Down stroke double clicking noise
Hi, when i first got my bike it was great. Now i'm having a problem with it and i cannot figure out whats the cause.
*Only happens with RIGHT crankarm
*Only happens on the small chainring
*I believe it happens on all the cogs
*Happens out of the saddle
*Happens when the right angle is at around a 60 degree and i put pressure down.
*My cleats are not the cause because i tried it with regular shoes at a 60* degree angle and put pressure and it clicked, i lifted my foot and it clicked again.
*It's a BB 68 pressfit
*Fuji Altamira 2.0
*Ultegra 6800
Should i buy a new bottom bracket? I don't believe it's the BB because it only happens on the small chainring. I also dont think its my bike? Or seatpost because i tried it with regular shoes, holding the brakes and it made the clicking sound without me sitting on the saddle.

Clicks, creaks, and chirps are incredibly hard to diagnose, even when working on the bike. Noises can happen in one area of the bike, then resonate and sound like they come from a completely different area.
If the bike is pretty new, I would take it back to the shop you bought it from and tell them what's going on. A good general tightening of all bolts and threaded joints might eliminate the problem. If not, disassemble, clean, and reassemble every threaded joint you can see.

I have a 5nm torqkey that i use on mostly everything. Not sure if that is to low for some parts though. I will disassemble what i can and re-grease it though. I bought the frame/fork(with the BB) used and everything else on the bike is brand new. I had an ex mechanic assemble it for me about 9 months ago, the bike was quiet and well then.

Do the easy things first. I would suggest that you try another set of pedals, platform type if you can find/borrow some. Thoroughly clean and grease the threads and mating faces and tighten them firmly. This will help eliminate the pedals and cleats from your list of possible trouble spots. Do the same with your pedals when you reinstall them.
The chainring fasteners are another often-overlooked source of noise. Remove, clean thoroughly and grease the threads only and reinstall them correctly.
Check the cassette lockring torque and that it is clamping the cassette properly. Then start the more difficult tasks.

Ds mentioned the chainring fasteners, which makes the most logical sense, but you have not addressed that possibility. The cassette (and chain) of course cannot be involved at all - they don't rotate at the same rate as the cranks.

I tried a platform pedal and it still make the sound when it's in the small chainring. The sound is coming from either the crank, BB, or frame Bb shell. I also tried tightening the cassette a while back but it still made the noise. I'm probably gonna take it to a shop and see if they can try a new crank, or BB since I don't have an extra one. I'll keep you guys updated. Thank you.

One bike I had made a strong creak-click with every pedal stroke. I removed the bottom bracket, greased the threads, then reinstalled the BB. The noise went away, but soon reappeared. I did this twice before reinstalling the BB with a couple wraps of white teflon "plumbers" tape around the threads. No noise since. I guess that the frame's threads are a bit larger than standard, which means the BB wiggles no matter what. The teflon tape removes the wiggle.
Also thanks everyone that helpped. Sorry about the late update
