What could be causing a clicking in the crank area while under power?

It seems to only happen on the downstroke of my right pedal while climbing out of the saddle, or if I pedal extra hard on flat terrain. So far have tightened pedals, chainring bolts, removed and reinstalled crank, taken bash guard off (the chainring spider was coming very close to contacting the chainguide, and I thought putting the pedals under power could have flexed enough to contact, but that was not the case), and still nothing has changed. I don't think it's suspension related because I never hear it without pedaling, and like I said it is rhythmic with the downstroke of the right pedal

I think my next move will be to take apart my pedal spindle and see if there's anything wrong with it, but needing suggestions for what else it could be

Bottom bracket bearings.

They seem to spin pretty smoothly with the cranks out, I'll have to take a more in-depth look at them

Anyone find blackspire oval chainrings feel and sound like crap for the first ten rides? My race face rings always feel smooth when I put on a new drivetrain. When I replace my drivetrain with blackspire chianring, it is grindy and rough feeling/sounding. I note that the blackspire seems to have a more aggressive oval, I assume that has something to do with it?

Sram Code RSC or Shimano XTR, opinions?

Code.

I don't like throwing away whole caliper or lever assemblies when they need to be rebuilt.

I second the Code. Rebuildable with better lever feel.

Strange thing to say seeing as the question was about codes or xtrs.

I have codes currently (they came on my last bike) and theyre fine. However they are Sram so i'm expecting them to shit the bed at some point. I'd expect better reliability from shimano in general, but as has been pointed out, spare parts are not available.

It may be the pedal bearing, it is is worn then the balls can jam slightly under load. Does the RH one fell smooth if you spin it?
Is it loose or can you feel a slight tight spot?
Sometimes just the fact the bearing is slightly worn or can give enough play.

It's probably pedal bearings, my stamps did that a while ago

code
Depends on your technique and skill level, and preferences for feel. Xtr have much more initial bite, if you are a precise skilled operator some prefer this. I however find the modulation of the code rsc to help control my bike through over braking (oh sh!t moments and poor technique) and find I skid much less and can go faster on the codes.
