I'm experiencing clicking noises when I put pressure on the pedals (either side). The bike is a CAAD12 105 (it has FSA chainrings).
I've done some investigation to pinpoint the source of the clicking. I'm able to isolate the problem by standing on the crank arm (not pedal) while the front wheel is being held perpendicular to a wall. This isolates stem, handlebar, saddle, and pedals.
Of course it could still be spokes, fork, frame, or drivetrain. But I made a discovery: when I release pressure from the crank arm, there's a corresponding click. Moreover, if I remove the pressure slowly the click doesn't occur unless I press the inner and outer chainrings together with my fingers afterwards.
This leads me to the conclusion that the noise is coming from the chainring/bolt/spider interface. I have removed, lubricated and torqued the bolts back (12nm as specified by FSA). But the clicking persists.
