Abstract
The present invention is directed to a derailleur that can include: a base plate disposed between a perimeter of a drive sprocket nest and a pedal sprocket; a chain guide attached to said base plate for moving a chain laterally causing said chain to move from sprocket to sprocket in a sprocket nest; a chain guide surface included in said chain guide for causing said chain to contact over ½ a perimeter of said pedal sprocket decreasing the likelihood of the chain slipping off said sprocket; and, a tension member attached to said base plate for removing slack in a chain as the chain moves from a larger sprocket to a smaller sprocket.
