Any ideas or anyone had /have the same issue?
It's on a Carbon frame BTW.
Rick - nope it's english 68mm
1. Check to see if the derailleur is hitting th crank arm. This would depend on the gear you are in. Does it happen in every gear?
2 .Are you sure it's the crank and not the pedal doing this? If you have a different set of pedals try a different set.
3. Ensure that the chain links are not binding.
4. Is it the BB? Try a different BB.
5. Are the chain ring bolts torqued correctly?

If so, read my comments in this thread
Interested in this, as my bike clicks when I am out of the saddle peddaling, it clicks when my right crank arm is going forward (from 12 o'clock to 3 o'clock) and stops when I sit back down.
I have taken apart and cleaned and regreased everything and then put back together and it's still there, it's not BB30 and I am using a Campag 10 speed UT carbon chainset with campag BB cups, but AM using the wave washer, did you take yours out and it stopped?
Sorry for the hijax but the click is driving me crazy.
I'll be keeping a close eye on this thread.
I've had annoying clicks on cranks from alu bolts in the past.
You can try swapping out to heavier bolts or try adding chain ring bolt washers to change the interface between metal surfaces.
If everything is 100% clean and there is no question of debris or dirt allowing play between rings / spider faces, try adding copper slip very lightly on the contact point between c/ring & spider to address any contact point interface which might be causing the noise.
Usual vouch for these clicks is whether the chain & chain rings are new or not... if the are not new or you have a mis-match of wear you may get some clicks coming from the chain as it engages / disengages on the chain ring teeth unevenly.. generally wet chain lube helps to iron out chain / chainring interface noise better than dry lube will as well.
but AM using the wave washer, did you take yours out and it stopped?
Yes, it has stopped and stayed gone. But I substituted enough flat washers to take up any left over space on the spindle, as described in the linked thread. IMO a wave washer is just a silly idea. But what do I know ? (I am a merchanical engineer, so maybe that gives me some credibility)
