    The front derailleur, however, switches gears almost 30% faster than Dura-Ace’s mechanical counterpart. [1] On traditional bikes, the front derailleur is problematic because the chain can be under tension and has to make a large vertical jump between chainrings. The electronic system's controlled motion overcomes these problems.
