Favero ASSIOMA Review – Longterm Report

Favero Assioma Review Duo Uno Power Meter Pedal WAHOO ELEMNTMy original Favero Assioma Review was from August 2017. Almost 3 years on they are still going strong. They are mostly like an HRM, in the sense that you just forget about them when you are using them. They always work and your only concern is the numbers on your Wahoo ELEMNT/Garmin EDGE not being as high as you might like them to be 😉

There’s lots of positive points and a few negative points included below, and I really had to think hard to find some negatives. The VERY detailed review is linked to, below, if you have half an hour to spare for a good read.

You could probably save £100 by buying something else but I just can’t understand why many people would need a fixed, crank-based solution when you can have versatile and accurate power meter pedals like these. Why would you want to buy some marginally prettier Garmin Vector 3 units? Garmin has probably just about sorted out all the early teething troubles now with the Vector 3, haven’t they? Maybe. Perhaps @ $1000 hey ought to have done but…

My Favero ASSIOMAs were probably the first pair ever in the UK. #NoTeethingTroubles. Go figure. Great Design. Great Build.

Assioma Longerm Review - Summary

Favero Assioma Review Favero Assioma Duo Uno Power Meter PedalI’ve used my Favero ASSIOMA Dual pedals as my main power meter over many thousands of miles. I’ve done an Ironman, several Halfs, the Alps (well some of it), the Pyrenees (well some of it), TTs and faffed around my local park many, many times. I’ve used them for trail rides, I’ve used them in the rain. I’ve used them a lot, they’ve not once let me down.

I’ve changed them from bike-to-bike, when needed, in less than 5 minutes each time and I’ve never run out of juice. I’ve never had problems pairing them to anything or calibrating. They look nice enough.

Favero has added some sweet little firmware upgrades over the last couple of years with and accuracy update matched the best-claimed accuracy from all other pedal power meter solutions and that was followed by the introduction of the more advanced Garmin Cycling dynamics metrics (except PCO).

They’re not perfect but they are one of the most reliable bits of kit I’ve got, which is unexpected when you think of the knocks and suchlike that a pedal can get.

Are they the most expensive power meter pedals?…nope. They’re one of the cheapest and CERTAINLY (IMHO) the best value-for-money.

Other than making them a bit smaller around the hub and supporting Shimano cleats I can’t really see how any improvement would materially change how much I like them.

This is definitely one you will end up recommending to all your mates.




  • Kinda just ALWAYS works
  • At least as accurate as all other PM pedals
  • Nice looking
  • Cost-effective
  • Sturdy
  • Easy to change between bikes…literally like changing a pedal 😉
  • Dual-channel BLE and ANT+ works with anything
  • Simple to calibrate before each ride..takes 10 seconds and ALWAYS zero offsets correctly


  • ASSIOMA require Look/KEO cleats..not Shimano. Grrr. This is THE most annoying thing.
  • Can be hard to unclip on earlier versions but the current version allows for looser pedal tensioning
  • Can be hard to clip IN. This is because the pedal could be better-weighted and spin around less than it does.
  • Needs a shim when I use my Pyro platforms which is annoying as I haven’t got a shim (Edit…I have now)
  • I am not convinced that the results with elliptical chainrings are correct, despite 3rd party studies. Power readings seem higher with ellipticals on my TT bike.
  • I’d prefer the ‘hub’ to be smaller.
  • That’s it…I’m struggling.

  1. I couldn’t agree more, I’veI messed with Garmin vectors for years from the 1s and 2s and so was reluctant when I bought these, I only bought the single sided version for fear that they wouldn’t be that reliable…. I’m looking to upgrade because they have been excellent.

  2. Hi the5krunner, completely agree with Assioma being reliable and have been working well on my bikes for over a year. I went from Powertap P1 to Assioma and never looked back.

    Just wondering what power difference you’ve found with oval chainrings. I compared round and non-round chainrings on the same bike using Assioma and Neo (as control) last winter. Assioma were reading around 5% higher on non-round chainrings compared to round ones.

      1. The test seems to have been done when the pedals were not compatible with oval chain rings.
        On 2017 there was no update for IAV power.

        1. IAV released here: https://the5krunner.com/2018/04/24/assioma-new-v2-firmware-for-super-accuracy/
          I had beta before that
          you might be referring to this https://the5krunner.com/2017/08/31/power-with-ovalelliptical-chain-rings-an-anecdotal-40-minutes-with-3-pms/ which WAS produced before IAV
          I have done other tests that I have not published, hence my assertion. you have to weigh up my assertion based on unpublished experiences versus Favero’s published scientific paper.
          I would be intrigued to learn of others’ experiences with ovals and IAV (mine are ROTOR and set to quite an extreme position)

          1. Sure, I even did put devices in the bottle cage, just to double check if it makes any difference.

            I tried Laptops (Windows and MacOS with different Applications), with passive and active USB cables and even the Tacx Antenna. I tried two different Android devices with built-in ANT+. Our other power meters (P2M, Vector2) do NOT fail that much. Vector2 have the strongest signal (and never fail), PM2 is in the midrange (and fails sometimes too) Tacx NEO 1 (T2800) is strong, but fails sometimes too (but that has another reason; I think). ANT+ dropouts can be (read: are) a bit tricky as the summary of many little things… well you know it. The New Grrmin sensor hub makes no difference.

            There are some ANT+ tools for Android. They can show the signal strength… Assiomas (at least the pair I have) show always the lowest signal – especially compared to my other devices.

            During workouts I‘ve seen that the signal constantly build up and then they suddenly they drop to one or near zero. That‘s an ongoing thing, but happens only with the Assiomas.

            (My) Assiomas have very low transmission power. Maybe FW update could fix (boost) that, but for that Favero would need to acknowledge – support was chatty and responsive, but not into a solution.

          2. and you have a replacement pair to show it’s not just a one-off?
            if so, i can’t see how it’s ok on other bikes…I assume your bike is the same size!!

          3. Favero (and my dealer) gave me no opportunity for a replacement unit to check against it. And no, I‘m not going to buy a second pair just to see if it‘s only a one-off.

          4. if the ‘fault’ developed within a year then surely you can return it to be fixed?
            it has to be up to the job.
            at least that’s how it is in the uk
            2 years in the EU?

          5. Dropouts due to „weak signal“ (can be hardware or firmware) is something difficult/subtile… I know this game (company and/or dealer is playing 🙈🙉) well enough.

  3. I broke down and bought the Duo. Setup was relatively easy, just waiting for a good day to take out the bike.
