Clicking Sound
Looks like there is a problem with my drivetrain.
I've been riding a Cannondale Synapse Carbon with DA, FSA cranks and Look Keo Carbon pedals.
A clicking sound has developped and is getting worse.
It only happens under torque when climbing. Could it be the crank? If so, what could be causing it?
Thanks!

It could be anything.
It only happens when climbing, which means it could be: Bottom bracket, cranks, pedals, chainstays, headtube, steertube, stem, or handlebars.
I had something similar once, it only happened when climbing, and I eventually narrowed it down to it only happening when torquing the handlebars + turning the steering axis right. Which meant I just had to tighten up the headset and compression plug.
So I would recommend trying to find out if its in the drive train or in the steering assembly first.

Also, as far a causes: You have a carbon bike, so it could be a crack in the frame, or a crack in the cranks, both of which would be very bad and could result in injury. Or it could be something as trivial as not enough (non-existant) grease on the pedal threads, or a loose bottom bracket or loose headset. Or it could even be a screw that isn't tightened down properly. There are probably a variety of other causes that I'm not thinking about right now

I had a clicking sound recently when I stood to pedal and accelerate. I also noticed I heard it when I made a quick, sharp course correction. Checked my chainrings, headset, derailleur hanger. No improvement.
Then I checked my quick release skewers for tightness. Gave the nuts a turn each and, viola! no more clicking.

It is amazing how the apparent location of an annoying sound can be from almost any location. I had a click from what I was sure from the R crank under pressure . Turned out, after exhaustive searching to be a crack in my LEFT cleat. Also had another sound that I was certain was from the front wheel- lubed the seat rail and voila, fixed.
