Shimano Dura-Ace Di2 ST-R9170 Hydraulic Shifter

Shimano Dura-Ace Di2 ST-R9170 Hydraulic Shifter

Dura-Ace Di2 hydraulic levers have never felt better than with the ST-R9170 shifters. Improved tactile feedback reduces vagueness when shifting in chaotic situations or with thick winter gloves on, and the braking mechanism has been engineered to provide the perfect balance of power and manipulation when racing in the peloton.
