 Shimano Dura-Ace FD-7970-F Digital Front Derailleur

Smooth front gear changing with instant reaction and perfect precision thanks to highly innovative digital technology. The front derailleur is the "brains" of the system. The integrated ultra-compact CPU not only ensures that shifting is perfect for both the front and rear derailleurs individually, but also by monitoring the position of each, creates a front derailleur that tracks the chain and requires zero manual trim without sacrificing any shifting speed. The front derailleur logic also performs the inward shift from the big chainring in two parts to eliminate chain drop, with both actions measured in fractions of a second.
