Mechanical Problem
Recently I've experienced a clicking noise on the drive side up around the crank. It started out without any noise, just something I could feel toward the top of the upstroke on the drive side pedal. Lately it is a clicking noise and it occurs more often when under more pressure such as going up a slight incline, not so much on the flat.
I checked to see if maybe the pedal was loose but it seems to be ok. I'm thinking it could be in the bottom bracket or maybe something in or near the derailleur being transferred to the crank. Or maybe the crank itself. I cannot seem to re-create the noise while the bike is on the stand.
Has anyone had a similar issue or have any ideas on what might be causing it?
Thanks

Barring The usual of Pedal bearings and bottom bracket- Look at the sprockets. Does it occur in only one chain ring?
Then there are other body related causes as your weight shifts such as a Loose saddle or seat post related problem.
If it is always in the same pedal position it could be any of the above and I doubt it would be Dérailleur or chain related unless the chain is worn and has damage to it throughout the length and as you put power on at that part of the pedal stroke it clicks.

I have the same clicking:
Replaced Bottom Bracket, Pedals, Chain Ring's, Chain, Seat Post and Saddle, Rear Wheel and Cassette.
Can find No Cracks in the frame.
Still have the noise.
Good luck.

There's a 'debugging weird noises' link over in the maintenance section of the forums, you might try that.
If your cleats (on you shoes) are adjustable, it could also be that.
I had (have, sometimes) a random squeek that is pedal / crank / cleat related - I stopped by the LBS and the mechanic
there gave me a quick list of 4-5 things to check to help isolate the issue.
and of course YMMV.

My mechanic says to change the crank arm as the spider is pressed on.
We are going to put the bike on a trainer and try to find the noise with that method.
I use walking shoes.

The bike and the bottom bracket are only 4 months old. Could the bottom bracket wear that fast? This is a bike I built and I'm sure the bottom bracket is secured properly. Also the noise started out sporadic and has gotten worse over time. I'm concerned that 10 wheels replaced a bunch of components and still has the noise. Maybe I will replace the bottom bracket this winter since that worked for Rick@ocrr.

Tim, you could have a slightly cracked or separating pedal with no sign of play unless you really manhandle it. Same with the BB; it will usually be at least a bit loose if there is anything wrong with the bearings, but you might have to exert a lot of force to notice anything if the problem is not too severe. With either a busted pedal or a spent BB, you're certainly going to feel it more when climbing.
10 Wheels, with everything you replaced, seems you've eliminated any possible culprit on the bike. Have you checked your feet? No joke, had a similar problem myself once: after dismounting from my rickety steed and taking off my shoes, noticed a clicking sound eminating from down below with every step I took — That problem eventually resolved itself but my pedals were still shot.

I Wear Rockport walking shoes, nothing to click.
Mine clicks three times when I stand to pedal in any chain ring.
I ride with my mechanic 4 times week.
We will find it.

I had a very similar noise recently and could have sworn it was in the bottom bracket or pedal. It was actually coming from the hub in the rear wheel. Tightened the hub a little and the noise went away.
I've also had a similar noise while climbing at low speeds due to cracked rims at a nipple.

When you say you feel it at the top of the stroke, do you mean that the crank side arm somewhere between the 10 and 12 o'clock position?
This may or may not be it, but I had a similar thing last summer that drove me nuts for a few weeks. It turns out my crank arm was hitting the front derailleur cable. It didn't do it on every stroke, only when there was enough torque to flex the bike frame ever so little.

We had a similar problem on our tandem. We thought it was the bottom bracket (under the stoker). We could not recreate the noise on the stand. It was actually the captain's seatpost. A bit of grease on the post...problem gone.

All good suggestions. Usually is a slightly loos bolt/nut somewhere. I have also had clicking from the Stem and handlebar interface that only clicked when loaded a certain way.

My noise turned out to be a less than very tight skewer although we did R&R a brand new BB. Go figure. Seat post is also a common source. Very hard to tell where these noises are actually coming from.

A number of you have referenced the seat or seat post. I don't understand how that could translate into a click that I can feel and sometimes hear in the area of the drive side pedal?
Bill, the BB is an ultegra 6700, English.

I help out in a LBS and write the jobs up for the workshop. I am now very careful NOT to indicate to the mechanics where the rider thinks the sound is coming from.
Various clicks and knocks "from the bottom bracket" frequently are found to be coming from elsewhere including, handlebar, stem, headset bearings, loose wheels, broken spokes, seat-pins, saddles, cracks in the frame, sloppy cables, loose cleats, broken shoes, pedals, chain-wheels, worn chains, cassettes, freehubs and just about anything else, including, of course, the cranks and bottom bracket bearings. Frames, particularly crabon fibre ones, do a great job of transmitting noise and clunks around.

1. My whole saddle on my Spec RH squeaks - took me quite a bit of time to figure it out. It still squeaks, but at least I know what it is!! I have yet to figure out exactly why.
2. I have had a funny noise on my utility road bike for some time, which I could not duplicate on the stand. Turns out the wire from the pickup to the odometer was rubbing, but ONLY when the bike would flex on turns so the wire would come in contact with the top of the wheel. I thought my entire wheel would need rebuilding.

That saddle/Seat post creak can appear anywhere on the bike when you are riding it. Often mistaken for crank noise because as you pedal- weight is transferred from the pedals to your body and it can be the weight shift on the saddle that makes you think the noise is crank related.
First things I check are for loose BB- Pedal noise from the bearings and then saddle. After that it is down to observation and elimination.

Tim, I had a similar problem. It turned out that the rear axle was broken. The quick release applied enough pressure to keep the two halves together but they creaked just slightly when loaded for climbing, etc.
Good luck.

I'll bet it's a carbon fiber frame. As was pointed out somewhere above, carbon fiber frames are great at transmitting the smallest noises. You can have dust in your pedal bearings, and the frame will pick that up as a click.
I'm riding a steel frame, and all errant noises can be easily traced. When I was riding the carbon fiber Trek, I'd get all sorts of untraceable sounds.
