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

I’ve been riding spd for years on mtb and gravel and never experienced it before. Odd.

it’s a very common problem. You can verify with an internet search. I use WD-40 when I can, douse the cleat, and the pedal interface. Careful around bearings as it’ll take the grease out.

Sometimes I wonder if it’s the cleat to shoe interface that is creaking, but I never try to put grease under the clear when installing, so never know.

for those experiencing noise, which cleats are you using? Xpedo cleats or Shimano SPD cleats?
Wondering if it is a matter of material or fit.

I am using Shimano cleats. I asked the same question and others said the Xpedo ones are worse.

Shimano SH-51. But, I have this noise issue on my Shimano pedals as well.

The Xpedo cleats, I had problems unclipping on the Xpedo pedal. Almost fell over a few times. The middle part kept catching on something and couldn’t dislodge my foot. I eventually broke the middle bar on the Xpedo cleat.

I can try some Wellgo cleats, but I doubt they will make any difference.

Here’s another thought. Shoes used with SPD pedals (and MTB shoes in general) are supposed to have those rubber lugs on both sides of the cleat. They contact the pedal body and help stabilize the shoe. If your shoes don’t have this, maybe that’s what is causing your squeaking, or at least making it worse.

Here is an adapter to convert road shoes to MTB. It includes the logs that I am talking about. Just make sure that you trim them if necessary to keep them from contacting the Assioma pod.

@huges84 I don’t know about other people’s experiences, but I found that those adapters did not last: the rubber lugs / edges just wore away after a short time [a month or two].

Thanks, but all my shoes are proper 2-bolt SPD shoes. I mostly use Shimano shoes.

The fact that the pedals don’t spin freely would concern me. It’s probably introducing a fair amount of friction, which means the power meter is going to read low. The question is how much effect it has.

It would be nice if you could compare to another power meter and share the results.

Looks like your instincts were right. I was watching the power numbers yesterday during my ride. It wasn’t the most controlled or scientific test since my first priority was just to enjoy myself. Also, this was a first ride with a new brake/rotor set with a bit of pad drag going on on the front wheel.

Having said all that, the crank and pedal spindle power numbers were about the same during light pedaling at 150 watts. However, there was a noticeable difference as my power went up over 200 watts. At 300+ watts, I was observing a consistent and repeatable deficit of 25-30 watts at the crank vs the pedal spindles. I didn’t notice this kind of difference when I was running the TRVS Duo pedals.

So yes, the wellgo M194 pedals work and are much closer to proper flat pedals, but that’s a fair amount of wasted power. That puts me in a tough position. The Duo pedals really aren’t fit for purpose for technical MTB riding and these seem to be throwing away at least some power when I need it most.

Hopefully somebody will find a better flat pedal fit for technical MTB that plays nicely with Assiomas.

Shame there’s no easy to search resource of pedals / types of axles. I bet there must be something out there that would fit properly.

I’ve started using the Xpedo CXRs in anticipation of doing this hack, and their cleats as well. Through the pedal stroke I feel a decent amount of play up and down (x axis), especially at the top of the stroke when I’m pulling up. I’ve checked and everything is tight, is this normal?

I have the CXR’s and I haven’t noticed vertical play, but I wasn’t looking for it.

Are you using road or MTB shoes? Do you have anything between the shoe sole and cleats?

MTB shoes, VR90s. This is the first time I’ve used a MTB system though so not sure what to expect.
