Especially for light weight issues concerning cyclocross / touring bikes & parts.

So after reading through this: https://forum.trainerroad.com/t/a-wild- ... s/18627/24 and looking for a power meter option for my Trek Checkpoint, I decided to try this hack. Favero Assioma DUO with Xpedo CXR pedals. Xpedo is apparently(?) the maker of the pedal body for Favero, and the bearing/spindle design is the same. So here are some pictures of what I have so far. It's basically just an UNO setup as I only did the left side for now.

Weights
CXR Pedals: 145g each, 290g for the pair. 65g for the cleats and hardware.
CXR Spindle: 51g
CXR pedal body and screws: 94g
Favero Assioma pedal body: 68g
Favero Assioma Spindle: 83g
Assioma/CXR left pedal: 177g
Assioma/CXR left + Xpedo CXR right: 323g

So it's a 33g weight penalty for the left sided power meter, or 66g if you want to go dual sided. Not too bad, still lighter than the Shimano SPD I have on now at 376g.

Hopefully get some power data this weekend to compare.

How's the pod go with your shoes?

I use the CXR pro pedals on my gravel rig (non-power) ofcourse... I have a stages left arm for that.

My old XTR 9000 pedals have slightly better engagement but the are passable... way better the eggbeater to me.

I like this hack... and wonder if it's possible on the CXR pros which weigh less.

That's a cool hack for sure but only for gravel riding in my opinion... Imagine that pod hitting a rock or a root which is something so common on mtb riding....they didn't invent the crank boots for nothing :lol:

So I think (not positive) the CXR Pro get the weight savings from the spindle. As far as I could tell, the body is the same or similar. So I don't know how much weight savings you'd get having to use the Assioma spindle.

I had to cut my shoe slightly. Just a little notch where the pod is to prevent rubbing. I'll post a picture, but if you look at the link I sent, I cut less than the other guy did.

They have proprietary cleats, but also work with Shimano SPD, which I'm using without any problems.

Yea, I wouldn't do it for MTB, I'm even scared to use it for cyclocross honestly. But I think for gravel rides it'll be ok.

Nice? Could you please show a photo looking side-on? Looks like the dust cap (on the axle) is kinda recessed inside... is that how it looks on the non-Assioma side as well?

Any shoes with lugs will need to be filed/modified to clear the pods. My overshoes rub the pods with road shoes...

I'm wondering if you swap the cheap nylon injected pedal bodies that come with the Assioma's with the Xpedo Carbon SL's if it saves any grams.

Currently the Assiomas are ~30 grams more than the Keos they replaced.

Less than 30 minutes. The outer cap is an allen key, I think a 7mm(?) and then you'll need a 9mm socket for the inner nut. I'd recommend a torque wrench for reassembly. But it's an easy job.
