click click click...

it's coming from my crank area, it clicks everytime my right leg hits nearly 12 o clock and when I do track stands/ backward circles so around 9 o clock with again my right leg. I can feel the click in my right foot (i dont ride cleats). I ride a mid 2000's bianchi pista with dura ace cranks and sugino 75 chainring. the clicking began about 5 days ago. first thing I did was loosen and retighten everything down including crank arms, pedals, chainring bolts, and even the seat post clamp/seat itself. So I came to the conclusion it must be a bottom bracket issue and I put it into the hands of the lbs. Results came back as nada. The only thing I can think of is the slight bend in the chainring, but I don't see how this could cause the click nearly every pedal revolution. I have never had problems with this bike until now. Any ideas?

At 12 o clock?? Check if your shifter cable is hitting the crank arm.

No shifter cable its a track bike, I doubt its the bb, my mechanic said its in good condition, its gotta be the bent ring making a tick noise as the chain runs across it

Here's an easy way to diagnose or eliminate the chainring as being the cause.

Remove the chain, clean the chainring, then use a dry marker to color the tops of the teeth. Put the chain back on and ride a short while. Then turn the crank and check to see if one or two teeth have the color buffed off before the others. If so, odds that that the chain is clicking as it engages that tooth. Fix it by spinningh the crank with a file against the teeth to take off the high spot.

Any chance your crank arms are bumping against a kickstand?

could be a pedal bearing. try different pedals and see if the sound still persists.
