Well to best explain it, if you look where your track is actually driven off of a shaft you can see that you have two drivers that grab the little nubs sticking up out of the track and thats what allows the track to begin to move. An extrovert driver is kind of close to the same thing except for that the driver "nubs" actually go through the windows on the track(must have a track that all windows are open) This makes it so that when your track is loosened up there is practically no chance of ratcheting. The looser the track, less rolling resistance.
