The Schlumpf Mountain drive is 1: 2.5 so the two-chainring equivalent might be 54/22. Does the tensioner even have the capacity for that much chain wrap? The Schlumpf is best used with the BSR rather than the BWR to avoid gear duplication. The old Sachs 3x2 6-speeds worked well with the Schlumpf using a 54t chainring which gave you 12 evenly-spaced gears and no overlap (you could use up to 60t, IIRC, but you lose practical low-end gears that way.) They are heavier than a two ring (without a FD).
