I recorded the Sigeyi with my Wahoo Elemnt and the Assioma with the Wahoo App on my iPhone. I would expect those two, being from the same company, to handle it the same. ---

Took it for a ride this morning and seems to work really well. ---

I did exactly that. Recorded the Duos with the Wahoo Elmnt and the AXO with the app. And still the Duos are not recognizing short stops in pedaling, thus registering power when my legs aren’t moving but I am applying force to the pedals. (Note the cadence shown is for the Duos, which often isn’t at zero despite the AXO registering zero and I know that I completely stopped pedaling) ![image](https://global.discourse-cdn.com/trainerroad/original/3X/9/2/92a7b4839aedccb6e2f13b3aac3e2b5360a0cee6.jpeg) ![image](https://global.discourse-cdn.com/trainerroad/original/3X/1/8/1811581a1d0e34d01730e747e3c9a7ab432401a5.jpeg) ![image](https://global.discourse-cdn.com/trainerroad/original/3X/f/2/f2e65066433b20a11f90839f53be8d328960ddf6.jpeg) ---

Hi everyone, looks like there is a version of the power meter with the cr2032 battery on sale on Sigeyi website. It is called the Axocc. Does anyone have experience with it? Maybe @gpl knows? Especially interested to know if it is the same accuracy, what is the battery life and the durability of the seal ( I plan to put it on a gravel bike). Thanks! ---

@gpl yo, I think I saw in your MTB vid that you’re using a Drop-Stop A profile chainring on an otherwise shimano 12spd drivetrain. Technically not the correct ring, but it does mostly work. FYI. ![image](https://global.discourse-cdn.com/trainerroad/original/3X/8/6/86a6f67b3ae14813d885fc7467d3b45f4ce57d76.jpeg) ---

Recieved a Sigeyi AXO 8-100 version for my Shimano XTR M9100 crank. Bought an XT chainring to work with this BCD - I checked with a torque wrench when undoing that T15 bolts from the original spider and looks as though they’re tightened to 4.4Nm. Anyway, after one short ride outdoors I borrowed a set of Assioma DUOs from a friend and tested the Sigeyi against them on a set of rollers. Not sure what I should think of these results! After 13 minutes of riding I performed a zero offset, shown screenshots are after that. The Sigeyi seems to be reading 2% lower in the steady state before the first seated sprint. The sprint itself is about 12.5% lower compared to the Assiomas with the peak being 4.5% lower. From after the sprint to the race-like attack Sigeyi on the other hand goes about 0.7% higher. The attack though is pretty much spot on the whole way. After that I tried some low cadence effort (~65rpm @ 160W), at which the Sigeyi is reading 0.8% higher, and high cadence (~115rpm @ 118W), there it’s pretty much spot on. ![Sigeyi AXO vs Assioma DUO_1](https://global.discourse-cdn.com/trainerroad/original/3X/3/f/3fce7495eeb177188efbdb5c12d367a85dfd0a5c.png) ![Sigeyi AXO vs Assioma DUO_2](https://global.discourse-cdn.com/trainerroad/original/3X/7/5/75bcd9fb3a7933c7ded449f31333800df7907a57.png) I probably won’t be scaling it up at least for now. I’ll have to return the Assiomas today, so no more testing’s possible by me, but to be honest, I expected the Sigeyi to perform better. ---

Anytime you re/install a power meter, you should do a couple of sprints with it to settle in the part. Then do your zeroing. Only after that would I start comparing data. ---

Of course, zero offset performed on both Sigeyi and Favero. ---

I did my testing on rollers, so I couldn’t put down a ton of power, but I did two seated sprints before zero offsetting them. Though, looking at the results again it seems as the unit got way more accurate after the first sprint performed after the steady state efforts. Unfortunately I don’t have a way to retest, whether the Sigeyi really got better, as I had to return the borrowed Assiomas the day after. ---

Hi there, sorry to pick this up so long after you posted. Can you advise on the part number for the 8 bolt XT chainring you found? I don’t know if I’m being thick but I’m really struggling to find one. I’ve found a really good deal on a AXO-SHIMANO-MTB-8-100 but conscious of the issues you pointed out, and also don’t want to but a power meter for which the chainrings no longer exist… ---

Hi there, please can you advise the parts number on the XT chainring you used? I don’t know whether it’s the images on the Shimano website but I can’t see where the 8 x T15 bolts go through. Do they go through the rear as per the red circles on the image below? ![image](https://global.discourse-cdn.com/trainerroad/original/3X/f/3/f3e8aa8a2d0f2fd0fffbbaf6dfa2136352e88eaf.jpeg) ---

Have a look at the second photo. 8 torx bolts are on the rear on the crm85. As long as you use a good quality torx head it’ll be perfectly fine. The SLX and XT chainrings for the M7100? And M8100 series are interchangeable. M6100 looks similar but I’m not confident it’d be compatible. > **[Shimano XT SM-CRM85 Chainring](https://www.excelsports.com/shimano-xt-sm-crm85-chainring)** > > Following in the footsteps of Shimano XTR M9100 12-speed, the XT M8100 series moves to a direct mount crank arm/chainring sy... Also thanks for reminding me - I should probably get a spare chainring 😀 ---

Awesome, thank you, wish Shimano showed the same photos on their website as you can see the rear view. Are you pleased with how the Sigeyi has been performing? ETA - I am impatient idiot, they show you on the 360 degree rotational video on the Shimano site, but not the photos… ---

Hi, yes, this one will work, just like every FC-Mx1x0-1 series chainrings apart from the XTR level ones. The T15 is nowhere to be found in technical specs as Shimano probably doesn’t want us to remove the chainring from the original spider – you’ll need a T15 bit/screwdriver with a hole (it’s the ‘security’ kind of T15) to remove it. čt 13. 4. 2023 v 11:00 odesílatel swgregg via TrainerRoad Forum \<[notifications@trainerroad.discoursemail.com](mailto:notifications@trainerroad.discoursemail.com)\> napsal: ---

Yeah still extremely happy with it. Is ball park with my 4iiii on the road bike, I haven’t done any specific comparisons (but GPLama I believe gave it the thumbs up so that’s good enough for me) Battery life is amazing on the thing! ---

Is anyone else experiencing a large amount of drift due to temperature changes? I’m seeing a roughly 50 watt difference when it’s colder (55 degrees F) vs hotter (80 degrees F). When I start a ride in the morning, the SIGEYI reads low. I calibrate it and it’s accurate enough. I start riding and as the day gets hotter the power reading starts drifting up to the point where it’s clearly reading too high. If I calibrate it again it’s back to reading accurately. Power meters are supposed to automatically adjust to temperature changes and mine isn’t doing that. ---

I’ve got two (and have just swapped my Shimano one with a mate) and none have the drift issue. It might be the temperature swings aren’t enough. Is the firmware up to date?
