Pbase, same for me. I have about 10 hours of mtb use with my hacked pedals with several pedal strikes and no apparent damage or issues so far.

Good evening everyone do you know if the Shimano XT PD-M8100 SPD Pedals are comparable?

I got two sets of Assioma Shi Duo. Both sets malfunctioned.
My pedals are Shimano PD-EH500. Bought brand new.
Got a new set of Assioma Shi. Installed smoothly without any problem but Assioma did not work. I contacted Favero. They decided to send me a new set of Assioma Shi. This time, the set worked for one day and failed on the next day. I contacted Favero again and provided as much info as I could. Today they came back saying that I used incompatible pedals so it would not be covered by warranty. I need to pay them to purchase a new set.
All I did was pulling out the original spindles from the pedals and put Assioma Shi in. The fit was 100% perfect.
Symptoms of the first set of Assioma Shi:
After installation, calibration was essentially impossible. Maybe I could get one successful calibration in 50 tries. Even if the calibration worked, power readings would be intermittent and incorrect. When there’s a power reading, it’s way too high like 1000+ watt while I felt I was only doing 100w. Cadence worked fine.
Symptoms of the second set of Assioma Shi:
Calibration worked most of the time. However, cadence and power readings were intermittent and incorrect. When there’s a power reading, it’s too low.
I need a second opinion please. I’ve tried the following:
- adding washers to both sides
- calibrating successfully many times in a row (including calibrating through my bike computer, Garmin Edge 830)
- re-instailling Assioma Shi
- converting to Uno, then back to Duo
- flashing to the latest firmware, of course
I have exhausted my options except installing them in another set of pedals. I can probably try this. I just don’t feel the official response from Favero makes sense.
This is very strange. Mine worked perfectly.
hello! has anybody tried using Look xtrack or xtrack race pedals for this hack? would love to hear some feedback

were you able to fit xtracks into the assiomas?
I got a reply from Favero that either would void the warranty:
- if you use the pedals on a mountain bike
- if you use “incompatible” pedals. The only compatible pedals are those listed on their website
I did both at the same time. Therefore I’m on my own.
I would caution readers of this thread that you may be risking your warranty. Also, I’m curious that even if your Assioma works fine, whether the readings are accurate.
I put PD-A520 on the Duo-shi. The shafts measure almost identical in diameter, with the duo-shi being slightly smaller within 0.05-0.1mm between the outer and inner bearing locations. I don’t have to cut up my shoes! There is about 3-4mm clearance between the grips on my shoes and the due-shi pods.
Q-Factor: 66mm
Total Weight: 355g (both spindles and both pedals) (pedals alone weigh 159g)
Let me know if you want to see something specific, I took a fair number of measurements and photos.

One would assume you’d just tell a little fib and say they were in a compatible set of pedals wouldn’t you? I have mine in some mtb pedals and the readings are almost the same as my kickr

Thanks for the info. I was trying to help them figure out the exact problem. From your and other people’s experience, perhaps using MTB pedals is fine, but using them on a MTB is the problem. Favero replied to me and said they’re making Assioma for MTB now.
I’ll test the sensors on a road bike and figure out.
They said they’re making an assioma for mtb? Did they give any more details like when that might launch?
They did not. They just told me to check their social media from time to time.

Sounds more like “Zoon” than soon
Figure I can finally chime in here. Did the mod with the XPedo MForce 8, and Shimano XC702 shoes. Pedals swapped in 5 minutes, the shoes did require a little bit of trimming. Doing it again, I’d do it all with a sharp razor blade, dremel made a mess.
The Assiomas and my TacX Neo2T read within 1W of each other reliably over multiple rides. Outside I am using them (so far) for milder non-technical trail riding and training for XCM so haven’t banged them on anything yet.
Super easy, very happy.

No. I had to go with Issi Flash 3s. It was an easy swap and I am very happy with the resulting spd compatible power meter pedals.

Has anybody tried this with Look X-Track pedal bodies with success?
So when will favero come out with their own spd power pedals since there clearly is a demand for them?

thanks! did the same with ISSI flash 3s. flawless swap
Do you see any concern about data accuracy/consistency? Would you reccomend the combo DUo shi + Es600?
