That’s a pretty big imbalance if you’re relying on left only power, actually

That’s true, but it’s also completely normal and what a lot of people see. Which is perfectly fine if you only have one PM. The problem comes when you’re trying to compare one PM to another, and at that point, it’s worth the extra money to buy duel sided.

Two things:
I used my pedals with the latest firmware for a 6 hour MTB race on Saturday and it’s showing 18:39 standing time, which would seem to be accurate.
I just noticed that the manual says only compatible with included cleats and Shimano SH51. I use SH56. This can’t be a problem, can it? As far as I know, they’re interchangeable.

I can’t imagine there’s any difference re: the pedals. The only difference is the 51 only releases in one direction and the 56 in multiple. It wouldn’t hurt to ask Favero, but I’d be really surprised if it matters.

had mine for a few days. So far, very pleased. Theyre right on with my kickr. I was previously having issues with a left side stages reading anywhere from 10-40w high, and wondered if it was possible my kickr was off. These have been right within the margin of error for 2 or 3 indoor rides and outdoor seems as expected. Havnt run it through the DCR tool yet but did an indoor ride on the kickr, on a bike with a stages double sided, and the new pedals. At quick glances, all 3 were all right where they should be.
Ill be interested to see how these stand up to cyclocross abuse. Thankfully theres a 2yr warranty and paid for on a CC that doubles the manufacturer warranty. If they dont die in 4 years of beating the crud outa them, they have my seal of approval
Shipping was really fast, I wanna say 3 days from italy to my doorstep in Maryland (although thankfully fedex “signed” for me, or I wouldnt have gotten them).
new firmware is up. 5.34 from 5.04. changelog is always the same “fixed minor bugs”. haven’t had a chance to ride yet (temps here have been insane) so cannot confirm any changes

has anyone compared stack height with Shimano XTR pedals? In the spec Assioma writes 11.2mm but I’ve read some reports that Shimano measures different (with cleats at 15.4mm) and that the power meter pedals are thicker, thus increasing stack height. Hard to believe PM pedals would be 4mm thinner than Shimano XTR. Ideally, I’d like to increase my stack height without having to buy shorter crank arms…

…hmmm shorter virtual cranks arms length at bottom of stroke but bigger when at the top, no? -hahahaha
Anyone using their Assioma’s on a mtb, with drops and jumps, Currently only have them on my gravel bike but kinda want to try them on my mtb but also don’t wanna wreck them

I used the original Assiomas with the SPD hack for years on gravel and MTB, but I don’t jump. I did smack the pedal on rocks several times and they’re still good. However, I was nervous that one day I’d destroy them, so I went to a spider power meter in my MTB.
The power meter is better protected in the axle on the MXs, but the axle is hollowed out. That doesn’t necessarily mean it’s weaker than the OG Assiomas, depends on diameter and material properties.
according to this site Shimano XTR are 5.1mm lower than Assioma Pro MX (v1), so stack height including cleats of the V1 Assiomas would be about 20mm (if XTRs are 15.4 on this site). It’s not clear to me, if that’s right because they only show the differences in their table and not absolute stack values of each pedal.
@606david I must admit I haven’t thought of that. I assume you never made a mistake, good for you.
i thought it was a genius idea ALSO, till my engineering mind thought it through. …was a good try. guess it came across too ‘snarky commentary’ but whats 5mm between forum friends!
dont be dissuaded this is good info/debate on here. Lama, ya never know if someone else can use the info, later
For those of you who have purchased these pedals, do the clip in and out the same as the Shimano SPD (M520)? I’m asking because I did not get along my covid-era Look X Track pedals at all.
Feels the same to me.

maybe I was just a bit too sensitive - we’re good.
I recently got a bike fit and at 187cm never quesetioned riding 175mm cranks. But I swear 170 felt so much better on the jig for some reason. Before I swap my RED cranks and XX1 on the MTB, I wanted to explore other options. But yeah, didn’t think through that stack heigth affects the whole pedal stroke. Doesn’t make much sense this way. Need to find another reason to buy the Assiomas 
Thanks for the feedback.

I have been using them on my EE7 and hit medium-sized jumps with them and can report no issues as of yet. I have also had so many rock strikes since installation I dont care to talk about it (this is normal for me). I think so far they are super solid, this is coming from a 200lb rider that will blast through almost anything on the trail.
They clip the same as my XT pedals and are more secure refined feeling than my XTR pedals.

You might not want to go shorter on the MTB. I am 6’1” (185 cm) with a 33” (84 cm) inseam. I’ve gone down to 165 mm cranks on my road bike to allow me to tilt my hips forward better and get more aero. But I noticed the reduced leverage I have, so I need to use a higher cadence for the same power (assuming using the same gear). I have 175 mm on my MTB and have no desire to go shorter. My gravel bike is setup to be fairly aero and I’m using 170 and also have no desire to go shorter on that bike.
So know that you’ll have reduced torque with a shorter crank, which you might not want on an MTB.
point of reference regarding battery life. i got my first “low battery” notification yesterday on my edge 1040 solar. 44 hours of active riding according to garmin connect. not bad, but not quite the 60 hours per spec either. manual says low battery warning means there’s another 8 hours left, which would put me at 52. i’ll take it

QUESTION: can you link an old left assioma pedal to a new right MX pedal?
about to buy a new right duo-shi to get dual sided power meter but then thought maybe a new right MX pedal would be worth the upgrade? i can and have unlink and relink different sets of the older style assiomas…
thx
