I'm searching for a powermeter but also I don't want to break the bank.
The product that took my interest are:

• Magene pes p505 299.99 euros
• Favero Pedals Powermeter Assioma Uno 409.99 euros
• INPEAK POWERCRANK-E for Ultegra r8100 (my currently crank) at 389 euros

THe magene seems the more accurate, I can keep the currently bottom bracket and chainring, also seems pretty valid for the future in case I want to put on another bike. But I'm not sure about it, the inpeak seems not so accurate with the 2% tolerance and also the installation time seems quite long (I had to ship and wait).
Also I'm not sure regarding the pedals, I came from keywin and wahoo pedals but those types I never tried even once.
For me the pedals are less worth since they request even more maintenance...

Has anyone tried the magene?
Do you think will be a wrong choice?

I've used the Magene rear light/radar for a year and it has been excellent.

YEa that's why I'm interested, the brand looks very good and improved a lot since it came out.
Probably they are going to became another big Chinese brand soon

I have a P505 Base on order and have done extensive research. I am willing to take a chance. The direct swap w/ Shimano definitely help and the fact that I can use my own chainrings.

The pedals can be moved from bike to bike - for me that is a big advantage over crank based products.

Yeah, that’s why I have Assioma Duo. I’ve been using them for years, and reliability has been excellent; I maybe replaced bearings once, but it only takes about 15 minutes so I don’t even remember. Cleats wear out, too, but I move the Assioma across a few bikes, so that versatility (and consistency in the numbers) is supremely valuable to me.

I have the Magene, so does my wife. Love it. Prior to this I used 4iii and Stages. Absolutely excellent product.

As long as the BB is compatible, moving a crank-spider-based PM is simpler and faster than moving two pedals (if you have the right wrench): there's only one fastener to undo and tighten, rather than two. But in either case, we're talking a difference of maybe 90 seconds for replacing a crank spider PM and maybe 3 minutes for replacing two pedals, so the difference is pretty unimportant.

Here's a video of my friend swapping a spider-based PM (in this case, a Quarq, but others are similar):

I have the Favero Assioma Duos (w/Shimano pedal bodies) and I'm totally happy with them. They seem fairly accurate and just work without any issues. Unlike my Garmin pedals for my MTB and gravel bike, that require use of a torque wrench to even get somewhat accurate readings.

How much maintenance did you read that PM pedals need? I've never done anything other than change the batteries on my PowerTaps and have used them on multiple bikes since 2018.

chaadster

I don't know about that...but if so, that's assuming one keeps their other bike(s) sitting around without cranksets *and* that the crankset you want to swap is set to your front derailleur *and* is compatible with that derailleur *and* that the crankset you want to swap is the crankset you want on the other bike. That's a lot of stuff that needs to line up in order for a crank swap to be easier than pedals! I just use different pedals for different occasions, and have bikes that use different length cranks, 1x and 2x chainsets, standard, mid, and compact chainsets... There's no way crank swapping would work for me, and certainly not faster or easier than pedal swapping.

CrowSeph

Somewhere someone said that pedal must be disassembled every 6 months.
But now thinking I do almost the same maintenance on my speedplay.

CrowSeph

Interesting that I can use Shimano body, what are the advantages?

PeteHski

It’s just a cleat compatibility thing. The Favero pedals are only compatible with Look cleats.

RChung

Ah. I had not realized that you keep your other bikes around without pedals and you only have one single set of pedals that you use for all your bikes. In that case, nevermind.

CrowSeph

Update.
I've done some comparison with the weights.
My currently pedals are the wahoo that's weight 334g (cleats included).
The assioma (1Pm/1normal) Weight on total 345g.
That's not an huge weight penalty compared to the 50g of the crank set spider of the magene. Also seems hard to find any lightweight alternative to the currently Ultegra r8100 chainrings.

Plus swapping the assioma pedals body with the Ultegra version will reduce 77g for pair.
If I done my calculations right seems super good for a weight pov.

This made me overthinking more haha

PeteHski

I wouldn’t sweat those kind of weight differences. Actually you could sweat 50g just thinking about it 😂

chaadster

Ha! Well that’s not quite the case, but is closer to reality than the notion that I have bikes sitting around without cranks and only have one single crankset to share between them!

TMonk

Longtime powertap user that went to Favero Duo so I could have power on race wheels, especially in TT. The Faveros are great. The only maintenance I do is remembering to charge them. The charge lasts a while. They read a few percent lower than my powertap, and a few percent lower than my Saris Hammer H3, but really that doesn't matter as long as they are consistent. I'm a fan 5/5 stars and I will never go back to powertap.

TMonk

I do swap them between three bikes (2 road bikes 1 TT bike) which is sort of annoying. I'm considering a dedicated crank-based PM for my daily driver TCR so that it's just ready to throw a leg over and ride all the time. I swap the pedals at least once a week and I'd rather not have to do that,

Sierra_rider

For me, it was to not introduce another pedal system into my quiver. I already had a couple pairs of Shimano SPD style pedals across a couple of different road bikes, so it made sense to get the Faveros that came as a spindle only. The Faveros really only get used on 1 of my road bikes, as my other has a 4iiii crank arm power meter.

It depends on the rider, but the Faveros with the Shimano pedal bodies can either be a positive or negative. They have an increased stance width/Q-factor compared to standard Shimano pedals or the Faveros with the Look-style pedals. Standard pedals are too narrow for me, so that was a benefit in my case.
