Hi, I've recently ordered a Superdelite with Vario gearing and GX option. My plan is to use the bike for 50% touring and 50% mountain biking (on some steep fire roads/trails -- nothing particularly technical (but steep grade)). I'm wondering how well the Vario can handle steep fireroads/trails -- whether the Rohloff would present a significant difference over the Vario that a little extra muscle on the Vario can't handle. I'm also wondering whether the recently announced firmware update to the Bosch motor might help to mitigate the difference. Would greatly appreciate advice, since perhaps it's not too late to change my order.
