BB Mount TOP SWING FD The wide pivot link design boosts strength and rigidity. Flex is suppressed, creating sharp, precise shifts that are faster and smoother, even from low to high gears off of the saddle. Also, Shimano uses a Double Servo-Panta Mechanism which keeps the guide pulley close to each sprocket to allow for smooth and precise shifting you've come to expect with Shimano.
