Alright, so I'm stumped...

When I stand and hammer my bike (specialized epic) makes a tick sound on every downward stroke of the drive side crank.

My first though was, check the BB. Pulled crank and BB Nope... everything fine.

Second though was that it was from the frame flexing and maybe I had a suspension bushing going out... so I pulled the rear triangle... nope, everything is kosher.

Also checked the frame for cracks... nothing that I can see.

Any guesses?

Pull off the replaceable hanger and grease the interface. I'd also check the chainring bolts.

Check the headset, because usually when you're cranking down, you're also putting weight on the bars. Had a buddy whose ticking drove him nuts until the end of the season when he replaced his headset because the bearings were shot.

My ticking is virtually always my bottom bracket, though. Usually just needs to be tightened, or sometimes pulled out and re-greased.

could be a rogue length chainring bolt contacting your chainguide? i've had that happen before
Probably wouldn't be in exactly the same spot in my pedal stroke every time for a week straight though.

It makes the click, every down stroke on the drive side, without fail as long as I'm putting a fair amount of power down.

I may try pulling the chainring, and greasing where it contacts the spider and where the bolts contact the ring... it really does sound like it is that, but, like I said, that was the first thing I checked.

I was almost certain I was going to find a crack in the BB/pivot area when I took the rear triangle apart. It's exactly that kind of sound.

It would though. If its contact between the spider/chainring/cr bolt and the chainguide, it would occur in EXACTLY the same spot. I know this from misaligning a chainguide or 2 before.

I see what you're saying... I highly doubt that this is what it is as I can only get the tick when high torque is applied, but I'll check it tonight anyway.
my situation was the same. wouldn't happen unless i was really torquing. the clearance was close normally, but the bit of flex that occurred at high torque was enough to create contact.

also, refer to BV's suggestion.

are you using non single speed cranks? what chainguide are you using?

I had a similar issue... it was driving me crazy. Some rides it was there, others it wasn't. And I could never get it to happen when the bike was in the stand!

After checking everything multiple times I figured it out. The little plastic bit on the end of my SHOELACE was sticking out and hitting the crank arm or chainstay on every revolution.

Another cause might be your heel contacting a derailer cable and causing it to smack something.

LOL... it is the little things that can drive you crazy.

Reading comprehension- who needs it?

I was suggesting the main pivot, but sounds like you covered it!

Have you swapped out pedals, just to be sure?

edit: I'm having a hell of a time here, someone suggested it, but I think its good!

Ya know, whenever I have a glitch like this, I try and hear if it's coming from the front or back of the bike. Then I over-maintain that area.

Front? I tear the fork out, grease everything, re-install. Rear end? Same thing. Remove wheel, derailleur, brakes, grease and rebuild. Same thing with your cranks. Whatever it is, it goes away every time. Trying to pinpoint little things like that can take forever...

Or like someone else said, start riding with tunes...

if you checked all these suggestions already could it just be the beginning of the end of your chain? your chain could start to creek very slightly as it starts to fatigue until it starts to creek for at least half of your crank revolution. That's how mine sounds right now!

we had one bike in the shop the other day who had shimano cranks and the crank was starting to come loose from the spindle. it wasnt enough to where you could feel it move but you could hear it when you really cranked on it. im sure the chances of it being that are slim to none but check it out anyways. unfortunately if it is that then there isnt much you can do

Recheck the chainring bolts. Had the same problem once, pulled the whole drive train off twice. When I was going through everything one of the chain ring bolts turned another 1/4 turn and the sound disappeared.

Yes these are non SS cranks, Raceface Deus with an E13 chainguide.

As for BVs idea... The HS actually IS shot, I've been waiting on a new upper bearing assembly, which came in yesterday. THough I doubt it's the cause of this... I can hear where the sound is coming from... and it's definitely not from the cockpit.

Last time I had a phantom creek like this I tore the whole bike down and re-lubed/tightened everything I could think of. The sound persisted for another few days until I figured out that I had some dead bearings in my pedal.

I've had a ticking noise as well, ALWAYS in the same place when I pedaled. It was also my shoelace clicking on my frame/downtube. Tuck your shoelaces into your shoe on your next ride and see what happens.

I knew I was missing something... I need to get some shoe laces!

:D

I actually removed the ring last night and greased the interface between ring and spider, and replaced the chainring bolts with some nice red ano bolts that I was saving for when I had to replace the ring itself.

Also replaced the badly corroded cartridge bearing that had welded itself into my headtube (bike is still fairly new). What a mess that was. Best part is that I bought the only red ano campy style headset I could find, and it came with upper and lower identical bearings. So since my lower bearing is a 1.5 and it's in good shape, I now have a replacement bearing for the time that this one breaks down from my incredible sweat waterfall.
