Shimano Ultegra Di2 R8150 12 Speed STI Levers

Shimano's ST-R8150 Ultegra Rim Brake Di2 STI Shift Levers for Drop Bar deliver precise shifting. A new hood design provides riders with better grip, while still giving easy access to the shift lever in the drops

- 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

- 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

- Servo Wave 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

- Wired connection to the front and rear derailleurs with SD300 series wires
