Bringing your brakes, gearing and overall control back into hand, mounted up at the end of your base bar, the Shimano ST-R9160 Dura-Ace Di2, STI for TT / Triathlon, left hand double keeps you equipped to power that rear brake and affect your gear shifts with the deftest of touches.

Offering complete control over your front Di2 derailleur, this left-hand shifter is operated easily at the simple touch of a button. Making use of available separately E-Tube electric cabling, this lever ensures you of a perfect shift by reducing your dependency on wires, which themselves are susceptible to corrosion, stretching and contamination.

The brake blade ergonomically designed to neatly fit the profile of the hand, the pivot is positioned to be used with super SLR brake calipers, and offers space enough for use with hydraulic setups.
