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

Hello,
Do you have a video or link of that shows how to put on the Shimano M520 to the Favero Duo-Shi?

Just follow the four pictures manual. It’s that easy.

You need to have at least 75% battery for the update to show

Fair enough, with mine it never appeared - I looked at the manual and it said needed 75% battery - I changed the pedals, then when went into the app the firmware update was avaliable.

Thanks.

Grab one of these wrenches (gray plastic), loosen, remove spindle. Put pedal body on Duo Shi and tighten with a narrow wrench on the flats. It’s even easier than the original Assioma pedals to do the swap.

I converted my uno with the Bontrager comp spd but when testing out the Bontrager SPD hack vs my Suito, it’s way off (over 15-20 watts and kind of wonky). Cadence is reading fine.

When I swap out to the Look pedals that the uno came with, back to normal.

Not sure if you’ve tested them out? I swapped spindles on the Assioma and used the screw and end cap on the Bontrager pedals. Couldn’t use the Assioma bearing cap since it pushed against the rubber gasket on the Bontrager and can’t get the small nut on.

Bump. Anyone? Can’t be the only person looking for a non crank based PM option.

Thanks for the heads up. I haven’t noticed anything wonky going on so far, and the reported power seems to be similar to what I was putting out on my previous single sided crank arm power meter before it became a random number generator, but I don’t have anything else to compare it to right now. I’ll have to try it out with the road pedal bodies to see if the readings are similar.

I also used the bontrager end caps on the assioma spindles, and tightened everything according to the specs in the bontrager manual with a torque wrench, and everything seems to be spinning freely so far.

I also torqued everything to spec using a torque wrench. I connected it to my Edge 530 and rode in Zwift with my Suito to check the differences and it was way off. Then I connected it to Zwift to make sure it wasn’t my Edge 530 and still wonky.

Replaced with Look pedals that came with the Assioma and no problems afterwards (expected differences of a few W). I put the Bontragers back on again, and same issue. They pedals spin as freely as they do on the Bontrager spindles… so it’s a bit baffling.

How about recalibrating after switching pedals?

I recalibrated using the Assioma app and with the edge 530 each time I reinstalled the pedals and tested. Fit looks perfect, they spin like they do on the Bontrager spindles, but power is off.

I am planning on doing the hack with Xpedo CXRs soon and will be using them on my road and gravel bike.

What do It have to look out for when buying SPD shoes? Can they basically all be cut to fit if necessary?

I didnt have to modify my Recon 3.0 from Specialized… They work just fine with the CXRs.

Good to hear. May I ask your shoe size?

I wear size 43!

try some cheap stuff for transfer to flat pedal :joy:



Anyone able to comment on how Bontrager and the various Xpedo’s (CXR, M-Force 8, etc.) compare to each other? Which feel the most like Shimano XTRs relative to float, engagement, clicking out…? I currently have Look X-Tracks that I like a lot but I’m keen to add power recording to my MTB. Thanks.

I preferred the iSSi Flash III to any of the Xpedo bodies for engagement. Still have one set of low use iSSi pedals left from that experiment. Converted a few for local riders. I ended up going with a SPD mtb pedal body on the Shi Duos as I still prefer that engagement overall.

Thanks for the info.
