i got replacement bearing on amazon, they pretty cheap: 6700 and 686. just look at the number on the units and match. read up on “ABEC” ratings but pedals dont spinn that much so not really a factor unless you’re anal and just want the best.
Hello. I have favero bepro. Single side power meter, with look pedal.
I also have shimano spares pd-m520 and pd-m780 (xt series).
I knows I don’t have assioma but bepro, older model, but does anyone know if I can also do the swap? Do inner axles match? Or should I try to disassemble the bepro?
IDK about the Bepro versions, but on the Assioma pedals with pods, only specific Xpedo mtb pedals bodies will fit. I tried some other Xpedo mtb pedals and they did not fit. I’m sure Shimano pedal bodies wouldn’t fit my pedals either.
Any updates on using these pedals?
More then 1000km on them, still no problems.
Here a more professional way to modify them (I also used a CNC mill to get a smooth even surface)

Got a bit of a long-term word of caution from the Assioma + M-Force 8. Not sure if anyone else has come across this, but I thought it worth mentioning.
I bought the Duos back in April 2023, then did the M-Force 8 conversion later that year because I hated how much the spinning road pedal body made it impossible to clip into until I’d kept the cranks still for a few seconds… no good when you have to take off from traffic lights! Also I prefer to be able to walk on metal SPD cleats than plastic road cleats. Shoes are the Bontrager Circuit road shoes, so no tread to have to cut out of the way.
I was unable to use the provided Xpedo cleats because the thickness of both the soles of the shoes as well as the Xpedo cleats, & the short cleat bolts, prevented the bolts screwing into the plate that I had to install into the shoe. However, the stock single-release & multi-release SPD cleats were thin enough to screw through so I used those. Engagement & disengagement wasn’t as clean as on an SPD pedal but I was okay to live with it. The connection felt very secure.
After nearly a couple of years & about 20000 km I have to report that the pedal-cleat interface has become very sloppy. The cleats have worn impressions into the pedal bodies with no such wearing down of the cleats on the sides where they contact the pedal bodies. Tension screws are at maximum tension.
It appears that the M-Force 8 pedal bodies are made of a softer material than the SPD cleats. This means a lot of rocking of the foot is possible. Indeed, it is possible for me to unclip a shoe pointing directly forward simply by tilting the knee outwards, or sometimes, pedalling in a full circle with the scrape, lift, kick action. I have multiple times had a foot blow out of a pedal simply by attempting an “English bunnyhop”.
Luckily I’ve managed to find another pair of new M-Force 8s. I transferred Shimano’s SPD/flat pedals onto the bike & I immediately felt more locked-in. (Honestly my favorite non-PM pedal for a do-everything bike.) So there was no wear to the cleat contributing to the sloppiness of the connection with the Xpedo pedals. So it looks like I’m doing the bulk of my riding without power until the new ones arrive. 
It crossed my mind to pull the bearings out & put the stock Assioma bodies (Thrust NXL?) back on but I also discovered that one of the Xpedo pedals spins like the bearings are dry. Upon inspecting, the two inboard bearings felt too dry, too smooth, & had a tiny but noticeable bit of play. One of those was rough for some of its rotation, which seems like a pitted bearing or surface on one of the bearing capsules, & was probably about to fail & strip shards off the axle of this expensive measuring device. The bearings of the other pedal were stuck inside & would not move with any amount of tapping. But they at least appeared to be functioning as a bearing should. When the new pedal bodies arrive I’ll just leave their bearings in there; that’ll double as a bearing replacement.
I was not forseeing that new pedal bodies every 18000 km would be part of the ongoing service costs. Perhaps the Xpedo cleats will wear their own pedals less than Shimano’s did, so at some point I’ll try to attach them again. But I don’t like my chances. The Xpedo website now lists power meters on a multitude of its range. Favero has made SPD compatibility available as a factory standard. This conversion was an awesome idea, ahead of its time. I’m just questioning how long it’s worth me staying on this ship for.
Has anyone tried this yet with the new Magene P715?

Came here to post the same question about Magene’s power meter pedals. I can’t find anything about replacing the pedal body or bearings that might help answer if they are amenable to an SPD swap.
The thing is that this whole enterprise with the Favero pedals was made possible because Favero subcontracted out the pedal bodies to Xpedo who in turn just happened to use the same spindle/bearing design on both their own brand road and MTB pedals - they also designed pedal bodies for a few other brands.
It was all luck really.
I have no idea what the situation is with Magene.
Grabbed a screenshot of a tear down. I think its not the same as Assioma/Xpeedo but perhaps other SPD pedal bodies would work?
Certainly looks different to the favero - have you managed to find any information on what bearings the Magene uses? That could aid tracking down compatible bodies.
Nope. Just have the screenshot.
good luck 
Did anyone ever try to fit Assioma Duo-Shi bearing cartridge on standard Look type Assioma Duo?
I went through this thread, but could not find any info related to this.
I’m looking into increasing my stance width, and was looking into this option.
Are the dimensions of the standard spindle same to the Duo-Shi spindle?
I know there is a difference in the bearing seal, that is glued on to the Duo-Shi, but I don’t care much about bearing protection for testing purpose..
If somebody has an image of both spindles side-by-side for comparison, that would help a lot.
No they are completely different unfortunately
Interesting…
Looking at the bearing replacement videos on Favero YT channel the two spindles look quite similar.
But yeah, impossible to say without a pair of verniers..
You know what, after some further research I was starting to think I was wrong - they are very similar instead.
But then found this on the Favero site….

I just got new winter shoes and they are rubbing on my spd converted unos 
i don’t really want to chop up the shoes. Is a little rub a big deal? Should I use this to just bite the bullet and get the pro MX pedals?
I’d take a razor to the rubber before spending $500 on new pedals… The rubbing could throw off power readings as you’re no longer putting all the pressure through the pedal but onto the pod instead.

Fair point I really don’t want to spend that much either. It’s barely rubbing the side so I may just try to trim a tad off. The manual says it needs 2mm of clearance but idk if thats really necessary or not.
