Again, I am NOT an expert on this subject......yet. Please determine your needs and do your own calculations before you make a decision.

Actually, using the JVN Design Calculator, the overall reduction should be between 15:1 and 7:1 so gearing down off the gearbox about 2:1 should result in those ratios which would be a good all around performing drivetrain!
