I have a 3sp KHS Green. From what I understand the rear sproket has 18 teeth, and if I wish to have a higher (or is it lower?) gearing (going faster with the same rpm) , I need to change out the sprocket for one with fewer teeth. The front crankset has 32 teeth, if I'm reading the specs right.
What I like to achieve is that what currently is my second gear, would become my first gear, and all subsequent gears are higher. Using Sheldon Browns calculator, it looks like I need to switch from 18 teeth to 13 teeth.
Does that sound right, or am I understanding that wrong. Are 13 teeth going to be way to hard? Any thoughts?
Thanks in advance.
