I built this Trek 930 for my wife, and she has similar issues as your wife with regard to flexibility and the need for a more-upright riding posture. I worked with her every single time we took a ride, asking how her legs felt, back, seat position, handlebars, etc, until we got it dialed in just right for her.





This is last year's pic. It now sports an SQ Labs saddle. We had quite a time finding one that fit her well and didn't cause numbness "down below." I finally had her do the SQ Labs sitbone measurement and we selected the proper seat for her. Now she can ride for miles and miles in comfort and security. I know this isnt a Troll, and I'm a Surly nut myself, but this might give you some ideas.
