A Wild idea for Favero Assioma pedals [MTB SPD Hack]

I didn’t use any washers.

Great, sounds like a very simple easy conversion, thank you.

I’ve read a lot of confusing statements on this so I thought I’d ask the question again, but will Assioma DUO-Shi fit with Shimano PD-ES600 SPD pedals without any hack or additional pieces ? I’m aware that there might be a bigger offset (4mm?) than the stock thread, but there doesn’t seem to be a definitive agreement about this online.

Same on one of mine, but only after several 1.000 km, plus it’s 5 years old now.

Unfortunate because this is exactly the concern many people had for the non-replaceable battery that Favero ensured us wouldn’t be an issue. Expensive as hell for such a fatal flaw.

Here’s an example of the PD-ES600 pedals

Hi, I’ve screwed the Shi spindle into the Shimano PD A600 body and have met with resistance a bit earlier than expected, should I stop or carry on tightening, your advice would be much appreciated? If this is how it should be then, maybe I should add the 3 washers as you did with the ES500’s?

I think I had a gap. Have XT pedal bodies on the spindles now. This shows and addresses the space issue. o-rings okay but not essential.

If that’s the increased width, you’ve got it threaded in as far as it will go. Some pedal bodies come up snug, others will have a gap.

Well….I’m taking my chances and ordered the Duo Shi spindles and PD-520 pedals.

I’ve been running the exact same setup on my gravel bike for 2+ years. Thanks to @SpeedyChix. It should work out very well for you.


Did the original conversion suggested in this thread to the xpedo pedals. After a pretty gnarly gravel race in torrid conditions the disengagement (clipping out) is becoming pretty sticky. Any tips to remediate the springs? Just some WD-40 and then lube?

Here’s an image of the 520s successfully in use.


Hi all. Apologies if this has been covered, but is this hack possible using the UNO/single-sided Faveros? Not sure about different axle lengths, etc…

I have squeaks on my SH-51 cleats and Xpedo-pedals. Using the S-Phyre XC-shoes.

I did the single side with the bontrager pedals, no issues. And I just use the original bontrager right pedal with the modded assioma left pedal. Didn’t see any need or point to modding the non-power assioma. However both of those pedals use the same size hex wrench for install, so makes it easy since I switch them between road and gravel bikes frequently.


Awesome, thanks!

If anyone is looking to play around with this pedal setup I have a set of the xpedo baldwin pedal bodies that I was going to convert but never did. They are dual sided and one pedal on one side the pedal clip is broken, but paid $25 for them. They still work fine and the other side of the broken pedal works like new. If anyone wants them let me know!

I was wondering if anyone can help me here. I am setting up my Assimo Duo Shi’a and can’t seem to be able to accept the terms and conditions to move on to setup completion. I have to be missing something. It’s just kind of gray and when I click on or near it, nothing happens.

Looks like there’s a sneaky hidden checkbox just behind the activate button you need to tick. (Maybe a UI issue with the app/mobile device you’re on).
