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

Shimano's new 105 ST-R7170 Di2 Shift/Hydraulic Brake lever gets us up to speed with Shimano's time-tested Di2 system, in a more wallet-friendly package. The 105 Di2 lever utilizes the ergonomics and aerodynamics of the Dura-Ace shifter to encourage a comfortable hand position and slice through the wind. Wireless Di2 technology gives us reliable and lightning-fast shifting for when things get hairy in the paceline. As an added bonus, we no longer have to run around looking for a charging cable since the lever operates off of long-lasting coin batteries.
