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.
I was going to measure them both with/without cleats a little while back but whoever it was that posted a similar question decided to add some snarky commentary about reviewers screwing this up, so I didn’t bother going out of my way to answer their question.
A quick check now shows a set of Shimano SPD pedals (not sure which model) have a pedal stack of ~8.8mm.
I need to look into why some companies include cleats in their stack height listings and some don’t.

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
Do you mean using two different styles of pedal? Surely this would put your feet in different positions? Or is that not what you meant?
Even an assioma duo that has been converted surely could put your feet in subtlety different positions even if using the same cleat system?

That’s definitely a question for Assioma support. However, I don’t think you want to do that. The axles and pedal bodies will be different, putting your foot in a different side to side and up and down position. This is likely to lead to issues with your body over time. Not worth it
I don’t think it’s a good idea to mix them as they have different q-factors and stack heights. Not to mention one uses road cleats and the other MTB ones.
Why would you do that?
I’d be very surprised if you could do that even if you wanted to as I think the technology and firmware is pretty different.
You should just buy a new set of double sided MX-2 
So I used mine now for some time, had some issues in the beginning with dropouts with my Garming 1040, but this resolved after a FW upgrade and is now stable, the Power numbers seem to be inline with the Favero UNO I have. The pedals seem sturdy and work well, never had any issue on gravel. I really like the new design without the Pods they look really good.
Currently they are on my road bike, because my UNOS will not charge anymore… And I’m not that happy with the responsiveness of the support, took about 1 week to get a reply, with the standard send pictures, request and now it’s again 4 Working days of waiting for the next response. Wasn’t as long in the Spring when I needed the support, so I hope it’s just a high load for them currently…

well as my summer riding season starts to wind down i thought i’d check in and let everyone know that i continue to be absolutely thrilled with my mx-2’s. i’ve been using them since may 1st, have had to charge them a whopping ONE time as of today and they’ve been utterly flawless the entire time. i could not be happier.
the seating vs standing issue has long since been resolved (i see maybe 3-4 minutes of standing in a 3hr ride, which is inline with expectations) and i simply cannot find anything negative to say here. i don’t use the app at all except to occasionally check for fw updates. just get to the trailhead, calibrate via my edge 1040 and off i go. i’ve hit rocks, roots, squirrels (poor thing) and these things didn’t blink an eye. just rock solid perfect data ride after ride. i’ve even gotten used to the cleats (vs eggbeaters) and man they sure seem to be lasting a lot longer. i typically have to replace the eggbeater cleats 3x per season (they’re a VERY soft brass 
) but here i’m still on the oem cleats and they seem like they’ll last me well into next year as well.
idk man when i had my garmin rallys they were nice but after a few weeks i started to have that dreaded feeling that they just weren’t worth the cost and i may have made a mistake. the assioma pro mx-2 on the other hand, are worth every penny. these guys…know what they’re doing…
