DOUBEL SERVO: SHIMANO's double servo-panta mechanism enables the rear derailleur to move in an optimum path. The guide pulley tracks the cogs closely while moving front to back, optimizing each shift. Perfect tracking contributes to the most accurate SIS shifting. Keeps rear derailleur guide pulley an optimum distance from each sprocket.
