Which shoes are people finding the best to use with this hack? Any that don’t require chopping up the sole?
Same here! Both pedal sets (Assioma and CXRs) arrived Saturday. Charged 'em up Saturday evening, assembled 'em Sunday morning, and took 'em for a test ride in my pajamas this morning (Sunday). I felt like a little kid coming down the stairs on Xmas morning all excited to rip open cardboard packaging.
Looking forward to putting a couple hundred miles on these bad boys in the next week or so. 
Edit: Had to open them up and put some threadlocker blue on the internal nut to keep it from slowly loosening. Was never able to fully tighten it down on the CXR spindle.

I use the Fizik Terra x4 powerstrap. I didn’t need to chop it.

are the CXR’s the only pedals that will work?
i prefer a flat pedal with SPD and currently use Nukeprrof Horizon’s
It does appear to require a specific type of spindle/bearing arrangement. Refer post 39 and 44 of this thread.
Hey Shane,
How have you found the cleats on the xpedo pedals? I have done the same conversion as you have but find the pedal engagement really ordinary. Every time I unclip I want to swap back to the XT pedals I was running before. I have mucked about with the tension setting but can’t find a happy place…
Power is great with the Favero axles but the pedal bodies are less than satisfying
Maybe I should lend you a pair of shimano pedals!
I agree, they’re not the best. If I use my shoes with Shimano cleats there’s too much play, so I’m happier with the Expedo cleats. I’m sure I’ll get used to it.
Edit: I’m also not planning to use them for cyclocross or hard mountain biking, just gravel and marathon MTB. So popping in and out isn’t crucial.
Another happy customer here. Used a pair of M-Force 8 pedal bodies I already had and they mounted up great. Have 8-10 fat bike rides on them already, and did some trainer rides my XC bike with a Quarq. The Favero Assioma pedals registered about 4% low compared to the Quarq across the entire range, so I adjusted for that within their app and now they read nearly spot on with the Quarq, so I feel good about getting consistent power data between bikes. BTW, this is the only real solution I was able to come up with for getting power on a fat bike. Very happy with the results.

Are you riding the fatbike on snow? If so, how does the power compare to perceived exertion compare to mtn biking or road cycling? I’ve always been curious about this.
Yes I’m riding on snow (Park City, UT) and It’s really hard to give a definitive answer to your question, but in general I don’t think the perceived effort is too much different than the actual effort (what the PM says). And I don’t think you’d expect it to be. Your legs and lungs wouldn’t know if your on a fat bike or on the snow. That said, snow conditions and tire pressure play a huge role in rolling resistance, which has a huge impact on speed and probably a psychological impact on perceived effort. Sometimes the smallest hills seem like they go on forever.
What about using Crankbrothers Eggbeater or Candy housing? Would that work ?
Can anyone in possession of both Assioma and one of the above mentioned pedals check if they fit as well.
I7m using eggbeaters for my gravel and would love to make this upgrade hack …
My gut tells me the spindle and bearing designs won’t match to allow that hybrid.
yes, that is what I was afraid of… still would love someone who has both to check…
Hey man. You’ve had a few months with this assioma spd conversion. Any issues? All working ok? Have you done any ‘harder’ mtb riding? Thanks in advance.
Hey Michael… I’m also in Melbourne… wondering where you got the wrench piece for this? I can’t seem to find what I’m looking for here…
Robert, in the end, I simply went to my local bike shop [north fitzroy cycles] and asked them to just undo the nut for me. They did have to find a special socket, but they did have one. Sockets that are thin enough to fit into the end of the pedal are indeed hard to find.
Good luck - Michael
If you have access to Tekton tools down under their 9mm, ¼ drive sockets fit perfectly without modification.

I know in the USA Amazon carries these individual sockets.

@michaelfrommelbourne - thanks, I’d like to do the transplant and be able to service these myself so will keep persisting trying to find a socket.
@TheOtherOne - cheers man… unfortunately they don’t ship to Oz. The local ones are $30-40 (we pay through the nose for everything here) and there’s no guarantee they’ll fit.
@gpl - any tips on where you got your socket from…? If you found one, they must be available here…
You know how many interval sessions it takes to burn off those snags 
OMG, $54…
I found smaller supatool kits at Autobarn, both are AU$13.99:
OR
I’m assuming the 9mm 1/4 socket is the one… and that Supatool only makes one kind of those.
