Hi all
So I bought a beauty of a road bike a month ago.
Here it is

Did 1000 kms in a month. From day one I noticed a clicky noise that came from the left pedal/crankshaft/crank.
This continues to this day especially when I press down hard on the downstroke of the left pedal. Been to my LBS several times. They've cleaned out the pedals, the bottom crank and every thing they could think of. After they tweak with it a little bit it gets better for a while but soon returns. The bike is doing great apart from this.

I am sure with all the decades of experience out there you guys can help!
