Bike is a mid 80s Miyata with early Shimano 105 components. It's a 10 speed, 5 speed cog and 2 chain rings.
I recently had my front derailleur set up again by a good mechanic after it stopped shifting at all. He reinstalled the derailleur to height/angle, adjusted the limits, and installed a new cable. It shifted great for a few days, super fluid and quick. Now it has trouble traveling far enough to reach the larger chain ring and I feel like the shift cable stretched a bit and needs to be re-tensioned.
Is it likely the shift cable needs to be re-tensioned? Or the limits need to be readjusted?
