Front derailleur adjustment help
Shimano 600 FD with DT shifters on my Centurion. When I'm in the big chain ring after a minute or two I start to get chain rub. I can trim the shifter and then I can pedal smooth with no noise but after another minute or two I need to trim it again. So basically seems like the lever is moving on it's own/not staying in one place. Is my cable tension too tight? Is this a limit adjustment? Is this just nature of the beast with friction shifters?

Your friction shifters don't have enough friction. There is usually an adjustment screw to increase the friction

Tighten the attachment screws that hold it onto the downtube clamp. Most (if not all) have a keyring knob on the screw itself so you can tighten it without tools.

Thanks for the responses. I tightened the screw on the shifter. First bike with DT shifters so I didn't even know that was an adjustment point
