Shimano Ultegra Di2 6770 Shift/Brake Lever Set

Shimano Ultegra Di2 has forever changed the way we look at drivetrain technology. Cables are going the way of the steel frame. With shifting this good, Ultegra Di2 may be the new benchmark for price and performance among drivetrain components. Shimano did their homework too. The Ultegra Di2 Shift/Brake Levers share the same profile as their Dura Ace brethren, making a supremely comfortable perch for your palms.

Concerning shifting, this is where the magic happens. The 6770 Di2 shifters take Shimano's signature light action shifting to the next level. No more heavy handed antics are required to drag a steel cable through housing before overcoming the force of the loaded derailleur spring to initiate a shift. With a click resembling that of a computer mouse, the Ultegra 6770 shifters send a signal to the derailleurs to make a shift that is far more forceful and precise than any human hand could accomplish.

Remember the old days when you had to connect steel cables between the shifter and derailleurs and then stretch them before tuning them to the proper tension? How quaint.
