I've been searching through the forums for a while, and lurking on every speedhub thread I can find but I still have a question...
The Rohloff USA site recommends that a gear smaller than 2.4 times the rear cog is used. Why?
because the torque to the internal gearing would go beyond design parameters?
because the gear spread is such that anything less than a 2.4:1 ratio would result in unuseable low gears?
other reasons?
I'd like to use the smallest chainring/cog combination I can get away with (for clearance reasons) while still maintaining a sufficient level of chain wrap in the back.
