Sup guys. I´m about to buy a favero assioma power meter (was thinking of the Favero Assioma Uno), but I don't want to change to Look cleats. I noticed that Favero offers Shimano pedal axles so you can use the powermeters with Shimano pedals, but they only sell it as "Duo", meaning that it comes with the 2 pedals axles. That's a little over my budget, so I was wondering ig anyone has tryied buying only the left pedal axle of the Favero Assioma Duo-Shi, and run it as a Favero Uno powermeter. I saw on some page that you can convert the normal "Duo" left pedal to a "uno" powermeter, but still, I would like to know if anyone has tried doing it on the Shimano version.
Hope I can get some info on this.
See ya!
