App crashes. Needs to be more robust.
- Android App attempted to update the LEFT crank. App crashed leaving LEFT crank in DFU mode. Reset procedure worked.
- Crank needed a dual-side reset prior to the Lama Lab Test. It was reading 50%-50% balance. Wouldn't show up in the XCadey app. USB Power charger placed on both cranks for 5 seconds. Removed. Problem resolved. 2XPower unit then started reporting L/R balance %.
- USB Power charger needs careful placement on crankarms to stay connected. Especially on the right crank charge pod. Maybe a more inset design would resolve this.
Lama Lab Test Data:
analyze.dcrainmaker.com/#/public/a7a176eb-171f-4316-7493-7a12540cb3d5
Tacx NEO suffering ANT+ drops in this session - can be ignored by selecting non-drop zones of data. The stand out observation is the 2XPower suffers from typical Shimano based low power readings on the RIGHT crank within ERG mode on a static indoor trainer. The LEFT power channel was within stated power accuracy tolerance.
Power RIGHT Crank
15.69W LOW @250W ERG (Not good. Consistent with all other Shimano RIGHT crank power meters)
30W LOW @450W ERG (as above)
LEFT Crank:
2.28W LOW @250W ERG (-1.8% Excellent!)
2W LOW @450W ERG (-0.88% Excellent!)
- Cadence readings were good.
Questions:
Is the 2XPower ANT+ certified? The Manufacturer ID of "666" is not listed on thisisant.com
Both LEFT and RIGHT appear to have the same ANT ID, or does only the LEFT broadcast ANT+? Is this by design? Can the crank be used as LEFT only, or RIGHT only, or are they hard-coded to be linked for use only as a DUAL sided power meter?
Are the firmware engineers aware of the inherent issues with the asymmetry and coupling effect when using the Shimano four arm crankset (R8000/R91000/etc)? And how have they accounted for that in the firmware?
How are the units calibrated? Statically or dynamically?
Conclusions:
The XCADEY 2XPower suffers greatly from known issues with using Shimano cranksets as a base for a power meter, in particular the RIGHT crank. The LEFT crank arm appears to report power within the specified power ranges. These issues are most apparent when using ERG mode on a static trainer.
The mobile management apps need a little more work to ensure they don't crash. Power meter unit(s) also needing a reset to work correctly indicated issues with on-unit firmware robustness too.
You're doing (the cycling) god's work. Have you put any 105 based right-hand cranks through the llama lab test. I know not a lot of companies put power meters on a 'low end' crankset, but maybe the symmetrical design gives it some advantages? I know this stuff haunts you, but it could be the closure you're after. :D
@@ChinaCycling No 105 units tested. I installed the XCadey XPOWER-S yesterday (their spider) and the first dataset looks ballpark ok.
@@ChinaCycling The asymmetrical design of Shimano right crank is not depend on the model class of 105, ultegra or dura ace but rather the model generation. So 105 new model R7000 is asymmetrical right crank compare to the symmetrical in previous model (5800) you tested. You probably right about 105 (5800) do not suffer from low right power reading. I have Sigeyi Axpower on 105 5800 and it doesn't seem to suffer from low power reading on right side.
@@angusvoo9863 I think old generation ultegra (6800) was also asymmetrical, although it's subtle. The old 9000 Dura ace was definitely asymmetrical. But you're right, it's not as simple as 105 = symmetrical, because as you say, new 105 is also asymmetrical.
@@gplama would this be the same as the one with the xcadey x power s allow cranks ?
Great review again Joe! Thanks. I'll be looking online for the pedals.
Keep the great inexpensive product reviews coming. I plan to do a build in the future with nearly all parts from China.
does this work over bluetooth? i have a polar v650, or broadcast in only ANT
How do you pair l and right? My garmin only can connect to left or right, not both at the same time
Any information of Active Temperature compensation? Thanx
Sweet b-roll dude!
I would have preferred a bit more outdoors too, but current situations don't allow.
Sounds like Xcadey had cured Shimano crank's pain which no other power meter companies ever could do. Incredible!!!!
I'm glad your positive about the situation with the Corona virus I guess that's all you can do
Just one thing you've had the vennya bike for a while now do you still recommend this bike I found it a bit more pricier than say lightweight carbon bikes although they look like they have a very similar looking bike frame on their site anyway thanks there
In my opinion (and I'm just a guy on the internet) there's more to a carbon frame than just the weight. Maybe a $500 Chinese frame and a $1000 Chinese frame look the same, but may be very different. Or they may look different and perform the same. The things that really affect how a bike rides when it's new, and how it rides after 10,000km are pretty hard for most people to measure. However, sometimes, yes, it's exactly the same frame being sold with different paint jobs. Sometimes a factory will sell it's "B level" frames to other companies cheaper. So, they make 100 frames to the same standards, and then the bottom 20% (judged by weight, stiffness, finish, etc) get sold off to another brand. So... all in all it's super complicated. There are many super cheap good frames out there. But maybe you buy 10 frames and 1 is a dud. Now that I'm giving people advice, I tend to avoid those frames because the one guy who gets the dud is gonna be pissed and think I'm a liar. So yes, I still rate the Vanyar frame, because they seem to be pretty strict about quality control and if anything my preference in general is going towards more expensive Chinese frames. (Winspace, etc.)
I saw in some online website, they are selling xcadey 2x power left side only. Does it means it was unpaired it with right sided power meter and sold as left only?
Will this work with Tiagra 4700? Are 105 cranks different design apart from weight?
Did you manage to review Magene Ridge Dual? How does it compare to this one?
Where can you buy these?
Hi Champ
Have you seen the xcadey x power s allow cranks ? This seems interesting so wonder if you have looked into it already
Just one last question. Dis you ship the product there yourself and ship it back to get that price of 280 dollars?
I'm sure the Chinese handle the situation very seriously, I have more confidence in them than I do for our Western civilization for such matters.
On the XCadey subject I have the single side one and it's just perfect. Highly recommended.
Yeah. They're a pretty small company too. They need a bigger marketing department, because I think their stuff is ace.
Great video, I was wondering if Xcadey has a powermeter for the Sram Red etap AXS 12 speed crankset?
A spider-based one is in development. Coming soon.
Have you synced on a Wahoo elemnt or elemnt bolt? I had read there were some problems
I use an element bolt, no issues here.
So basically firmware update all of a sudden solved the right crank issue?
Thanks for the video
It's possible (however unlikely) that it was accurate all along... perhaps before my left leg really was a lot powerful than my right leg. I have no way to know because two things have changed. 1) I updated the firmware and 2) my legs got downgraded. It would have been sensible to test before updating the firmware, however, all that ultimately matters is post firmware update it is now accurate.
I have left crank , what's esle...,
Not sure if data totaly right , but if small différence 5-10w they change something for make nice/hard training?;
Just one think before i have srm max power in sprint +/-1380w with left crank for moment only +/- 1100 probably with high push accurency are more Bad , but... Nothing...
Great video, thanks!
I'm curious to see data between assioma and qcadey at 1000+ watts. Would it still be only little difference ?
Before I broke my leg 1000 watts needed a good breakfast and a bit of motivation. For now it's out of my reach. I will have to call the KOMunist.
No necessary at 1000+ because its impossible to ride over 5 sec at this power
Seems ok for the coin. Im just waiting well.hoping that xcadey or similar bring out a rival to the Assioma pedal for a great price.
I think it's gonna happen... but I think the Assiomas are already pretty cheap. I can only imagine a Chinese version being 20-30% cheaper, but - We shall see!
How come you purchased a brand new Shimano 105 Crank but got the last gen R5800 one? Or did you get it on purpose because the R7000 is also asymmetrical?
Lots of seller still have stock of the old one. I got it on purpose because it's symmetrical shape. (And it was cheaper - heyo!)
First off, stay safe out there!
I’m interested in the spider based model for Rotor 3D30, any insight into that?
I think all their spider based units are essentially the same, just the mounting metal and the chainring BCD metal are different. So, hopefully I can test one and it will be representative of them all. I want them to make one for new AXS. :D
@@ChinaCycling does the segiye power meter work for Shimano R8000?
@@zaahierstanley955 I have 0 hands-on experience with sigeyi. Only saw them at a bike show. In my comments I've heard people having success with them though.
watts.pw seems offline, any idea of what happened?
I guess being 'free' and having an application that is pretty server intense wasn't a great business model. I miss it too.
Is there a taobao link?
There's lots of sellers on there, including XCadey themselves. Just search for XCadey. :)
review some chinese tail light please
I guess you need to test an Ultegra or Dura Ace crank
Testing power meters isn't my forte, but there's definitely food for thought in this symmetrical crank arm design issue.
While you're apologizing for the intro I'm here thinking you didn't take it far enough.
Glad you liked it. I like just expressing myself in this videos, but I also don't wanna offend anyone or massacre their eardrums, so...it's a tough balance. ;)
Same here ...intro rocked
I find the products of the company XCadey interesting from the Price point. However, with my last purchase I had to learn that if you have a problem with them, you should not expect a solution. For Europe there is currently no proper help from the manufacturer.
Main problem is, as always, the quality assurance ex works. One can be lucky and everything fits or not. When I bought it, the electronics on the power meter were defective at the factory first. It was exchanged after months but against another series. There the charging cable plug had been produced wrong. So after 6 month no solution. But I would be happy if other customers would feel better.Mehr anzeigen Weniger anzeigen Antworten 1
Received xpower meter for Shimano DA 9000. Cannot connect with mobile phone. Xcadey said its a problem with their app so I can't update firmware. No support from them. Regrets.
Send me an email, address in channel about info. I'll see how I can help. If I recommend something and someone buys it, I consider it my responsibility to help you get the support you need. Email me!
@@ChinaCycling Hi. Thanks so much for your reply. Managed to get the firmware done by using another phone. For one reason or another it just couldn't connect to my Samsung s8 or Samsung Tab S3. So from now on I'll just use my friend's phone to get it done. The app developer has also assured me that they will be looking into it as well. Thanks so much for getting in touch. Really like your content by the way. You're doing a really good job. 👍👍👍
@@1270mothman how are things going with your unit ? Dis you get the single side or the 2 X? Thanx
Cool that a company tries to be soo competitive...I hope I get my pedal based IQ² PMs soon...
I'm also interested as to what the final IQ2 will be like.
Any Chinese pedal based power meter?
Aamir nagaria this
I think at least 2 companies are developing them, but none have been brought to market so far. Watch this space. Personally I think Assiomas are already pretty cheap. I can't imagine a Chinese version being more than 30-40% cheaper.
@@ChinaCycling right. 445 eur for assioma uno and 680 for duo version is responsible price. It is not cheap ( 4iiii left crank on Shimano 105 costs only 280 EUR ) but it is accurate and very reliable

I bought mine on futurumshop.nl Current price is 299 EUR , but quite often you get 20 EUR discount if you spend more than 100 EUR. So final price was just 279 EUR.
Great shop btw
Next time test the waterproof in the shower ok...))))

That intro...
165 mm ?
Short legs ?
I'm 1.68m tall and I think 165mm cranks are a lot more pleasant to ride than 170.
China Cycling Love short cranks, 187cm and using 170mm!
Bought the xpower. Started giving trouble the moment I installed it. Sent back to them postage borne by me. Sent back different version and the crank arm looks used. All this after 3months. One word, regret. RM 1550.00 DOWN THE DRAIN.
Damn. That sucks. What was the problem with the original?
@@ChinaCycling They said it was a problem with the accelerometer. The unit they sent now works but even though there is a battery level checker in their app. It just states 100 % even after using it on a couple of rides. This is a legitimate problem as I've seen someone else post it on the net. By the way KUDOS on your content posted. You're doing a great job. Keep vids coming.
