New Bike make noise only when pedalling

Hi to All of You,
The problem is when pedalling also only when there is resistant, (I mean that when turning the front chain wheel is all Ok.) hear a noise. Mostly when the left pedal at 7 if it is a clock. The pedal changed to try with other so it is not.
In June I bought a new bike, The wheel is SD Swiss. The front chain wheel, (the lager is Hollowtech II) and all the front and back changer are Shimano 105. The bike made about 700 lm but the noise from the beginning. Took back to the shop but they told that not find nothing in the front lager.

Have you idea what can be???
Thanks.

..Thanks, The noise is like "ssk". just like that. Not feel any resistence or shaking. The worst I can not tell from where exactly comes. What is sure that the curble at each time on the same position as I wrote earlier.
Interesting is the noise happen only when I pedalling also with the left side pedal. If I pedalling with the right side and not make any force on the left pedal no noise happening.
I will try to record the noise with the mp3 recorder. Will put it near to the back wheel, after near to front wheel and after to the crank set and will see where is stronger and can analyze the noise.

Well, do you have anything like an extra rear wheel and pedals.. Those are easy to swap out and if the noise persists, you can rule those out. Bottom brackets are also a source of noise. If it is old and/or high milage, then swap it out. If the BB is relatively new, try removing it and using some Teflon pipe tape around the threads and then reinstall it.

Other things to check...Tightness of your chain-ring bolts and crank arms. Sometimes removing them and applying a little grease can make a big difference.

Another source of noise when pedaling, is the saddle. Check the saddle for tightness. A quick way to rule this out is to stand up and pedal. If the noise persists, then you can rule it out.

Try this stuff first and see if you can isolate your problem.

Hi bicycleflyer,
Thanks a lot.
The pedal changed and the problem not there. Because this is a new racing bike (with flat handlebars) not easy for me find wheel. The bottom bracket is also a new Hollowtec II for Shimano 105. As I read if I take off can easily demage a part and can not set back. Saddle checked. Chain-ring bolts will check.
Preparing for sound record.

Are the shoes rubbing against the crank?

The best way to identify the problem is note when the noise occurs. Everytime the wheels go around? Everytime the pedals go around? Or everytime the chain goes around? Your problem is everytime the pedals go around

Checkout this page. https://www.sheldonbrown.com/creaks.html

So if I understand correctly the noise is coming from the left side every pedal revolution, but only when putting pressure of the left pedal? Could be the crank bolt or the stack bolts. Just try to check everything off the list from the Sheldon Brown link. Helps me everytime. Good luck.

Noises like this can be difficult to diagnose in person.

Pretty much impossible on the internet. Sorry, just how it is.
