Let's say for a given hill and my current lower gear I go at 3mph. If I reduce the chainring to 40T and go at speed <= 3mph, the torque on the IGH is not increased, right?
My goal is to keep the same cadence as now but to reduce the force on the pedals (that is, lower power and lower forward speed).
Does this make sense?
