ASSIOMA Review – Longterm Report

ASSIOMA Review – Longterm Report

Favero Assioma Review Duo Uno Power Meter Pedal WAHOO ELEMNTMy original Favero Assioma Review was from August 2017. Almost 2 years on they are still going strong. They are mostly like a HRM that you just put on and forget about. They are just another sensor that always works and your only concern is the numbers on your Wahoo ELEMNT/Garmin EDGE – you know the numbers are correct but that you wished were a bit higher 😉

There’s lots of positive points and a few negative points included below, and I really had to think hard to think of some negatives. The VERY detailed review is linked to, below, if you have half an hour to spare. 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. Go on, you know you want to buy some marginally prettier Garmin Vector 3 units. Garmin have probably just about sorted out all the early teething troubles now with the Vector 3. Maybe. Perhaps @ $1000.

My ASSIOMAs were probably the first pair ever in the UK. #NoTeethingTroubles. Go figure.

Favero discourage discounting. In Europe the link above will take you through to the Wiggle & PowerMeter24 options – depending on exchange rates thelatter usually have the best price (specifically check club deals)

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.




  • 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


  • They only take the 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
  • Needs a shim when I use my Pyro platforms which is annoying as I haven’t got a shim (PS…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.

        • did you try putting the receiver close to the PM? to see if it is a factor of weak signal due to distance
          are the results the same with the newer Garmin sensor hub.

          • 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.

          • 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!!

          • 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.

          • 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?

          • 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.
