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

…Just to bring a few relevant quotes together.

Anyone has info on whether the thrust Nxl would work on favero? They seem exactly the same form and size as the favero’s and for 79usd you would be getting both bodies and a set of bearings.

Hi, which shoes do you got there on the 4th picture? It seems to fit without cutting your shoe right?
I just bought the SHIMANO SH-XC501 and wonder if they fit the hack without cutting them?!

He’s got last years Shimano XC7. No cutting was needed. Looking at the SHIMANO SH-XC501 it looks like the same shoe. This is his https://www.probikeshop.com/en/gb/shimano-xc7-mtb-shoes-black-2017/131266.html

Xpedo’s site, TITANIUM SPINDLE KIT – XPEDO, lists the titanium spindle (axle) kit as fitting the “… M-Force 8, Baldwin and CXR …” pedals as confirmation of fit.

I’ve successfully installed the Favero Assioma power meter pedal axles on Xpedo Baldwin pedal bodies. Haven’t tested them yet. And I did have an issue with binding but determined that it was due to the outer bushing/bearing on the Xpedo Baldwin pedals. I compared the function of the outer bushing/bearing & found out that the Favero’s were fine but the Baldwin’s were notchety. Will eventually order a bushing/bearing kit but for now I’ve applied red Loctite & then tightened until binding occurred & then backed off until smooth again. There’s no lateral play in the pedal axle with this adjustment.

I also tried swapping out the inner pedal axle combi washer/o-ring & the Favero axle still bound in the Xpedo Baldwin pedal. FWIW, the original Baldwin axles with their original combi washers/o-rings have no binding in the Favero pedal bodies.

Yes, it looks Like they have the same base!
Thank You very much :+1:

Do you have a picture of the Baldwin on the Assiomas? Curious if it could be used as flat pedals without SPDs, or if the pod would be too intrusive.

M-Force 8’s spacer/o-ring I got was 4.05mm thick.
Tried on Assiomas, and it binded.

Realized it was pressed onto the Xpedo axle by about 1mm; I compared to the other pedal that I hadn’t tapped the spacer out of yet. If I just put it back the spacer on the Xpedo axle, the bearings would bind, so the ~1mm press fit was necessary.

The Assioma axle’s shelf is a bigger diameter than the Xpedo axle’s shelf, so it probably can’t be pressed further.

I got some 500 grit sandpaper, and sanded in alternating circular motions and rotating the spacer every few seconds to keep it flat and even. 3.75mm thick would still bind when tightening to 4Nm for my pedals. Went further down to 3.65mm, and now it’s smooth, and can’t feel any play! Took about 5-10minutes of sanding per washer. Other side wasn’t as smooth, so I went down to 3.61mm, but I think that was just the bearings themselves as it stayed the same.

Here are three pics of the Favero Assioma axles mounted in the Xpedo Baldwin pedal bodies:



Don’t think I’d use them as flat pedals by themselves but I’d try them with SPD platform adapters. Those might be enuf to clear the Favero Assioma power pods.

Thanks for the pictures. I agree flat shoes on those wouldn’t be good.

Before I got my Xpedo bodies, I used Flypedal V2 platform adaptors on the road bodies. Clear the pod fine, but I filed them a bit just in case there was any flex.

I wish I could use the flat adaptors on the SPD bodies, but since there is no rubber tread, all the force goes through the cleat. The metal on metal seems like bad idea and wasn’t designed for load to go through that way, as iamholland mentioned a few post earlier as well.

The metal on metal contact wouldn’t be an issue for me. The plastic alternative is too subject to damage &, potentially, flex - so my preference would be a metal SPD platform adapter. And that’s exactly what I have. Only it’s no longer made but is similar in design to the one I linked to.

What 9mm socket are you guys using to remove the nut on the spindle when converting? The walls on the one I have are too thick to fit, and I’d rather not have to buy a bunch of 9mm sockets just to find a thinner one.

Tekton ¼" drive 9mm are just under 13mm so they should work. Plus they sell them individually and offer free shipping if you sign up for an account instead of checking out as a guest.

i just asked a local bike shop to do it. they made all kinds of noises about out-or-warranty and such, but they did it.

Not sure where you are, but I bought a small kit for AU$13.99 (after GPLama’s advice on what he used). Scroll up for the link. It worked perfectly and my conversion went off without issue. Also got a handy ratchet handle which I use more often than I expected.

I’m in the US. I went ahead and ordered the Tekton one that @TheOtherOne suggested. I was able to get it for $5 on Amazon with Prime shipping, so not bad at all. Hopefully it should work out. Thanks for the suggestion though!

Anyone have issues with Cycling Dynamics?

I record with a Garmin Forerunner 945. There are a bunch of glitches for peak power phase values.

If I ride on smooth pavement, etc, I can get it to not report the glitches.

But normal riding, and especially gravel, the glitches are all over the place.
The averages get thrown way off with these glitches.

If I dual record with the Garmin Edge 520, the glitches aren’t there. But, Edge 520 isn’t officially supported and won’t receive the metrics without the forerunner also running…

I checked data from before I got SPD pedal bodies, and the same issue was there.

Anyone else also record Cycling Dynamics?

Hi all,

I’m planning to transform the assioma to spd.

I now have an assioma duo, and my idea would be transform it into two assioma uno, is it possible? If possible, i’d use one for the mtb bike and the other for the tarmac.

Thanks,

Unfortunatly but unsurprisingly, you can only make the left pedal into an UNO.

Mike

OK so this hack having been out a little while now, has anyone been brave/foolish enough to take them on some proper mountain bike rides? :smiley:

I’m talking mainly XC stuff but riding proper trails with the odd jump, rocky/rooty section etc?

I have a set of Unos I’d be keen to do this with but my gravel usage would be secondary to being able to use them for XC stuff. But would rather not end up with a snapped pedal spindle sticking into my leg.
