I wanted to switch the levers so the right side shifts the front derailleur and the left shifts the rear derailleur. I don't know if it is possible to swap the ratcheting mechanism inside the levers or if I can order shifters this way.

If I can't do this I was considering putting a bar end shifter on the right side which would be easier for her. Any other suggestions would be appreciated.

Thanks, DB
