Assioma PRO MX Power Meter // Best Bike Tech of 2024

[@stefanivanov8587]

I bought my Assioma PRO MX-2 because of your video instead of the Garmin Rally xc200. I still think it's my best decision so far. You saved me money while I got a better product. Thank you for your videos and hard work so we can make good decisions at the end of the day.

[@gplama]

Awesome! Thanks for the feedback. 👊🏼

[@garycasperson4106]

Bought them based on your review and a couple of other reviews. Took up gravel racing as a retirement project and used the pedals both on my 2024 Giant Revolt Advance 0 and my 20-year old Trek 2300 road bike. Performed flawlessly over about 3,000 km of riding in various conditions, including Belgian Waffle Ride B.C. in September. As a consequence of my project, lost weight and reduced my resting heart rate by about 10 bpm.

[@DuckRideDuck]

The Duos are so good, battery lasts for ages, no drop outs, great power info…. what’s not to like, oh Look cleats!! I can live with that!! Cheers Lama, for all your content this year 🎉

[@powermetercity]

We’re glad what we’ve seen matches up with your experience! These have been one of our favorite power meters this year and we’re stoked to hear your feedback mirrors our customers’.

[@andretheys8487]

I’ve had the Duo’s on both my road bikes now going on 3 years, love them, no issues, so when I got back into MTB I put the MX Pro Uno on my MTB build, running them since June 2024, no issue, love it and it just works, also the clip in and clip out all works… Cape Town, South Africa

[@thijssluijter7753]

Put them on the bike and never gave them another thought. Absolutely flawless

[@tbone-ip5fi]

They have the in-spindle electronics.. when is coming to the road pedals. As has been said by many before, when they release a power meter for Shimano SPD-SL cleats with in-spindle electronics, they will basically own the market.

[@CoreProject05]

love them. Solid, consistent. No issues, no calibration problems, drifts anything. I've tested them many times for weeks, spot on with neo 2T and, 1.5% difference with both of my power2max NG Eco-s (calibrated to +-1% in factory). Scaled down the p2m. All devices spot on, consistent.

[@flippflipp1024]

My Pro MX 2 also spot on with my Neo 2t

[@SignorLuigi]

Nice video! 👏👏👏 I have the Assioma Duo Shis and have been disappointed by the lack of durability of the sleeve bearing design used in that model. So I hope Assioma is working their tails off, perfecting and bringing to market a version of the Pro MX for SPD SL pedals. 🤞🤞🤞

[@derx6666]

Don't have the Pro MX, but still use my 3.5 year old Assioma Duo. Recently did a lab test with my own bike on a calibrated cyclo something trainer, and the guy running the test told me the numbers he saw from the Favero pedals were spot on everytime he saw them on a bike, as were mine. Constantly within +/- 1% across all power levels, from easy 130w to 345w vo2 (for me) and during a 960w avg for 20s sprint with a peak of nearly 1150w. My 3.5yo pedals holding up great. Battery life is still like new. Only thing I wish for is that Favero releases the Pro MX-2 with a road pedal body. It'd be an instant buy from me.

[@ryoukokonpaku1575]

Hopefully also SPD-SL compatible. Personally prefer it than look pedals imo. With the new spindle from MX, it should be possible without any Q-Factor changes since there's no pod.

[@jeremymcbride8729]

I was on the list to get them as soon as they were released. Apart from my Scott Spark 900 Tuned, these have been the greatest purchase I’ve made, in relation to my MTBing. Amazing bits of kit and so much data. Thanks for the great work Shane! Merry Christmas mate.

[@ShawnIsBatman]

I own both the MX-2 (gravel) and the Assioma Duo (road). I can confidently say that I cannot foresee me ever using any other power meter than a Favero product. Absolutely rock-solid in every respect.

[@andywalford7544]

Assioma Uno on my road bike, MX1 on the gravel. The Unos are about 5 years old now, couple of bearing replacements is about it, probably 30,000 km or so in that time. Power numbers still apparently unchanged( as is my overall fitness basically unchanged over that period). The MX1s I have had since release, zero issues although they don’t seem quite as secure as the previous Shimano SPD pedals, mostly in the sense of seemingly more float, zero accidental releases. Power numbers match the road pedals so far as I can see. Love ‘em both!

[@MattandSharonOutdoors]

Great peddles!! bought them after watching your review and havent been disappointed. Keep up the great work and Happy Holidays

[@PatSheerin]

Very happy with my pair. Have worked without issue

[@stompenem]

I have been using my Pro MX 2 pedals all year without any problem. I just updated the firmware- thanks for the prompt.

[@madrx2]

I love my Pro Mx2's, I just wish they had a Type C usb on the charge cables.

[@kiverrussell8369]

Great to know Favero have another winning option for MB and gravel. Have loved my Assioma Duos, which are just beginning to creak finally after 3 and a half years of being faultless - left pedal intermittently reading high/low showing as ridiculous imbalance suddenly but probably related to a badly needed bearing replacement that I have had the spares for but hadn't got round to 🤞

[@stephenbetley9596]

Now, lets hope the Assioma Pro RD will be on the best bike bits of 2025. Come on Favero get your act together.

[@kidsafe]

That subtle Elemnt Ace and Coros Dura burn.

[@gplama]

It’s been a l o n g year… the pain of the Dura still lingers.

[@chrisridesbicycles]

I can only agree. Flawless performance all year. Great battery life, I had them on for a 3 week trip and did not have to recharge. The only downside I can think of is Micro-USB instead of USB-C and the adapter being easy to loose (what I managed to do)

[@jimpeyton1459]

Assioma is a great company

[@ojtamno]

I have MX-1. Awesome stuff. Got 2 rides with it in heavy rain, once it went totally under water. The only issue after all that was some squeaking noise which turned out to come from that red plastic ring around the axle, one which marks the power pedal (same ring is black on non-power one). I made service on that pedal and inside it was all OK. Originally I had some up to 8% difference between that pedal and my tacx neo, but after more tests it turned out it's asymmetry in my legs which, for some reasons, becomes bigger when riding low watts (around 100W). On higher powers, the difference is

[@Longo78]

My MX-2s going strong after two months. Our trails in Townsville are very rocky and pedal strikes are common - haven’t killed them yet 😎 Am about to travel OS and wondering if I pack these pedals and keep Zwifting in hotel gyms while I’m away. Thoughts?

[@joostw-69]

I bought the Duos in Oct and they perform outstanding. Only issue I had was with my wintershoes, due to placement of the cleats. That was the fault of the cleats not the pedals.

[@kovar2344]

Thinking about buying Ass-ioma (lol) for my my bikes. And also so my dad can finally try riding with a power meter.

[@BlackgoldTwinduck]

i do hope there will be soon a podless Assioma SPD-SL

[@Denisbled]

I have them on my gravel bike Scott addict 10 which I ride predominantly on road with slick 32mm on it. I live in the mountain region so I do ride here and there off road.. bottom line - pedals are rock solid!

[@paulbyrne4214]

Shane I bit the bullet and bought the assiomas after watching a range of vids and yours in particular. Yes they are expensive BUT I’ve been using Zwift and a Kickr core to drop weight (35kgs to date) and knowing my Zones was key to burning fat not carbs- so I bought them for my roadie. Love them!!!! Now I treated myself to a steel gravel bike- only question is do I swap them over or spend another small fortune so I have them in my gravel bike? I like idea that I can track effort and slow down to keep energy stores. Thanks again your impartial and evidence based reviews. Anyone ummming and ahhing- these are very useful and accurate

[@gplama]

Mate! Amazing. Dropping 35kgs is one hell of an achievement. There’s no price you can put on that I’m sure. Treat yourself and spend the money on equipment you’ll enjoy using. 👊🏼

[@UUche]

Got the Pro MX Power one sided because I wasn’t sure how well it worked, It is a bit on the heavy side for my gravel bike, but It’s the most accurate and in-depth power meter that I have ever used coming from a 4iiii power meter background.

[@ScottMoore_xco]

I have the Pro MX-2s and they are great pedals. I have however shifted them to my backup gravel bike as I have found clip in with them is slightly more difficult than an XTR pedal. Maybe it is me and muscle memory though it is very noticeable that they do not clip in as well for me compared to the XTR pedals. I also have the Duo SHIs on my primary road bike and these are fantastic. Not trying to bash Favero as they are doing a lot of awesome here, though wish the clip in engagement paralleled the XTRs.

[@mychannelforfun5523]

I have the pro MX 2 pedals and they are great.

[@shannonparker7404]

Love my PRO MX. I honestly wonder why we bother with SPD-SL. My DUO's now collect dust in the shed. Maybe I should sell them.

[@samgrice66]

Happy new year Shane! Please do a trouble shooting vid for Zwift click! For the life of me I can't get it to work!😡

[@JosephDowski]

Just received my MX-2's. I will be charging/calibrating/installing later today. My one concern which I just learned from the manual, I use the Shimano Multi-Release style cleats because I have a neurological foot-drop condition where I can only unclip my right foot by turning in with my foot, rather than out like normal. The manual states outward release only? Hoping the Multi-Release cleats are compatible...

[@pizzathehut2001]

I find them flawless, get on better with the lighter unclipp, than the, in my case unreliable assoma duo, on my third right pedal, so still using my much loved P1s

[@gplama]

P1, damn. The OG nuggets! I left a set on the shelf with batteries in them unused and they leaked, RIP P1.

[@kiverrussell8369]

Is PCO coming to the Assioma Duos finally too?

[@gplama]

I haven’t heard anything there. I hope we’ll see road versions of the PRO soon, in both Look and SPD-SL pedal options.

[@kiverrussell8369]

@@gplama thanks. If it turns out my current left pedal high/low issues with the Duo's isn't fixed with a bearing replacement I may hang on for the MX road version. SPD would be good...

[@kidsafe]

@@kiverrussell8369 PCO would be hard to implement on the road pedals since the strain gauges are at the base of the spindle instead of the middle.

[@fotmheki]

Using them last 10 months but less then you and with less watts 😂they are still pretty good, I had no issues. Btw I also have my PCO of the left foot +8 mm while the right foot is dead on 0 mm (avg both)

[@aronanlife9039]

Love the assiomas! Both them on your feedback. In addition I'm Looking at getting a replacement head unit in the new year - one of the things i'm wondering are the Garmin Head unit the only ones to show cycling dynamics type display (i know its a Garmin solution) - is there an alternative on the horizon?

[@gplama]

I believe Bryton do Cycling Dynamics too. I haven’t seen it in action though.

[@aronanlife9039]

@@gplama cheers for that - i'll have a look that direction

[@Elbrunosh]

Hey GPlama, can the sensor also be converted with the duo cleats? I love the cleaner look and the possible decreased Q-factor.

[@gplama]

There isn’t any compatibility with road pedal bodies for the PRO spindles…. yet.

[@oatmonster]

Surprised they havent released a version for road cleats using the same spindle yet. Seems like a no-brainer

[@stephenbetley9596]

As an aside, you mention the Favero Assioma firmware updates. Anybody having issue with this update just not working? The android app has got some slating in the past for not working. Tried 4 different android devices on 4 different android versions with fully charged up pedals. Connects fine and can change settings and calibrate, but the firmware update always fails in the final update process on the left pedal. Logged it with Favero, just wondering if I'm alone in this?

[@stephenbetley9596]

Update: Favero pushed a new version out 23/12 which seems to have sorted the issue on Android. Updated Ok. Good work.

[@grobbosixtyone]

My mate has them on one of his bikes. He has a Quark DUB crank based PM on his other bike. The Assiomas both keep failing to be located by his Edge 810 and 1030 head units. These two head units also have his Quark DUB power meter sensors paired to the units. Is this causing the issue?

[@gplama]

Yes. You can only have one power sensor paired at a time.

[@grobbosixtyone]

⁠@@gplamaSo he needs to disable the SRAM PM sensor on his head unit when he’s on the bike with the Assiomas ? And vice versa when he’s on the bike with the Quark PM if he wants to keep switching the head units between bikes?

[@gplama]

It will pair to the power meter that is awake, so not moving the other bike is a quick tip.

[@grobbosixtyone]

@@gplamaThe other bike isn’t moving so the PM should be asleep but I’ll get him to try disabling it anyway. Thanks again for the quick response. Merry Xmas to you, Von and Max

[@enotracoon9244]

MX seems to translate lower power data compared to road Duos . Based on feeling , no any tests made

[@gplama]

Time for testing! 👌🏼

[@BarePotato]

Look like people enjoy PRO MX so I might be an outlier having real bad experience with it. (have to note Assioma support was quite helpful) I find it just an inferior as a pedal compared to normal XTR. Binding tension felt way weak so I clip out straight up by VO2 efforts multiple times on both legs (probably 400-500w for 4min 5times) The worst part was.. when I keep tightening the binding tension, the spring snapped. Assioma support was quite helpful diagnosing the issue but since I bought from local distributor who was bit condescending, I just decided stop using it. I had no issue with normal XTR and Quarq combination so for me it was definitely no go. The only silly reason I tried it is because I wanted to use 43/30 SRAM chainring which isn't compatible with Quarq.

[@gplama]

Huge watts! What shoes are you using?

Check cleats. Check shoes. Assess the interface between them. If you’re waxing your chain then put a dab of drip wax on the pedal where it interfaces with your shoe.

Not a lot apparently. I think you’re the first to ask. Given their track record for questionable accuracy and poor ERG performance, I wouldn’t be putting any money down on one unless I knew for sure (and not just from an advertorial review) that it works extremely well.

[@heinzholger8321]

Has the minimal bearing play become worse over time?

[@gplama]

No change. I do keep things tidy af though. Waxed chain, bike cleaned regularly. I’d be keen to hear if anyone else has put them through hell and noticed anything different.

[@BarePotato]

I believe Assioma does mention the needle bearing is supposed to have little play. It's probably nothing but for those who care it feels bad.

[@marcelchaloupka]

I bought there pedals. I bought directly from Favero but the shipping company they used over charged me on import costs an issue I’m still dealing with. Favero is uninterested in the fact that the shipping company is gouging their customers so not particularly happy with Favero I’m getting a significantly higher power reading compared to my old Stages so initially I wasn’t sure if it was reading right but i think that they are most probably giving the correct reading. I like the cycling dynamics data, very useful but what is slightly annoying is every time I go for a ride is get hit with having to do a recalibration. I find them hard to clip into compared to my shimano mountain bike pedals. It’s interest that the mag charger is using a mini-USB instead of USB-C. Considering the EU made such a big deal over Apple not using USB-C and insisting that everything should be standardised around USB-C I’m surprised that Favero is using a non-compliant connection. If they update their road pedals to the same style with the power metre in the spindle, I’ll most probably get those but will buy locally. My biggest concern is battery life and the lack of serviceability on replacing dead batteries it time will tell if these become expensive toys in the rubbish bin because of dead batteries

[@gplama]

You’re likely referring to import taxes. Those are thanks to your government, not Favero or the shipping company.
