Note there isn't a provision for a chaintensioner on the RH dropout, it is therefore a single cog bike. (I'd prefer a sliding or swinging dropout here, as now you have no way of ensuring you start tensioning the front chain at the beginning of the adjustment of the excentric)

Rohloff OEM1, which makes it very OT ;) BTW who makes those dropouts?
