Favero Assioma Pro MX In-Depth Review: Best MTB Power Pedal?

Favero has finally officially announced their new SPD Favero Assioma variant, called the Favero Assioma Pro MX-2 MTB. I say ‘finally officially’, because the unit was actually non-announced back in November or so on their site. And that followed a year or two of teasing about it. And even when it showed up on their site back in November, it was only for Italian folks to order in a public beta.
But, as of today, anyone can buy one - and it unquestionably delivers the biggest bang for your buck for an SPD-based pedal power meter, or for that matter, any pedal based power meter. In this review I’ll dive though my usage over the last few months, including plenty of accuracy testing, new features and more.

Best news I've heard in a long time! Faviora user for over 6 years without an issue and have been holding out buying MTB Garmin pedals in hope of this. Thanks Ray for the awesome review.

[@veganpotterthevegan]

I couldn't wait and hate that I'm on Garmins😂

[@bilginaydin9756]

Me too I couldn’t even wait for Garmin. I started with Xpower SRM 1st generation and always trouble with discharging battery when not in use, then added Garmin XC (converted from Vector 3) with over 200€ just for the pedal bodies but in total cheaper than Rallye. It’s a pity it took so long for Assioma

[@celery_annihilator]

The Garmin’s suck.

[@mosantos4172]

Thanks Ray! Happy Assioma Duo user since 2018. I even mounted those (Duo) on my MTB for a race held mostly on forest roads. Still work (and look) like day one. The only problem was loosing the charging cables, but I had plenty of micro USB cables at home so I just ordered the overpriced connector... MX out of stock for 2 months!!!

[@steven871]

Great review. Thank you. Looking forward to getting Favors when I can afford them. Really appreciate your review.

Bought this pedal after watching your review. I've been using this MTB Power Pedal for over one month. During my 1,200 km riding, this power pedal performs well.

[@cvdavis]

Great review as always.

Thanks! These look like a very compelling option for my gravel and mountain bikes.

[@edgartrujillo4128]

This is awesome! I've been using the Assioma Duo Shi for about two years for my road bike and I am very happy with them. I've been wanting to find a similar solution for my gravel bike and this is it.

[@johnmcmillan1186]

I’ve had duos for a couple years and love them. I’m planning to do more gravel this season and have needed an SPD solution. This is what I was hoping for!

[@coreyreeder3549]

I got their road pedals a couple of years ago, but I definitely would have gone for these if they were available. Great to see this on the market

[@lidarman2]

I tried to order Garmin pedals from Competitive cyclist using 20% birthday discount and they said Garmin will not allow discounts (so much for my birthday fun). So then I ordered the Garmins from REI with their 20% coupon and two days later my order was cancelled claiming out of stock. (So much for my birthday fun). Today I found some Faveros and got em arriving on Saturday, saving a lot of cash. Gonna have some birthday fun!!. :)

[@BrianRPaterson]

I think you made the right call. Happy Birthday!

Great work mate 👍

[@stephenbetley9596]

Love my Assiomas. Will be adding these to my collection as soon as I can get my grubby little mitts on them. Heopefully this is a naming system that Favero will be continuing and that with the new spindle technology a Favero Assioma Pro RD is now in the pipeline. If they can do that and have it with interchangeable bodies even better. If not then just with standard q-factors will be fine. Hopefully a good year for Favero. As I said. Love my Assiomas.

I know it's not the ideal solution, but I got a couple of usb-c to micro usb adapters that have a secure loop so it travels around with my usb-c cables. Relatively inexpensive from Amazon and work relatively well 🙂

Great minds think alike. I do the same thing, and have added an adaptor for my Shokz headphones and my Garmin watch. I should be ready for anything!

[@keithvangastel7913]

Good to hear more competition in this space. Have you heard any indication that Garmin or Favero will be offering Crank Brothers Mallet style?

[@MacNeilR]

For MTB pedals, the engineering around maximizing bearing life and the serviceability of the bearings is quite important. I'd love to see this in the comparison video you're thinking of doing. For example Eggbeater pedals suffer from a very short lifespan when compared to Shimano pedals and so I wonder what this looks like for power meter MTB pedals... As always a big thumbs up and thanks to you and your family for all of the work you put into these reviews!

[@reid3737]

Check out PeakTorque, he just put out a video on them. He's done some analysis on this and has been riding these pedals for a while now and he seems very pleased which seems like a high bar for him.

[@ericmagee9054]

100% agreed. I used to be a CB Eggbeater guy (for a loooonng time) until I finally had enough of replacing them every 2 years. Finally switched the shimano XTR pedals 3 years ago and those babies are still going strong even though I beat the sh*t out of them on a regular basis due to where I ride and probably my riding style lol. Would hate to invest even this much money in power meter pedals only to see them break after 2 years or less…

[@MacNeilR]

@@ericmagee9054 I'm of the same opinion of XTR. I saw the PeakTorque video, and the engineering seems to promote longevity. Perhaps these new pedals are finally something to try out.

[@ericmagee9054]

@@MacNeilR I started to watch the video but he was on a cx or gravel bike from what I saw so I turned it off after a min. Is the video worth watching would you say?

[@MacNeilR]

@@ericmagee9054 It's the most in depth from a mechanical point of view that I could find so far. He said he used them on his MTB and on his Enduro bike (though pedals are not rated for Enduro) over the year he had them to test. I thought it was worth viewing, but you could skip the last half as that mainly covers the power meter accuracy which we've already seen in DCR's video is great.

[@BrianRPaterson]

Excellent! I've been looking for an SPD pedal based power meter, but some of the poor reports on the Garmin Rally XCs put me off. If these are as good as Favero's road models, they might be ideal for me. Cheers

[@jimpeyton1459]

Thanks as always Ray. Read the full report before watching.... I've has the Assioma Duo for several years...long enough to actually have the recharge ability decay 😮. Favero support is amazing. These MX pedals are a welcome addition for gravel, bike packing, etc. - wherever SPD pedals/shoes just make sense. Your testing shows that Favero has offered accuracy on par with the Assioma Duo (I am still digesting the written report. wow!). Do you think Favero will retrofit the internal spindle design to their Look pedals? My only other comment is that other head unit manufacturers should buy into ride dynamics data. I pinged Wahoo several times and got no answer. Be well.

[@mvp_kryptonite]

Excellent Ray. The technology is coming on so good for these pedals now. Shimano have no excuse lol

[@maxdaumiller9466]

Hi Ray, thanks for the review. Do you think the Assioma DUO get the PCO Feature too or is this feature hardware related? Best Max

[@aerobrain2001]

It’s hardware related as the strain gauge placement means it won’t measure the relevant data.

[@lorenzgasztner4662]

Probably buying them but still waiting for that comparison video.

[@Greenteac]

Finally some alternative to the much more expensive Garmin Rally!

[@fa1coner]

Thanks Ray for another great review! Any idea how the accuracy of these would be when using pedal extenders? I have to use 16mm pedal extenders on my gravel bike as I wear a size 16 shoe and my heels rub on the chainstays unless I use the extenders.

[@lorenzoconcina7132]

Hello Ray! thanks for the video, great content! I am interested in your opinion on having just this pedals for both a gravel and a road bike - on the former I am sure it works I am a bit unsure at length on having SPD for a road bike! thanks for the advise!

[@Bomelinn]

Got my dual sided pedals today. They work fine, setup was easy and they seem high quality. They are boxy compared to XTR, definitely going to take some hard hits.

[@kellymorris10342]

As someone who's wanting to get into power meter data for training, this is what I need. Hopefully thet make a type C charger just for the fact that one cable can do it all.

[@PixelUser]

Recieved them today

[@JulianAndresKlode]

Now they just need to release the Assioma Pro Keo refresh 😊

[@gillty]

Hey Ray, Two Questions: 1. What’s the Q-Factor? (I actually fit better the Duo-shi with SPD mod) 2. Do we think Duo-shi and Duo will get firmware updates to keep parity feature wise with cycling dynamics?

[@fukawitribe]

1. Q-factor is 53mm apparently; i'm in the same boat as you, so that's slightly disappointing (especially as i'm currently looking to change pedal/PM...)

[@diegodursi]

Thanks!! A new garmin rally is around the corner?

[@BananaChipzzz]

Hopefully, as the existing ones are garbage squeaky crap. Practically zero reason to buy them over these new Favero’s. especially given the price.

[@kodiakrider7612]

When available in the US? A couple months still?

[@cybl337]

Would be great if they were actually purchasable - atm there is just a placeholder listing of said product on Favero's online shop stating "available in around 2 months" - oof 😔

[@RetroracerDB1]

Bicycle industry motto: “If we’ve got it, it’s in stock”. A great pedal for next year.

[@A1eX596]

Great video, are there any rumours of an update to the road favero power meter?

[@darrenhill8503]

You touched on the pedal body changing tool. Is the Spindle compatible with Time ATAC Pedal Bodies? Any guidance on this would be greatly appreciated. Great content as always.

[@Dcrainmaker]

No, just these bodies.

[@darrenhill8503]

It’s shame that they are not compatible with Time Pedals as i need to use Time for the lateral float due to on going pain in their connecting tissue of my knees post full knee replacements. Thank you for your prompt reply.

[@bernardrenier981]

One comment on the pedal body (favero 49€ vs garmin 200€) - on Garmin there is a design issue so you can't change the body bearings, and when it starts creacking after 8-10 months, you can rely only on warranty to change the pedals, and after warranty you have to buy bodies...Hope Favero allows to change bearing of bodies - but if it is replacement at least the price is more reasonable...

[@michwoz]

Small Favero mops the floor with big names again. Looking at you Garmin and SRM with your insane prices.

[@PierreAlainMaire]

Great review, great product ! Don't forget that the USB mini port is less brittle than the USB-C, it may be an engineering decision 😛

[@Xhadp]

500 USD is a much more reasonable price point than the absurd 700 USD Garmin is asking for their baseline XC100 which almost no one carries to begin with. From that point alone makes this a very good product release.

[@Catcrumbs]

I'm assuming the Garmin Rally XC pedals are intended for XC only, as the name suggests. What about the Faveros? Are they limited to XC too or are they suitable enduro and DH too?

[@derx6666]

Oh darn... How I'm gonna explain this again to the wife? :) I've always said I don't really care about the power numbers on my gravel bike in Fall and Winter, but in my heart I do care. I have a lefty 4iiii on there now, but these puppies are calling out to me. I love my Assioma duo's on my roadbike, and these would be a nice to have... Ah well, probably suffer a few days on the couch, as forgiveness works better for this than permission 😉

[@AliKashoma]

Do it😂

[@frankdelatank8454]

Can you include stack height comparisons to m540, XT and XTR pedals as well? Would be helpful for fitting purposes.

[@JulianKent]

Peak Torque said 2mm difference to the XTR

[@user-pg8hz2uk5e]

When will these be available to purchase? Seem to be out of stock even on Faveros website

[@iaina3251]

Great pedals, look really good and would love these, but oof - that price and micro usb as well!.

[@scottishscrutineer]

An affordable alternative to Garmin Rally PM, just as I was considering purchasing a set of RC100 🙂. Favero just need to get stock available for sale

[@Dexxyh]

Very cool. I'm tempted, but how well does that charging port hold up over time? I currently use my rallys for cyclocross, so the pedals would get a lot of abuse, water, sand, thick mud..

[@Dcrainmaker]

We haven't seen any issues using that same port on the road side after I think like 7 years now. So, no real concerns there (and people have been using them conveted to SPD for MTB for at least 3-4 years).

[@davet003.5]

I have been running the old Assimos with Xpedo M-Force 8 SPD pedal bodies since the pandemic in gravel and BC mud. The pods are a bit bashed from pedal strikes but no charging or any other issues. They just work. Even in last year’s Unbound mudfest. 100% support Assimos.

[@CWBmtb]

One thing nobody talked about these is the fact that every pedal I have used ends up with some wear on the spindle at some point. So I would like to know how durable these are since it's the most expensive part of the pedal. Open one up for us

[@roilev]

The stack height is stated at 11.2mm. XTR are 15.1. But Favero spindle looks much thicker. Ray, can you please measure the height of the spindle?

[@roilev]

Shane actually measured it. It is 11.2 but half of the height, from the center to the pad (spindle radius). Shimano state end-to-end height, spindle diameter (and I measured it). So it would be 22.4 vs 15.1 - XTRs are definitely lower.

[@DomnuDracu]

Single or dual? Biking for fun + glimpse

[@RXP91]

Wish we'd get some reasonably priced flat power meter pedals. I hate riding clipless

[@mexicansuperkiller]

Micro usb 🤦 rocking the old school vibe.

[@belZaah]

I did not even know these charging plugs came off until like 3 years into owning the Assioma Duos. And I’d still be fine them being permanently connected. So the micro-usb is a strategic questionmark, but hardly an operational issue

[@KerenWang]

I disagree. It's cheaper this way for the company and for the consumer. If the cable gets bend, frays, etc, which cheap usb cables tend to do, you can easily replace it for 1 USD. If you had to buy an entire cable with propriety plug, it's going to cost probably 19.99 and you have to bet that Assioma makes the same plug in 4-5 years.

[@belst_]

@@KerenWang I think the issue is more with micro usb instead of usb-c. Since almost everything is usb-c nowdays, having to carry around another cable is annoying

[@michaljodlowski5746]

I never realized before after 2 years of use... Never too late to learn i guess

[@jcbusque]

Hi Ray, do you expect a release of a pods free version on the road pedals?

[@Dcrainmaker]

I think it's clear this is their new spindle design going forward. But whether or not that ends up being exactly compatible with a new pair of road bodies remains to be seen (just like how the base Assioma Duo's weren't compatible with the Shimano pedal version).

[@jcbusque]

Thanks Ray. Appreciated the answer!

[@sanjaynayyar]

Is there any way is get a larger Q factor? I run +8mm spd pedals now.

[@roadcyclist1]

Can i use look cleats with this??

[@erikmiller7166]

Ray, can you buy a road pedal body for these spindles?

[@Dcrainmaker]

Not at this point, no.

[@robd003]

What happens when the rechargeable battery dies? Can you replace it or are you out $750?

[@cracked229]

That's nothing to worry about. Will last about 25,000 hours before losing up to 20% of initial battery life. If you train 1000 hours per year, that's 25 years.

[@Dazdigo]

265 lbs weight limit for the rider. That is great. Garmin's weight limit is 230 lbs.

[@AutoxVideo]

Got mine yesterday, so excited. Unfortunately not working, connects but reads zero for power. I tried switching to single sided mode and it works fine, so maybe a bad right pedal Anyone else?

[@Dcrainmaker]

Did you activate it in the app? Else, no power.

[@AutoxVideo]

Yes, followed the setup wizard 100%, it works when I switch it to single sided, but reads zero in dual sided (I. e. it's connected and reading zero watts, and not that it's not connected and reading nothing at all)

[@Dcrainmaker]

@@AutoxVideoHmm, Assuming crank length is good, you might try putting it into travel mode and back out (use charger to get back out). That’s basically the variant of a full reboot. Otherwise, shoot a note to Favero support, so they can get you sorted first thing in the morning.

[@AutoxVideo]

@@Dcrainmaker Thanks for the suggestions, still working with support and no real progress. It appears to be either a sick right pedal or some device conflict. Will update with the resolution whenever that is.

[@AutoxVideo]

Well, if anyone's still reading this - after ~3 weeks of back and forth, the issue seems to be buggy BT. The solution is to use ANT+ **AND** put the pedals into single sided mode even though they are double sided.

[@jeffeversole291]

I'd like to have these for my MTB but I'm concerned they wouldnt survive the rocky terrain and multiple pedal strikes.

[@cybl337]

So he doesn't want to "have to re-do the planned comparison video right away because something changes" 🤔 What short term change is he hinting towards across the different models he might be comparing? 🔮

[@belst_]

Probably another pedal release

[@j0lynch]

a road pedal spindle option? I didnt hear any talk about such comparison with garmin rally (road/mtb) in the video, except for the price of a replacing the pedal spindle. I'm a garmin rally owner and if favero do release this, hopefully it will force garmin to reduce their ridiculously priced pedal spindles from 250 euro down to the 100 (50 each) level of the favero.

Honest question: as a recreational cyclist, why would I want a power meter?

[@COMOMTB]

You wouldn’t. Power is only useful if you are following a “power based” training plan through a coach or something like TrainerRoad. These training programs use power for your training plan and build future workouts based on your power

[@rattila13]

I had a pair of Assiomas in the past and I've had a bunch of power meters berfore and since. The thing they all share is that sooner or later you will have issues with them, and there are big differences in how these companies deal with them. My Assiomas had an issue from day one and it took me five months to convince them to replace it, while I got a replacement set in two days after I called Garmin because my Rally pedals never came back alive after it prompted me to replace the batteries. I really want to like these new mtb pedals, I just don't trust the company. I would give it another try if they had a North American distributor for sure.

​@@quincywalker4441Yup, I'm pretty sure we all have 15 micro usb's lying around, so I don't mind it. It's not as fast, but for a small pedal battery it doesn't matter

[@jhoff80]

@@sgriff5692 so my top scenario that this is an issue is travel. To travel with the assiomas you need to put them into travel mode or else the accelerometer keeps them on the whole time. And then the only way to turn them back on is to plug them into power. And these pedals are literally my only device on microUSB, so I'm needing to make sure I have separate additional cables just for the pedals, and a specific charger with a USB-A output. If it was usb-C I could get rid of another charger and just keep the magnetic things in my bag.
