Why We Like The Shimano 105 ST-R7170 Di2 Shift/Hydraulic Brake Lever

Shimano's new 105 ST-R7170 Di2 Shift/Hydraulic Brake lever lets us get on board with Shimano’s time-tested wireless shifting without breaking the bank. The 105 Di2 lever takes ergonomic and aerodynamic cues from the Dura-Ace shifter to provide a comfortable hand position that slices through the wind effortlessly. Wireless Di2 technology pairs Shimano’s ultra-reliable shifting with a lightning-fast response for when things get hairy in the peloton. Plus we no longer have to search for a place to charge everything since this lever is powered off of two long-lasting coin batteries.


  • Wireless Di2 right/rear shift/brake lever for use with hydraulic brakes
  • Two easy-to-find CR1632 coin batteries power the levers
  • 16.4mm reach adjust lets us quickly find our ideal hand position
  • Quick battery level checks using the light on the front of the lever
  • Aero and ergonomic hoods allow for a comfortable, performance-oriented position
