Don't treat it gently - I review The New Favero Assioma PRO MX Power Meter 

😂 all you tech geeks who follow this channel I’m not so sure. Been riding these for a whole year now and no one noticed. I thought better of you all.

@@PeakTorque 4K screen too. Inexcusable.

Nah. Proper cyclist haha.

Especially when you consider that he weighs approximately 970 pounds.

@@grahamwynde1176 did you mean to post at top level?

Dunno, I'd maybe buy the Rally if they were half the price of the Favero. Maybe.

@@JulianKentthose Rallies are huge AF

There was never a reason. Favero Assioma Shimanos work with Shimano SPD bodies.

@@Spartan9567 do you mean you can swap a pedal body on these? I want to put a flat/SPD combo body on a power meter for casual touring, commuting and the city. Any hints on a howto on youtube?

Cheers

Glad to help! A year of battering and no issues.

@@PeakTorque I'd be putting them through a similar thrashing. New England winter riding looks about as bad as England winter riding!

I knew someone would help, I’ll try that. Still learning, I’m very beginner level. Prefer nuts and bolts! 🎉

go ride your bike! ;)

hahh, yes, the BePro is overmeasured the power with 5-15% by default (due to the very poor factory slope calibration), and because lack of auto-angle monitoring, if the axle is rotating a bit, the installing angle is changing (which is needed to the power calculation), but it remained on the old value, the whole power calculation was off (you had to reverse pedaling, that set the new angle value, but it could rotate a tiny bit day by day... so the best was to do this reverse pedaling everyday , or throw out the pedals). in the Assioma the better slope calibration and the auto-angle monitoring help "lightyears" in POV of power accuracy.

True. But am I blind or do they look 100% like the SRM pedals?!

Same. I’m basically an unpaid Favero salesman now.

I'm just going to say this: I have the Garmins and they are ok as power meters but awful as pedals. They squeak unless they are completely covered in grease. They are loose, no matter how much you tighten the tension on the cleats. I have had 2 replacements and they still squeak. Garmin makes absolutely terrible SPD pedal bodies. I will be buying assiomas as soon as they are available where I live.

@@nssomething8370 Sounds like I have dodged a large calibre bullet. I'll keep an eye open for the new Assioma MXs. Cheers

@@BrianRPaterson Absolutely. I'm not going to lie, I still use the Garmins and like the power meter aspect, but they just suck as pedals. I got them in 2021, so I did get a lot out of them up to now, but I won't shed any tears when I dump them.

Update: according to the website they will only be available in "around 2 months". Maybe should have extended that review embargo.

Meow! Go tell them

Name the channels if you're going to put that out there Bazza.

Found the machinist hehe. A2 is about the hardest I've milled, was slow, but worked on an old beat up haas

It’s an X3 camera on a carbon pole. Still very flexy. Got a much stiffer support for the next one where I’m mounting a brace on the fork crown mudguard mount!

@@PeakTorque I did wonder if it wasn't mounted to the fork

Blindfolded, could not tell the difference between this and shimano. Like I said in another comment at first I found the default tensions a bit low on mx but on this final version it seems higher and the exact same as XT. I may have been wrong though - it may have been the same all along.

Today I believe, that’s when I was asked to keep the video hidden until… if they’re not available I guess someone has f4cked up 😂

Sold out!

If they're available, they're bound to go to pro teams first! They'll have several on the open market to satisfy UCI rules. Sold out.

They’re all double sided! Both side power meter. The mx1 is power meter on one pedal only

Nobody seems to know anything about this source of error

No

Quarqs usually overreads :) (but could be single other cases..) but if you can do an accurate static weight test at home, you can get it more accurate. the problem is the old and dumb strain gauge in it, the Assioma and P2M NG, or maybe any newer chinese miracle have much newer and smarter strain gauge with active temp compensation, the Quarq is similar tech as the old Power2Max TypeS, more then 10-15 years old... if You can simulate a very big temp change near to the bike, you can compare these powermeters' behaviour, i made a few tests few years ago on winter indoor, the results were very spectacular. if the temp is constant or just tiny changes, almost all powermeters are measuring on acceptable level or "good"

Correct its a 15mm wrench. I never used a torque wrench, just did up reasonably tight. No problems in 12 months, constantly swapping bikes.

when i bought the Garmin Vector 1 in 2013 sept, i had to buy a torque wrench (Holex) and a 15mm wrench adapter, i had to make this thinner with milling machine with a few mms because lack of space. but the ParkTools made a cheap and narrow-headed version (TW-1) but there was a world-wide shortage then, probably due to the Vectors :D Luckily i dont have the Vectors since many years, i have just more Power2Max NGs , but the torque wrench is good for the normal pedals and for the Rotor cranks (with allen/hex adapters)

You use a crows-foot adaptor. When the original Vector 1 came out the retailers of 15mm crows foot adaptors sold out throughout the country for a few months. Eventually Garmin started including them with the pedals. For Vector 1&2 the correct tightening torque was important to the accuracy of the product. When we start selling Assioma Pro MX we will offer a crows foot adaptor as an option with the product if people want to make sure they are tightening them to specification.The recommended tightening torque of 30-40Nm is probably harder than most people do their pedals normally.

@@roberttobin7342 its name "open jaw plug-in head" what i bought , the crow-foot a bit different , but yes, the proper tightening is more important than sometimes the people thinks.

Thanks for The answers, guys 🤗

Assioma is very hard to fault

Try Lake? I have shoe problems, found a pair that fit very comfortably (didn’t buy bec $$$)

L/r R balance pretty much anything. Full cycling dynamics (pedal phase, torque eff etc) only from Edge 520 plus onwards

No. It was a horror crash. The bindings are almost identical to XT in the way they clip and release. If you were blindfolded you couldn’t tell the difference. In the early days I would almost say the default tension (without adjusting the screw) was lower on the mx than XT but whether they have updated that or not I’m not sure but on the latest set they feel absolutely identical.

@@PeakTorquetry SH-56 Multi-directional release cleats from Shimano?

@@e.con0210 nah i like being connected. They would scare me!

@@e.con0210 I never understood why SH-56's even exist. To me they are dangerous AF, since you're not in full control of when they disconnect and when they disconnect suddenly, e.g. when you bunny hop, you're not going to connect back straight away - basically losing control on the disconnected side (or sides if you're unlucky and both unclip). It's like having a flat pedal but worse.

That's what they claim. Might make it less. Doesn't make a re performance difference though, otherwise the WT would be on it. It's a preference thing - your leg/brain adjusts accordingly

yes, the Assioma and the Power2Max NG are using IAV, so they measure the same with round and oval chainrings. the other powermeters are on the market not, 3-4% higher measurement with ovals (Osym) or if You have very kicking pedaling technique instead of "perfect" circle pedaling , then also these "cheap toys" are overmeasuring the power.

​@@andraslukoviczki519 Why is power overestimated if non-round chainrings give a more uniform angular velocity?

"power meters assume that you turn the pedals at steady speed throughout each pedal stroke revolution. The problem is, oval chainrings cause your crank velocity to change during each pedal stroke, as they limit the time in the dead spot and lengthen the time in the power phase" in short. btw i suggest everybody to learn to pedal smooth and fluently in circle with round rings, this oval is just hiding your problem, but not solving it. it has no power gain , otherwise everybody in the pro peloton would use it... but as we know, especially in cycling industry , if you do a good marketing, you can sell anything worthless for high price also 😂

If your legs are even power distribution, get the single!

@@PeakTorque needs to be even power distribution across the range. My L/R balance for a ride is usually in the range 49/51 to 51/49, but zone 2 it is around 47/53 and above threshold 53/47 (10mm leg length difference, quads and glutes engage differently accord to physio). So using a single sided pedal meter would be as reliable as a Shimano power meter for me +/-5%

@@PeakTorque I realise it's an impossible question, but does the leg power distribution thing matter in the real world for the average rider?

I’ve done tests on double vs single sided powermeters before and believe it or not your legs fatigue at different rates which is important and the reason why single sided powermeters can be misleading. Not as simple as it seems

@@FlourescentPotatoaverage rider doesn’t really need power meter, having said that Im a below average rider but really like knowing this stuff and would totally geek out on dual, under $800 for both vs $500 for single. It comes down to how much you want to spend for the info (whether or not it helps you maybe become a better rider)

Are you using new shimano cleats? Mine feel the exact same as xt, although i tightened the tensions spring a little vs xt, as the release tension felt lower. I’ve had mine for 1.5yrs now, was an original tester.

@@PeakTorque I haven't put new cleats on yet. With xt pedal on on side and pro mx the other there's definately a good difference. Made more obvious with big feet clipping the chainstays.

No. Absolutely not.

@@PeakTorque Assuming the shoe tread interfaces with the pedal body correctly, sure. But that's not guaranteed at all and it's a lucky dip depending on which shoe you use. When the tread wears, it no longer makes contact, the efficiency drops and the contact gets sloppier and sloppier. Fine for MTB but horrendous for road and fast gravel.

Get stiffer shoes with longer tread then?

@@JulianKent it’s a crap design. great for mud clearance and ease of clip in/out, terrible otherwise. also the float is way too much, very sloppy

@@thedownunderverse do you have data to back your claims and how much of a "loss" are we talking about? Something that would bother world tour riders during TDF, i.e. 1.5 sec over 4 hours? GCN or any other youtube grifter's "opinion" doesn't count as scientific facts.

You could market them as having integrated foot warmers.

@@andrewcockburn7484 well played! Literally, ☢️ nuclear powered pedals.

Wow, thank you!

Titus Fireline (Planet X) beautiful frame

Thanks@@PeakTorque, I have a Titanium roadbike made by Waltly. I am currently looking for a hardtail. I read somewehere that Planet X titanium frames are also made by Waltly.

It was supposed to be yesterday, don't know what they are up to. Probably some marketing/forecasting tactic, no idea.

@@PeakTorque they are not available on their website either.

@@PeakTorque Do you think they will bring out a Shi and Keo pedal body to upgrade to a road set up if wanted to like Garmin do.

They haven't started selling them yet and we as retailers cant take pre orders until they have enough stock to start shipping. It is going to be a few weeks at least before you can place an order or anything starts shipping (I spoke with the owner today). When Assioma launched in 2017 they were still a relatively unknown company so demand didn't overload them and they had stock (and all the spare parts) at launch point. Now they are probably the market leader in power pedals they know demand is going to be massive to start with.

Just the yoeleo stock bar/stem on the g21. I really like them.

The first person to pick up on this!

All comes down to battery life. An original SRM and PC8 head unit would go a lot faster than 1Hz but for most people battery life of PM and head unit is more important.

@@PeakTorque these power meters record faster than once per sec though, it's more about how this data is stored/probed. You can test it yourself by connecting two devices (e.g. watch and computer) and recording same session on both. You'll see that the power numbers don't match.

@@channul4887 the transmitting signals are on 4HZ or 8HZ via ANT+ but usually the powermeters are sending the SAME (internally averaged) power value during these 250ms or 125ms rate (there are a very few exceptions, but these 4 or 8x same datas are needed as redundancy for perfect signal quality, the signal interferences can ruin the transmit if you send 4 different power values within 1s and the had unit need to process all the 4 different values, there will be too much dropouts), the instant (so at the end of the ride only the max power) power values are could be a bit different if one of the head unit picks up before the value change , and the other is after the change, but the avgpower is ALWAYS THE TOTALLY SAME for a ride (if there are no dropouts , of course). If you can read the raw ANT+ signals from the powermeters , it is clearly seeing. yes, there are non-standard method to get faster data rate (honestly, higher resolutions needs only for sprinting, nothing elsewhere), even on ANT or easier to get it via BT (like the Stages has/had the 64HZ high speed mode via mobile app into csv,)

except that they allegedly were not informed upon test results prior to the video

Correct. They have been under embargo for months. I’m surprised none of you spotted them before 😂 call yourself bike tech nerds or what?!!!

I’m pretty sure they would have actually developed them properly and made sure they were confident in their own product before giving them out don’t you think? Non sarcastic version: of course they were confident and developed them properly.

@@PeakTorque Yes, that's a good thing. It's a sad that you have to emphasise this positively for the cycling industry. Remember last season when 9 Look frames were broken at the chainstays before Roubaix even started?

manufacturer's review embargo?

@@super8hell exactly that, part of the launch campaign

Not if the viewers use even the slightest bit of critical thinking, and realize that this is the embargo date. If they released their videos early they'd violate the contract that allowed them the pre-release access that they've had over the last few months in order to make the video. Without this system, you'd have no videos today, and then either unboxing or rushed first look, or else be waiting 6 more months have have this video in the fall '24 to give them time to collect the data.

@@galenkehler I'm totally OK not to have a video today, honestly, because we are not on a strict schedule anyway. But some lab tests and disassembly would have been worth a month or two more delay. Data "collected" here is worth one intense weekend tops. Getting familiar, crash, test ride. No durability claims backed up with measurements, all numbers are from the website.

It's never bothered me. I ran this one again and I can hear fine. No need for the comfy chair.

This is about degradation over time. 10% capacity loss after 600 full capacity charge cycles is pretty on-point.

I've been waiting ages for a decent SPD-style power pedal and these look pretty impressive. I don't mind waiting a few months, or longer, to get something good. Plus, it'll give some time for any less obvious faults to show up in vlogs and forums.

They haven't started selling them yet. You will have to wait for a few weeks.
