Friends,
I am not a bike mechanic... just a simple dude who wants to get from point A to point B. I have a fairly new Trek 3500 which I bought a few months ago and already brought in for its free tune-up. Soon after the tune-up, the front derailleur started clicking, quietly, every time I push down on the left pedal.

I brought the thing in yesterday and paid $10 for the guy to fiddle around with the front derailleur a little bit, and rode out of the shop. It was quiet for a few minutes and then the clicking started again, exactly the same as it was before.

Anyone have a suggestion as to what to do next?

I can bring it back but I'm concerned about bringing it back, watching them fiddle with it again, riding, hearing the clicking sound again, and going around and around with this for a while without a real solution...

BTW I live in North Miami (Aventura) and my LBS is called City Bikes

Thanks

Maybe the cage of the FD is bent a bit outwards. When you push your left crank, the right crank rises up and it might hit/rub on the FD cage.

Does it click when you are on small chainring?

Other periodic clicks at same spot may be a chipped raceway in the bottom bracket, or in the pedals. At each revolution you exert pressure in same chipped area and a ball nearby will click into it.

But check that you have space between right crank and front derailleur when is at outmost position (big ring, FD resting on the limiting screw)

If you want something done right, do it yourself. Derailleur adjustments are an ongoing maintenance procedure and are not difficult if you approach it systematically. Fiddling is not a systematic approach. Here is a good guide, follow it from the beginning step by step without skipping any: https://www.parktool.com/blog/repair-...ur-adjustments You'll need to adjust the rear at some point, here's that one, too: https://www.parktool.com/blog/repair-...nts-derailleur

How loud is the click? I had a slight click that I could barely hear while riding on my bike, when the left pedal was at 6 o'clock position. Turned out to be the cable on the derailleur getting hit by the pedal crank as it hit about 12 o'clockish. (I'm not great with the terminology as I'm pretty new myself, sorry.) Fix for me was to bend it out of the way a bit. (and by that I mean the cable itself, not the derailleur!)

That's what I was thinking too.
