What an interesting discussion about gear ratios, torque and such matters last night, with jiberjaber disproving a point about torque using advanced maths written out on the back of a scrap of paper.
As a follow-up question to those present, in a single speed setup, if the freewheel is 1/8 and the chain is 1/8, does it matter if the chainring is 3/32 with a wide/narrow tooth profile?
