I’ve seen some very positive coverage of the Assioma PRO RS-2 pedals, and from a set up and accuracy stand point they look like a great way to go. For people that have been using them for a while (I believe @GPLama uses them a lot) what are your observations on durability? And is there a significant difference in cornering compared to Dura-Ace?
Re: Cornering clearance with Assioma PRO… Negligible difference compared to a standard DuraAce pedal. It was the (now discontinued) DUO-Shi with a 65-65mm pedal q-factor that reduced cornering clearance.
No issues with durability. Even when using the PRO RS on gravel a lot this summer.

Ok, that’s what I suspected from just looking at them for cornering… I figure you probably have spent the longest time with them. I guess my follow up questions is… why would I not buy them? They almost seem to be in the too-good-to-be-true category if I’m in the market for a dual sided power meter. They’re a simple swap for an item that’s already on my bike, I can easily switch them to other bikes, they’re more accurate than crank/spider based systems (I think), and they’re competitively priced. Am I missing something here? Is there a downside that you have seen?

I have a pair and like them. Off the top of my head reasons they might not work for someone:
- Wedded to another pedal platform e.g. SpeedPlay
- Need frequent pedal swaps - data stability might be better with spider-based
- Groupset/App/ecosystem integration e.g. SRAM AXS app manages both your PM and shifting
- Integration with other devices e.g. you need a Quarq for Flight Attendant to work
- Might prefer a device with a replaceable battery for longevity/field serviceability
- Single array of strain gauges in a spider might be quicker and easier to recalibrate in the long term and has fewer potential points of failure
Tom, valid points… I’m not a SpeedPlay person, so that’s not an issue. I’m also on Shimano (mechanical) so also not a problem as far as integration with a groupset…. although I recognize that my next purchase will almost inevitably be electronic shifting (sigh). I appreciate the devil’s advocate position here, but at this point I think I’ll still get a set.
25,000+ miles. A few crashes and serious pedal strikes. Completely bomb proof. Battery still as good as new.

I‘ve had a pair of the previous generation on my gravel bike for about three years. Easily used them for a 1000+ hours. I have literally zero complaints.
My duos have over 30k km on them. Absolutely zero issues.
Have also had the SPD model in use on gravel and MTB bikes. They’ve taken plenty of hits, mud, water etc. Perfectly fine 1.5yrs in (or however long ago they came out)
Believe this member. If you don’t recognize him, he’s a major equipment reviewer with outstanding insights and experience (despite his coming from that backwater in the southwest Pacific).
I am still running the set of previous Gen Assiomas that I bought in 2018. Over 20k miles and plenty of abuse later, including being relegated to my gravel rig for the last 3 years, they’re still going strong. FWIW, I ride Shimano manual GRX and Ultegra.
I think the new model has been out long enough to get a sense of its durability and ID + resolve any teething issues. I wouldn’t think twice about buying a set when (if?) my current pedals bite the dust. At this rate, they may even outlive me!

I’ve only had mine for a month, switching from Speedplay, and I’m loving them. I particularly enjoy not getting grease on my socks because I happened to have hit my pedals while stopped, and I can walk inside on my cycling shoes. Clip in is a little more cumbersome but I’m already getting better at that.
We have a few customers in our shop who use them all year round (and it’s Denmark, so conditions are… rough, especially in winter time). We haven’t seen any of them fail, at least so far.
Personally, I use a spider-based meter (P2M), but I would definitely opt for a pair of Assioma pedals in the case of a new bike (just much more convenient to work around vs the limiting factor of a spider based meter).
I went ahead and purchased a pair. If nothing else I really want to nail down any discrepancies between how the legs are performing. And this will also make it a lot easier for my next bike!

I’ve used a pair since late summer and have been mostly happy with them. They pair reliably, give power data that is consistent with the power2max crank based power meter I used on my old bike, and I discovered that there is a third party app that allows me to see the “extra” data on my Karoo 3. The only issue I’ve had that doesn’t seem to be isolated based on searching to figure out what the problem was is that some pedals were made with defective seals that show up as a squeak that sounds amazingly like birds chirping. Mine also stopped rotating as freely as they should and wouldn’t hang normally at rest. Favero responded quickly to a support request and sent out some new seals once I made a second request though the app, which was an unnecessary extra step IMO. All seems to be good with the new seals so far although the problem with the original seals didn’t come to light for ~2,000 miles or so.

I’ve been riding a pair of the new dual-sided pedals for four months, about 1200 km on a bike on a Kickr Move and about 750 km on road and gravel. Plus a scattering of track. Bottom line = no problems at all. I’ve swapped them around a few dozen times and they have always remained within a percent or so of either the Kickr or a SRAM Red XPLR powermeter crankset on my gravel bike. (On the trainer I typically watch the Assiomas on an iPad with a Garmin on the bike connected to the SRAM crankset. And I get Kickr data in Rouvy, TrainerRoad, or Zwift.) This gives me plenty of opportunity to watch for data irregularities and I see essentially none. I’ve swapped the pedals around enough to catch any problems with calibration or simply with the removal/reinstallation process (I haven’t had a reason to swap pedal bodies). I’ve had a couple substantial slides with no problems except cosmetic. They’ve been good enough that I’ve bought a second pair so I can keep the new pair solely on the trainer. (I had an ankle injury at Unbound last year and have been using the Assiomas on the trainer to monitor quantitatively my pedal stroke to ensure it returns to the same level of flexibility and power distribution I previously had.) I’ve had Garmin 210’s and briefly a pair of SRM’s and have to say that these are totally durable, more reliable than the competition, and hold their accuracy. Zero hesitation about buying them or recommending them.
My ankle is 95% back to normal and I will be selling the pair from the Kickr. They are totally mint, logged only about 120 km solely on the trainer in zone 2 cadence work, and include a spare set of charging clips. If you or anyone wants a pair at a conservative discount from the new ones, drop me a line.
I’m having an odd issue with the shipping… US Customs put a hold on them after they arrived in the country. FedEx called me and said Customs was looking for mor information, like what they were made of and what they were going to be used for. I gave them the information I had, and supposedly they will be here tomorrow. First time anything like this has ever happened to me. I find it weird they called me as the guy who is receiving it as opposed to the shipper, but it looks like it’s all good. I guess I’ll see when they arrive!
