I'm not sure what you mean how do I start?
I typically shift about 2 or 3 gears before I stop so I can start up easy. As I build speed, I click down about that many gears.
At a stop I usually have my left foot in the pedal and the right one on the ground. Right before I go, I pull the pedal to where it's just forward of the 12 oclock position. Right foot will be on the pedal once I'm moving but I won't attempt to flip it over to get it inside until maybe 2 or 3 full cranks later.
