I have no idea what can be.
The sound seems came from the pedal.
Already greased the axle, inspected the cleats, inspected the crank, the crank bolts etc.

In less than 6 months I'm very disappointed regarding those pedals. Keywin were a lot better in many different pow

i had the same thing! my click was a little more pronounced at times, more a single click although occasionally it became a little double click. it was always once per pedal revolution, typically with the left foot forward and up, and only under fairly decent load. drove me CRAZY climbing. replaced many things trying to fix it, even replaced the pedals under warranty for side to side play. (wahoo was very cooperative.)

i was convinced it was in the BB, but one day about 50 miles into a 70 mile ride, i unclipped at a light and when i reclipped the sound was gone. when i got home i removed both pedals, thoroughly cleaned the threads on the cranks and the pedals, greased, reinstalled exactly to torque spec, and they have been silent for several thousand miles.

I had to try this too, tomorrow I'll write down if the clicks ate still there.

Also for any SP pedals make sure the cleats are mounted fairly flush with the sole of the shoe so that there is no/very little bowing in the cleat when screwed down. Use shims to get it right. Bowed cleats can cause a few different problems.

i can't belive it.
this sound so stupid, i have no idea how the treads will make the sound. But somehow a little layer of grease fixed the problem...

trust me, i felt incredibly stupid too!

i had replaced the pedals with brand new ones, new chain, new cassette, new cleats, thorough creak chase by the shop, was about to get upset at them (it’s a pretty new bike) and insist they tear apart the BB…. and it’s solved by grease and reinstall the pedals!!! nuts. i would love to know what it really is. sounded very very similar to yours.

My tip, if it's practical for anyone, is to carry a small squeeze bottle of lube with you stowed away. When the click/creak comes, apply the lube to the suspecting cleat. It has been beneficial during my rides. Sucks that the design has a flaw, but the overall design I like.
