Road Bike is making noise when pedaling at the same roation butnot every time.

The sound is a lot like the clicking noise I have heard on other peoples handle bars (especially when they are climbing)

Note: I recently changed my cogs, adjusted saddle a bit more forward, and lowered handlebars a bit. I have stood up and pedaled while still hearing the noise, I have ridden with no hands and still heard the noise. I have changed to lowest and highest gears and still heard the noise. I only hear the noise when I pedal and I flipped the bike upside-down and pedal it with my hands and hear no noise.

I've been noticing a sound similar to a click noise. It just happens once every rotation.... But it doesn't happen all the time. For example -I can ride and hear it click 20 times in a row every time my left foot is nearly fully extended. But I can keep riding and later do 20 rotations in total silence. (It's not my shoe lace or anything hitting the frame)

I thought perhaps it could be the bottom bracket but I don't notice any roughness when I pedal. I bought the bike new about 2 and a half years ago although I ride it everyday (probably 150 miles a week on average). It is $300 bike from bikes direct. I haven't noticed this noise up until a few weeks ago.

Any ideas? I tried tightening the big chain-ring and it was already tight and has no bend/wobble.

Mine does the same thing, no clue why. 1979 Raleigh here and about the only original part on the bike os the frame and front derailleur.

Check to be sure that the end of the front derailleur cable or a shoelace tip is not tapping a crank arm as it goes around. Also check the kickstand (if present) to be sure it is not hitting a crank.

Pedal bearing or a worn shoe cleat comes to mind. Sometimes when I have a click like that, I just tear down the whole bike and put it back together regreasing and readjusting everything. Its good to do that on occasion. You find small things that need attention. Clean up the chain, get the gunk out of the cassette and derailleurs, that kind of stuff.

Dry pedal threads where the spindle screws into the crank arm, maybe? Try taking off your pedals, greasing the threads on the spindles, and reinstalling.

Guessing is next to useless - too many possibilities. You both need to adopt a logical approach, looking at the most likely/common causes 1st (ex: improperly tightened crank arms or pedals. Creaks, Clicks & Clunks

Don't tell me what "should" be - either it is, it isn't, or do something about it.

If you think I'm being blunt take it as a compliment - if I thought you were too weak to handle the truth or a strong opinion I would not bother.

Please respect others by taking the time to post clearly so we can answer quickly. All lowercase and multiple typos makes for a hard read. Thanks!
