Whether because of age, arthritis, or whatever, a friend is no longer able to shift her Shimano 105 front derailler without considerable difficulty and some pain in her hands. Any ideas of a different shifter mechanism (even if not integrated with brakes) that might provide more mechanical advantage for shifting to larger chainrings? Ideally such mechanism would marry up with the existing Shimano 105 front derailler (new) and triple chainring.

If she has downtube bosses on her frame, a front downtube shifter is easier to operate than the STI. Down tube front shifters aren't indexed so any front Shimano downtube shifter will work.....Again this requires shift bosses on her frame. What kind of frame does she have?

Orbea diamond shaped down tube without bosses (unfortunately)

Would bare end shifters work?...

You could mount it in the bar end or on the top of the bar with a Paul Thumbie.
