You’re right Vefer. I happened across the Sheldon Brown articles before I got the tandem. Read them all. They’re very good and helped me to feel confident to give it a go.
She’s enjoying it so far. Quite a learning curve for her as she’s never been a cyclist, even as a kid which must be rare. So I’m easing us into it as it’s easy to underestimate how bike fit I am compared to her. She’s slowly adapting to the saddle soreness business. She’s actually using two gel toppers at the moment but feeling less sore each ride. I may have to investigate different saddles at some point. She is suggesting rides we might do, so I might pull this off!
