Pedal Knock when at certain power
Any suggestions are welcome. I have developed a silent knock (there's not actual sound) or thunk feeling in my right pedal when applying something over 200watts or what not of power. Wish I could describe it better, but that's all I've got. The pedals are Favero Assioma Duo Side Pedal that I've had for just over a year. Minimal outdoor wear as I've primarily used them on an indoor setup, but some outdoor work.
Is this a pedal bearing issue or should I look at something else?

Do the easy and cheap things first. Adjust and grease pedal bearings if possible. Swap the pedals with a known-quiet set, preferably platform type to rule out shoe/cleat noise. Clean and grease both male and female threads and torque firmly. Check that your bottom bracket fasteners and chain ring bolts/nuts are secure. Clean the mating surfaces and grease the chain ring bolt threads.

It always seems to be my right pedal too when that happens. But I'm only using Shimano PD-A520's. Yes you might just need to disassemble, clean and grease them.
But you probably should make certain that is what it is. Swap pedals is generally easiest, or move these to another bike if you don't have extra pedals but for some strange reason have an extra bike! <grin>

Thanks all. Pedal disassembly, clean and grease seems to have done the trick. Add another new maintenance experience to my bucket, and wasn't all that hard.
