Pedal power meter-Need expert recommendations before buying

Equipment

Hey folks
Our old power pedals finally quit mid ride perfect timing, right. Now we are torn between the Favero Assioma Duo and the Garmin Rally power meters.My wife is leaning toward the Assioma Duo smaller profile rechargeable battery and it looks cleaner on the bike. I am eyeing the Garmin Rally since it integrates perfectly with my Garmin head unit and has that rock-solid accuracy everyone swears by

@ponam45 Had issues with the Garmin pedals but none thus far with the Assiomas. I have the Pro MX-2s.

Also this thread might help:

I thought the new Assiomas were the undisputed champions of the power meter pedal world? I think you get everything from them that you can get from the Garmins (e.g. Cycling Dynamics) and they’re barely even half the price.

*I should add that although I had some Garmin pedals in the past, I currently have spider-based Quarq PM’s, so the above is based entirely on other people’s opinions.

Another one for Assioma been using them for years - had a pair of Vectors but Assioma far better value.

I have recently bought some Assimos and use them with my Garmin head unit. Work seamlessly, set up was a doddle. I bought the SPD versions then some spare SPD-SL bodies so I can swap between road and mtb. Changing the bodies is easy. Definitely recommend.

I also love my Assioma Duo shi. I have had no issues, and you can use a variety of pedal bodies–including the SPD/flats that I’m currently running.

I have developed some play in one pedal, but not sure if that is assembler error or not. Assioma also sells replacement parts, including the full spindle (sans sensor unit).

Did you buy the spare SPD-SL bodies directly from Assioma too, or was there another compatible pedal body you had?

Standard Shimano PD-M540s work fine. If you google, you can find what people have fit successfully, even against official recommendations.

I bought them from Assimo. Didn’t occur to me that others may fit. Could have saved a few quid! I bought the mtb pedals set plus some spare SPD-SL bodies (for some reason it’s slightly cheaper to buy them that way round).

Mine had a bit of play when I assembled then, turns out I just hadn’t torqued them up enough. If you aren’t already, would recommend using a torque wrench.

Another vote for the Assiomas. They were recommended by another rider at a training camp three years ago. I bought the spindle kit to swap out on my Ultegra pedals. They have worked flawlessly. I have been using SPD SL pedals for 10+ years and it was nice to not need to change to a different cleat.

I’ve been fairly pleased with my assioma duo BUT have had issue with their accuracy.

When I stick them on my Kickr bike, the LEFT pedal reads consistently around 5% lower than the bike but the right pedal is almost identical. My R/L balance is around usually 49/51.

I used the DC Rainmaker tool to look at the data from the fit file, and posted the results on his website and he was kind enough to reply (from #706 onwards) Wahoo KICKR Bike In-Depth Review | DC Rainmaker

Did seem that I’m not the only one; but I’m out of warranty now.

I have the Assioma Duo Shi. These are “bolt only” - you connect your own pedals to it. They support Ultegra but not Dura Ace pedals. The new models include the actual pedal. I’ve found the Duo Shi to be rock solid over the years, and support from Assioma has been fantastic. They found a fault in the batch that mine were made in, and it was literally 2 mins in the app to complete a couple of shipping details and they couriered a replacement set to Australia. They pick up dual power with any head unit that supports it no problems. The trainers don’t however, so if you’re doing indoor you’ll only get aggregate power mode - that’s a limitation of the Wahoo app, not the devices. But honestly indoors it’s not a big deal; it’s easier to focus on your form indoors than when you’re dodging traffic, pot holes etc.

The 5% difference may be a problem with the bike fit on your KICKR Bike. A professional bike fit on my outdoor road bike by an experienced Physical Therapist almost completely eliminated a 10 percent difference in my Left/Right power split, a split which showed up on both my carefully calibrated Assiomas and the spider-based power meter on my gravel bike. Duplicating that fit on my KICKR Bike improved my post-ride comfort and my power output.

Maybe - I’d like to get a bike fit anyway (as I’m toying with actually getting a road bike having done 30k km on the Kickr Bike :rofl:)
For LR balance the assioma report a 49/51 as does the gym wattbike - the 5% is sooo fixed (see the graphs I uploaded on the linked DCR thread) that it looks like an artefact rather than physiology!
