ST-R8050 Ultegra Di2 STI for drop bar without E-tube wires, left hand

• 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
• Full and semi synchronized shifting programable, Synchro shift compatible meaning a single shifter can control both front and rear shifting which can be fully custom tuned to your riding preferences. Semi synchronized shifting means when a front shift is made the rear mech will automatically correct to the appropriate ratio
• Simply pressing tactile buttons allows effortless and comfortable shifting even when your hands are cold
• Drop bar STI with shift buttons located in a near identical place to the positions you’d assume shifting using a mechanical Shimano STI
• Programmable function of top button remote switch for third party cycle computers
• 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
• For use with E-tube electric cables
