Correct

Hi Shane, so what happens to the readings/accuracy when the offset goes off during a ride!

Another question… (general) does the crank arm length need to be set on spider mounted pm’s?

Hey Shane

Did you ever get the 4th firmware? Any improvements?
Looking into this power meter now.

Hello, i just installed this powermeter on my Orbea Alma MTB. Is 3.24 the latest fw you have used?

32

I have 3.24 installed but i don’t really know how to test if it is accurate or not. This is my first powermeter.

33

So some numbers compared to my 2018 kickr in erg mode. I did a 23 min ride at 184 watts.

Kickr showed 184 watt average.
Sigeyi on Strava Showed 193 watt average.
Sigeyi on Bolt Showed 198 watt average.

I have no clue why i get different numbers from Strava and the Bolt. Should not Strava just show the exact same number as Bolt? I mean i upload the ride from Bolt to Strava…sooo…

Were there periods where you weren’t pedalling? Average power will be different if you include vs exclude zero values. I think Strava include zeroes in their averages, which would lower it.

No it was just a block at 184 watt. I started recording Sigeyi power on my Bolt after warm up.

I did a 1 hour workout today. Calibrated kickr and used backspinn calibrate method with the Sigeyi powermeter.

For some reason it worked out alot better this time. The difference was around 5% more power from Sigeyi powermeter than the Kickr. I am happy with that. I did not notice any drift during workout. So mabey fw 3.24 is good. Or mabey i need a longer workout to see the drift.

I will report back if i notice som strange things from my limited experince.

I am on FW 3.24 as well and I noticed that these huge power spikes of 2,000 + watts I used to get on my MTB are no longer there. So at the very least those are gone.

Have you noticed any problems with fw 3.24?

39

Nothing yet, I have been on fw 3.24 since May 3rd and have seen nothing but improvement. Its nice not having those huge power spikes in your ride.

I just did a 2 hour ride outside. From what i can tell power data seems spot on compared to heartrate and RPE. No spikes, no drift, no nothing strange at all from what i could see. Was fun to ride outside with power too!

Feeling quite good about this powermeter so far.

Any further news on these?

I dont see a Shimano road compatible one on their website?

42

I reached out to them because I am considering this PM and asked if they updated firmware to fix the offset re-calibration issue. Here is the response I got

"Thank you for your inquiry.
There may be some misunderstanding. We have fixed the bug you mentioned in v3. 0 several months ago. Please don’t worry about this. "

out of curiosity.: what’s your guys (planned) setup? I mean in terms of axle and cranks and so on?

XX1 Eagle Cranks, DUB BB, Boost. Will need to get a direct mount chainring for this PM.

45

Really curious if there is some more data on these units. Looks like a great low budget option for many different MTB cranks, and dual sided as a bonus :slight_smile:

Just a comment on customer service here. I ordered an Xcadey unit from a Aliexpress seller (i’ll have to check which one). Took for ever to get here due to COVID. This is on my trainer and working perfectly and tracking well for my uses.

I just ordered a Shimano m9100/8100 version for my new MTB directly from the Xcadey website. It shipped out right away and was 14 days to the US. They unffortunately sent a SRAM 3 Bolt version instead. They immediately responded on Facebook messenger to my chat, said they would send me a new one, asked me to send the wrong one back, and are reimbursing me the shipping cost. No questions, no pushing them for this outcome. I was very impressed with the service. If you’re looking at an Xcadey I recommend buying direct from their webshop.

It seems that for RF Next SL cranks that will be coming with me next bike there are not many options to add powermeter. So I am really interested in the development of both XCadey and Sigeyi spider versions that I am considering. Looking forward for some GPLama’s conclusions in this topic :wink:
