Look Power Pedals-what are your thoughts?

Hey all, I am looking at getting some look power pedals for my race bikes. Yes, multiple bikes, because I know I have a problem lol. I currently only have one power meter on my training bike, which is a stages left hand crank power meter and I love it. I think it’s time to start using power during races, but obviously it’s way too expensive to buy a single power meter for each bike. That’s why I think the look power pedals would be the best option since I can pretty easily swap the pedals between bikes. And I don’t want to consider other brands because I have been using look pedals for years and absolutely love everything about them so don’t even try :wink: according to their site, they have three options. I just want to see what any trainer road mates think that have experience with them. Is one-sided sufficient? Do you need two sided for pedals because they are less accurate or something? And what’s the deal with the Uber expensive one? I’d love to hear your thoughts and please let me know if you have questions about my questions…

Assioma are cheaper and rock solid.


Have a look at the cycling weekly review for the Look and Assioma power pedals. Basically a no-go for the Looks, especially when switching often between bikes. Also have the Assiomas, they are great.


I will look them up tomorrow. Hadn’t heard anything bad, but I will look for it. Thanks!

Someone at my LBS said the Q factor is different between my normal looks and the Assiomas. Any idea if that’s true? The measurements on the websites look the same, but maybe there is something I’m missing?

I don’t know about the exact measurement but I had no problem switching from Shimano pedals to the Assioma. I did need one spacer to ensure there was at least 1mm from the power pod to the crank arm but, again, no problem adjusting.


Okay, so I don’t feel any closer to a decision than I was when I created this thread lol. So the guy at my shop says the asiomas have a different QFactor, but the website measurements show they are the same and I’ve heard on here that they should be the same as looks. However, I can get a copy of the wahoo pedals that come in the speed play form. The issue with that is that I would have to switch from look compatible cleats to the speed play options. That means I either need to buy a second set of shoes, or I just need to get used to switching pedals on all of my bikes all the time.
If anyone on here has any advice on specifically one of three issues, that would help. The first is whether the fit of the asiomas would be the exact same or similar to my look pedals, what the exact problems with the look power pedals are that makes them unfavorable, and if anyone has used the wahoo pedals to say whether they’re good or not.

Not that I have tried the Looks but just looking at price, the look unilateral PM is more expensive that assioma duos, which I can confirm just work


Assioma DUO are ~55mm. That’s what I’d call pretty close to a 53mm-54mm non-power pedal width.

Assioma DUO-Shi are 65mm. Not exactly close to a standard road pedal.


Also assume LBS might be thinking of the Shimano version of the assiomas.

Only potential issue with normal assiomas regarding q-factor is if your cleat position is extreme - pushing your shoes all the way inwards - then you could, possibly, get your shoes to touch the pods - but I’ve never heard anybody having issues in real life.

It might be worth the OP watchinbg your video on it (specifically 7:20 onwards) where you highlight the Q factor of the Shi and compare with the DUO

Speedplay are great pedals IMO, but the power version is very new and unproven. I’d wait before getting them, lots of companies (e.g. Garmin) have found that making a reliable, durable and accurate power meter pedal is harder than it looks and have gone through multiple iterations before getting it right (if they ever do).

My experience of owning power pedals was that 1) once I had power on my rides I wanted it on all my rides. So that meant switching pedals every time I switched bikes. Not just for power but for the features that derive from power like TSS, VO2 Max estimate, Training Status (I don’t rely on these metrics but I like to have them as an information source). And 2) switching pedals that often quite quickly becomes a PITA. In my case it was 4 different bikes (TT, trainer, nice race bike, winter/coffee ride/beater bike) involving 3 different crank lengths. So not just swapping the pedals but also going into the computer to change crank length, calibrating, then re-calibrating after riding a bit in case the pedals had tightened up. Quite tedious as I was often doing this almost every ride.

If you’re going to go power pedals I’d go Assioma as the most cost effective and proven option. But if you do ride different bikes on most rides I’d seriously look at other power meter options that mean you can just get on and go.


I don’t want the Shimano ones to begin with, so that’s not an issue. I agree, half a millimeter is a non issue :wink: is there some extra but or bob that’s part of the power pedal interface that that measurement doesn’t account for? Like the measurement is taken from the distance between X and Y, but because of Z, and which is another five mm, it’s actually more (hopefully you get I’m just using general ideas, not literal axis or distance measurements)

Thanks for all the input everyone…I would have replied sooner but… sleeping.
I think I will look at the shipping time on the Assiomas before making a decision
Oh, and @cartsman I agree, however I have a dedicated training bike for day to day with a single sided stages, so luckily it would only be fire racing that I’d swap.

Only problem will be if you get 2-sided pedals and discover you have not just a L:R imbalance but a L:R imbalance that varies on different rides and at different intensities. At which point you won’t trust left only power any more! (Speaking from personal experience in case you hadn’t guessed, though in my case that information has helped me work on that imbalance via bike fit and strength work so that it’s much smaller and much more consistent than it was a few years ago when I first discovered it).

My cleats are all the way out, so shoe all the way in, and I do not contact the power pod.

The measurement is from the crank interface to centre of the pedal. All in the video linked above. I don’t know what you mean by “not literal axis or distance measurements”… If you’re talking q-factor and pedal width that’s the only information that matters.

All I was trying to ask was if there is some extra part, measurement, or variable with those power pedals that is not accounted for in their Q Factor measurement that impacts the actual fit. Imagine if you bought a fizzy drink that said it was 16 ounces, but the special cap weighed 6 ounces. While the entire thing is 16, the cap is almost a third of that.
I wanted to make sure it wasn’t the same scenario with the pedals, only for fit, before committing to them :stuck_out_tongue: but it sounds like they are pretty close to perfect!

Not to speak for @dcrainmaker and @GPLama but based on their videos they have had the Powerlinks for 6+ months before the embargo seemingly lifted and they had high praises for the Powerlink’s reliability and accuracy.

Granted they are notable reviewers and Wahoo would ensure they had “review ready” units but I imagine if there were reliability issues it would have came up in their testing.

Granted two units across two reviewers is not a big sample size but it does seem Wahoo got it right and I am looking forward to my pair getting delivered this week!


I’ve had dual sided before, went back to single sided and am sticking with it. My single sided power meters include Stages Ultegra, SRAM Rival (Quarq), and Garmin Rally XC100.

L/R balance is an overrated metric that doesn’t really provide you with any actionable information.


Good to hear!
