I’m on the waitlist for the uno. From what I read these are the easiest for multiple bikes

Single sided power meters assume that you always have the exact same left-right balance, regardless of fatigue and intensity. This isn't really a great assumption, it can change, and then when it does, the power inaccuracy is double the change in % balance because it doubles the power measured, which quickly can make it useless

ive heard that dual sided is better but can you expand more as to the why?

My n=1 experience with the Uno is that it extremely accurate.

I do a regular weekly 1hr ride route, weekly 2 hr ride route, and a weekly commute route, and the overall ride AP & NP power is often identical on similar efforts down to the watt. For sure, not even a single ride where I've been 'that's weird - 10 watts higher/lower?' If I +10 AP/NP, I've put up a much more significant effort so I expect it. Same with all the climbs/strava KOM routes.

I suspect the duo would be more accurate for short burst intervals, but for the long typical triathlete rides or longer intervals, the uno seems rock solid.

I was going to upgrade to the duo if needed, but seriously, I have absolutely zero reason to do so. There is no way I'm seeing variances in the range of those folks who theoretically claim it's off for longer intervals or overall ride data.

And it literally doesn't matter that I don't know!

Yeah, sure. For me for example my left/right power is not 50%/50%. Sometimes it's 45/55. When doing intervals with let's say 300W, power could be off by 15W in this case. That's quite a lot. Especially considering power distribution is not always the same. Sometimes I do have 50/50 or 52/48. In this case I'd wonder why my intervals feel harder or easier today and I'd be right because I could be 20W higher or lower than last time. And since you don't know distribution with a single sided pedal you will left wondering if you're having a good/bad day or your distribution was just different today.

Especially Assioma are a great offer, sometimes there's even a discount. I'd get the duo, no question

Not even once have i had a day where I looked at long interval power or overall power (AP or NP) and thought - wow that's weird - 5 watts higher/lower for the same effort (or more). It's literally that precise for me - down to the friggin watt (annoyingly, sometimes - wish it would go up faster!)

The days on my long ride where I get a rabbit to chase and end up riding race pace for a long stretch, yup, that shows up in the average, like +5 or even +7 to the overall power results. And when I'm feeling tired due to training load, yep, that shows up.

Bottom line, at least for me the unos don't reflect any of the wackiness that people keep throwing up on this forum, like intervals suddenly coming in +10 watts or lower.

20watt differential unexpected results is so out reality for me that it's a joke - I would have a hard time even believing a 5 watt errant differential based on my intervals at FTP where I can absolutely feel that 5 watts difference, and for sure, there's no variance bigger than that even with a uno.

I would 100% recommend getting the uno as a triathlete and being 100% fine with it resultwise - the uno itself is more precise and accurate (as assessed from my FTP+ interval work efforts) than any other measuring device I have for tri - GPS, Scosche HRM, Wahoo Kickr PM - so I'd recommend it without hesitation. This is from real-world use as a triathlete (not crit racer.)

I do have some money to burn, and when they are back in stock, I'm actually not planning to upgrade to the duo, but to get a second uno for my other bike (I currently swap).

No difference between Duo and Uno for multiple bikes. You still have to swap both pedals. Tbh, I'd always go for both sided

I was referring to these being easier to switch than other power meter pedals.

Question through, you still have to switch the right pedal on the uno? Why, I thought the left one was only active? I was going to have the same right pedal on both bikes.

I don't have the uno but I'd assume you still get two pedals. One has a powermeter and the other doesn't but same look, same weight, same feel and so on. So in order to ride with the same pedal left and right you'd have to swap both

The uno comes with one power pedal and one 'normal' pedal just for symmetry.

I am seriously considering just buying a 2nd 'normal' pedal so I can just swap one (instead of both) Uno pedals between my 2 bikes, but honestly, I have enough money now that I can just wait to get a 2nd uno.

Thanks above to the poster validating between actual real-world use of single vs duo. It proves what I've been saying all along for quite a few posts in the past - with lots of 'theoretical' disagreement including some pretty crazy 'what-if' scenarios, but from actual-real world use, those bizarro scenarios absolutely don't come into play.

I'm in the same boat as you. PITA switching pedals (waaaaa first world problems) and I'm just telling myself to go ahead and get another set

This video makes it look like a 30 second deal, any idea how accurate?

It is pretty close. They left out a few seconds on either end torquing the pedals to pop them loose and then torquing them tight on the 2nd bike. Loosening the pedals is not trivial. That takes most of the removal time, because you need to position the pedal with the wrench and get leverage. Add another minute to the video for a more accurate picture. So, 90 seconds is a conservative total swap time.

And a thread about when a power pedal will be back in stock turns into a debate about uno vs dual-sided pedals!! And the the person who started the thread still doesn't have an answer. LoL!

To add my 2 cents: when getting multiple bike fits on a computrainer, my left/right was always 49/50 so I figured why pay extra when I know my power is even to start at general aerobic effort. I really don't care if there's a discrepancy in left/right during a Sprint. Although it would be useful if I knew for hard/ above threshold efforts if there were a major left/right discrepancy, but I highly doubt there is. I've been using the 1-sided Vector 3's for two years and have no regrets.

Sorry no one answered your question!

Honestly seemed like a longshot that anyone was actually going to have an exact answer for me but figured there couldn't be any harm in asking. Happy to see people discuss the pedals in general though

Is 850 good enough for them? Like when they retail for 650 does that cost ending up being more due to being from an Italian company with shipping and everything? Because Id be willing if it was really only like 100 up on cost but 200 more than normal seems like a bit of a waste to me.

If you compare 850 for Assioma DUO vs. Garmin Vector 3 dual-sided $999.00 direct from Garmin, I guess the 171 premium (vs. Assioma retail price $679 w/ 50 day lead-time) may be worth it. For what it's worth, MyBikeShop has the Garmin Vector 3's in stock for $825.00. So it's up to you.

If it were me, I'd just place the order direct with Assioma for $679 and wait for delivery, and use RPE and/or HR for the next months and a half -- and spend the extra 171 dollars on a new Tri Kit, or buy 6 months of Gatorade Endurance and Protein Recovery. But that's just me.

Hey SnowChicken I just got an email that Clever Training Assioma Duo pedals are in stock - https://www.clevertraining.com/...-cycling-power-meter

Some people have had not-so-good experiences with them; however, I'm in the states and have ordered from them and had no issues. Seems about 80% have no issues and 20% ... well, they had some issues.

Also, you can easily get a 10% off if you just give them a new email address. I have a 10% off code if you need. Let me know if you need it and I'll PM you. But honestly Dude, the Uno sided is $414 w/ 10% of is $373 bucks!! Myself and many athletes use the Uno side and have zero issues. You're highly likely never to utilize all the metrics for the duo side, and unless you have a noticeable imbalance between left and right leg body mechanics, you really don't need the Duo. It's overkill. Just sayin' :-)
