Shimano Ultegra 6770 Di2 STI Levers

Features:

• With Di2 technology shifting is easy and precise - just a light touch, as soft as a mouse click, is sufficient for the front or rear derailleur to instantaneously select the correct gear
• The removal of traditional mechanical cables in favour of electrical wires eliminates poor shifting caused by contaminates, corrosion and stretching, and also provides effortless gear shifts
• Simply pressing tactile buttons allows effortless and comfortable shifting even when your hands are cold
• Buttons are located in a near identical place to the positions you'd assume for shifting using a mechanical Shimano STI
• Brake lever pivot is positioned to be used with super SLR brake callipers, increase power providing excellent ergonomics when riding on the hoods
• Finely tuneable reach adjusters for the levers enable custom fitment for all hands
• Levers are supplied without electrical cables, as these need to be ordered separately to suit
• Weight is 313 grams a pair
• 10 or 11 Speed
