Favero ASSIOMA PRO MX-2, new SPD power meter pedals

So they arrived via FedEx in the UK. And then a week after they arrived I got an email from FedEx to say there was duty due of £112.50. No breakdown of how they got to that number but it’s about 25% of what I paid in GBP (dual sided). Seems a pretty poor process for FedEx, would think they would have a much better chance of getting prompt payment by not delivering until duties had been paid! I didn’t get round to paying it straight away and then when I did go to pay it said the payment link had expired and I would be getting a paper invoice. That was a few weeks ago and nothing yet so who knows :man_shrugging:

Good to know…ill keep an eye out.

had my first ride with them today. Log In to TrainerRoad

Coming from road, not sure if they’re over reading or Im actually stronger in little spikes haha

It has been approximately two weeks since I made the switch to the pro MX-2. I have been on road shoes since I began cycling a couple of years ago, and being on MTB pedals was a big change for me! I was really excited as I finally got to walk properly, and it helps a lot on gravel roads! One of the riders on a group ride didn’t notice the clipless pedals and thought that I was wearing sneakers, haha.

I initially started having knee pain on my right knee after this change, and I really do not have much room to move the cleats around. I thought it was spring knee, and I was surprised as to why my knee didn’t hurt when I was riding on the trainer this winter doing sprints, sweet spot, and VO2 max intervals. During an outdoor ride yesterday, my knee started to hurt pretty badly just 5 kilometers into the ride. I then realized that my quads were being overused and my glutes were underused. As soon as I started to consciously engage my glutes, that knee pain went away!

Just wanted to share this as it has been quite a bit of a learning curve when I made the switch to MTB pedals and shoes as a roadie!

I have been using the Favero Assioma Uno before the MX, so I am familiar with their quality, and I’ve got to say that they have done a fantastic job!

My arrived within a few days of shipping. Used them 3 times and all looks really good, Power numbers as I would expect. Very happy with the pedals.

Same for me, UK import duties were £112.50, invoiced by FedEx about a week after they delivered the pedals. Payment to FedEx was fairly straight forward when I did it.

Before that, after I ordered the pedals but before the pedals were shipped by Favero, their support staff e-mailed me to check that I realised that I’d have to pay import duties on the pedals, in addition to the price in Euros. I thought that was a nice touch.

well i can confirm that these pedals are calculating sitting vs standing based on pedal pressure / power phase and has NOTHING to do with sitting vs standing. as in, fully seated in the saddle but put as much pressure on the left or right pedal as possible while coasting and it’s counting that as standing. i couldn’t believe it but it’s easy to try for yourself. just set a data field for standing time and put various pressures on the pedals while being fully seated in the saddle and watch the “standing” time tick away happily. i’ll try to make a video next ride to fully expose it. shockingly, what it does NOT seem to be counting is actual standing time lol. coasting down a hill fully standing with the weight distributed evenly on the pedals and the time didn’t move at all. lean your weight on one pedal vs the other and the standing time ticks off.

one interesting thing is that it looks like the software (or maybe garmin?) is doing some sort of on the fly error correction while calculating standing time. i watch the standing time tick up (23, 24, 25, 26 seconds etc) and after a few seconds it resets back to (06, 07, 08, 09 seconds etc). doesn’t do it all the time, but it is doing it intermittently.

so, there’s one of three possibilities here:

  1. these pedals are defective as it pertains to seating vs standing
  2. MY pedals are defective as it pertains to seating vs standing
  3. favero has some serious issues here with seating vs standing time calculations

it’s most likely #3, but when i had the active standing time data field there were times when i was applying the pedal pressure trick to fool the standing time but then i stopped doing it and it was STILL counting standing time, sometimes for up to 30-40 seconds after.

anyway, as i said i’ll try to make a video showing this but the bottom line is we should completely ignore the sitting/standing metric as 100% made up on the mx-2 pedals. maybe favero needs to contact garmin, specifically their rally team, to figure out how they got this so wrong.

if anyone else is having trouble with this metric please post it here so we can see if it’s a widespread issue or if it’s limited to individual pedals

To state the obvious, pedals can’t directly measure whether your posterior is touching the saddle or not. They don’t have a strain gauge in your saddle or anything like that. Any such metric would be completely necessarily making an assumption based on pressure measured at the pedals and when it occurs during the pedal stroke. As such, if you are actively trying to fool it, I am sure it’s not that difficult.

Have to admit that having owned pedal PMs for several years I don’t think I’ve ever looked at the sitting vs standing metrics and not sure what I’d do with them if I did! I check the L:R balance after most rides as it’s a good indicator of whether I’m on top of my off bike core/strength/stability stuff and whether I’m due a trip to the osteopath, the rest of it doesn’t seem to serve much purpose. Just took a look and FWIW my standing/seated stats with the Faveros seem spot on with the vast majority of my time being seated.

i’m not actively trying to fool anything. it’s doing it on its own while i’m riding and wildly miscalculating seated vs standing. what i was actively trying to do is figure out how the data is SO wrong, and it is COMPLETELY WRONG vs the rally pedals, and basic logic for that matter. as i stated, it wasn’t counting standing time when i was , you know, standing…

come on man. let’s not get silly here

ok, that’s cool. the assioma pro mx pedals are still doing it wrong, whether you find value in the metric or not

It’s not “wrong” because to my knowledge nobody has defined what is “right.”
Garmin is working with an algorithm based on some assumptions, and Favero implemented a version of their own. It is safe to assume they worked independently on this. Maybe in the end the Garmin algorithm does a better job of agreeing with the actual standing vs seated time, for you or even in general, but in the end both are an estimate based on some assumptions.

also…what is the point of this metric? How would it improve your riding?

surely you just want power left vs right (if dual) overall power number and cycling dynamics? Standing vs sitting is useless no?

oh no, it’s wrong. and dramatically so. right = standing on the pedals. wrong = counting as standing when actually sitting. it’s…not that hard…

yeah i mean if there’s no point in it for you then you can safely ignore these discussions. there IS a problem in the data here though, regardless of whether you find value in it or not

If you don’t like your wrong pedals, I will offer as much as $400 for them.

idk what to say. you guys are actively fighting me in a discussion forum when i’m pointing out an issue with the pedals. i never said i don’t like them, i never said i want to sell them or return them. i’m just trying to figure out what ultimately is the problem here. minor? yes. insignificant? perhaps. but there IS a problem with this particular metric and it’s probably on favero’s end because it was a very accurate metric on the garmin rally 200s

anyway i get it, questioning data isn’t well tolerated here. i won’t comment further. i’ll let others share their experiences with seated vs standing times if they dare

Not just wrong, DEFECTIVE!

I explained to you exactly what’s most likely happening. Maybe Favero will at some point refine their algorithm. Will it ever fully match Garmin? Probably not, because the parameters for this calculation are not publicly defined and are open to interpretation.

i mean it’s possible. if you manually get the standing time to count and then stop doing it, the standing time was still counting after the fact, sometimes up to a minute after. stuck or sluggish strain gauge maybe? idk. but anyway, you have your fun. i’m done

cool, thanks
