I would advise caution when considering putting duo shi in anything that they are not listed as compatible with. I bought a set about 2 weeks ago, put them into my 520’s and they never worked, got a couple questionable readings, then nothing, would not calibrate. I contacted their customer service and needed to provide them with a ton of pictures and of course a shot of the pedal bodies. Here is their response to seeing this.
“ I checked them and noticed the Assioma DUO-Shi axles are installed on SPD pedal bodies. Please consider that Assioma DUO-Shi has been designed to be used on road bikes and, as you can see on our website, is compatible with specific Shimano® SPD-SL® pedal bodies, including: PD-R8000, PD-R7000, PD-6800, PD-R550 and PD-R540.
For this reason, by installing the axles on incompatible pedal bodies, you may unconsciously have strained the pod of the sensor and damaged the product.
At this point, I need to forward all the necessary details to my colleagues, who will carefully check the situation you are facing and provide you with the best solution for you.”
I never even tried them outdoors. I am still awaiting their response. I am completely dissatisfied with their customer service. I get one email every 2-3 days after I respond. It’s infuriating. I’m not sure what they are going to say but I’m quite nervous about the $600 I spent.
So, not to be inflammatory, but you bought something, used it (albeit didn’t get to the point of “proper functional use”) NOT as it was intended but then expect support from the manufacturer?
Unfortunately they’ve got a clear “get out of jail free” card with you having admitted to trying to fit them into pedal bodies they aren’t advertised to work with. Even if they were faulty before you put them in those SPD pedal bodies or it was something totally unrelated to you using SPD pedal bodies.
Favero were pretty good when an axle unit failed on my assioma pedals inside a year, but the second time an axle failed outside of the warranty period and I had to pay for the replacement part. Which was fair in my mind, despite being pretty costly, and to be fair they were quick to deliver.
That’s why I’m advising others to think twice before doing it. I think I should be able to expect a bit more responsiveness. It’s all well and good if it works but if it doesn’t then what? That’s all I’m saying.
Weird. I’ve been using Duo Shi’s on M520’s for over a year on the rockiest trails on the east coast and though the pods look pretty beat up, they still work flawlessly.
put the Duo-shi into the recommended shimano road pedals and see if they work. is still no, then re-approach Favero (with diff email -haha). if you did everything right then the units sounds defective.
i have 3-1/2 pairs and i been swapping the axles in and out of various mtb spd/shimano pedals AND non-shi axles in and out of “shi” housings. these pods are great and with the inexpensive xpedo/wellgo/shimano-shi options you can almost find any type of pedals you want AND CHANGE BTW THEM.
For “dad pedals” - I recommend the XT version of the pedals if you’re still in the market - the T8000. The reason being is:
*They are a bit wider (but not too wide) inside and out, which is important for foot safety with soft sole shoes on a trail, and more supportive, soft sole shoes again.
*They are concave shaped - for me, this was a way more comfortable and confidence inspiring than flat flat pedals. If you’re a forefoot pedaler with flats, you’ll love the concave shape. Midfoot pedalers, i hear, tend to like flat or convex shaped pedals.
*The shape again - you can pedal the “flat” side while wearing a performance (smooth sole) gravel /xc shoe. With my sworks recons, it’s a nonissue if you find the wrong side.
BTW - I tried nice flat pedal adapters, which were awful.
I’ve been using these for a month after trying a few other pedals I have laying around for the wife/kids. They’re great. The SPD side is the default up side, and since you can pedal on the wrong side, you can mash your foot down without concern. They feel great while wearing Vans. Overall, I don’t see a need to put my double sided pedals on, even for a big day out on a difficult trail.
Would these work with the original Assioma spindles as requested in the post you reply to? I figure that isn’t the case, but if so I would be swapping over immediately since I love my t8000 and have a set of unused Assioma duos.
Looks good.
Would you mind sharing your experience with it after this period of usage?
If you are satisfied with it I might try to do the same thing and that way get a flat pedal power meter for a reasonable price.
I was thinking on getting just the left SHI model and use the original right PD-GR500 pedal as it is.
Given that you have to cut the left pedal making it shorter (if I understand it correctly) it would somehow compensate the difference in length after the SHI installation, right?
Confirming that the Wellgo WAM-M19 seems to work. Very easy direct swap. Good option for NZ where I couldn’t find any places selling xpedos or bontragers.
I’ve done a quick spin on the trainer and the numbers look ok at first glance. About 2% difference, but I need to dig into that a bit more to confirm.
Edit: I swapped back to the Favero bodies and the difference between trainer PM and pedals is consistent across pedal bodies. So I think the Wellgo hack is producing close power readings.
Couple of caveats:
I had to remove the favero steel oil retainer ring as it doesn’t fit with the Wellgo rubber seal on the crank side of the pedal. I think the rubber seal will still provide the same level of weatherproofing as on the original Wellgo pedals. But I’m a bit worried that it might abrade the plastic favero pod over time, as the rubber seal spins against it where the oil retainer didn’t.
I notice that the Wellgo axles don’t fit into the Favero pedals. The Wellgo axle seems to be slightly larger than the Faveros. I wonder if this could lead to the bearings slopping around slightly in the converted pedals and wearing out faster. Time will tell I guess
Pedals that absolutely do NOT work with the Duo Shi spindles:
PD-GR400
PD-GR500
PD-MX80
PD-T8000
Just tried them all with my new Duo Shi spindles. Even went so far as to modify the used PD-MX80 (GR-500=lower quality version & GR-400 even lower quality version) as per one of the posters in this very long thread. Apparently absolutely no thought was given to Duo Shi spindle end support bc there is NONE! And folks wonder why Duo Shi spindles in kludged together pedal bodies are wonky or just (most likely) outright fail. Where’s the emoji for “Just shakes my head”? Seriously, more thought needs to go into adapting pedal bodies onto the Duo Shi spindles. Wasted my time & money thanks to poor recommendations in this thread. Exhibit ad infinitum is a recently posted pic of a pedal with the Duo Shi spindles obviously improperly installed bc there’s shoulder exposed that should be fully hidden/seated inside/against the pedal body. C’mon! Think before doing folks. Unless wasting time & lots more money is your reason for being.
Thankfully I did find one pedal body recommended here that I like that DOES work with the Duo Shi spindles: PD-EH500.
Does anyone know if the possibility of installing road pedalbodies onto pro mx spindles exist? I have seen lots of effort trying to find compatible spd bodies with original assioma spindles but no reports the other way round… Generally speaking, I would say it is more interesting to adapt road bodies to the mtb spindles: no pod, longer battery life… I have no idea about what should be investigated, that is why I ask. Thanks a lot in advance!
This isn’t a possibility given the needle bearing system that the Pro MX pedals use. With that said, I’m sure its not long before Favero release a SPD SL system that doesn’t have a pod, as they are obviously aware of the Q-Factor(and form factor) of the pod to be less than ideal for many. I was holding out for a few months hoping the’d come to fruition, but eventually pulled the trigger on some Garmin Rally RS200’s for less than the Favero’s.
Thank-you for that! I wanted to know before I start pillaging the bearings. Yes, I do plan on trying to get them from my local bearing shop in town. This buys me a bit of time as they are making some terrible noise.
The outer hub of the inner bearing sets can get “stuck” within the pedal and become unremovable when the bearings go bad. There are tools out there to remove them, but it’s not the sort of thing a regular person has sitting around their garage.
As a follow-up, I pillaged the bearing from my xpedo mtb pedals and all went well. They were perfectly clean inside with the original grease in tact. Now I have to find a local source for the bearings - the official kit is crazy overpriced - especially with the outrageous shipping prices on top.
