Shimano Dura-Ace Di2 9170 Hydraulic Disc Lever/Caliper, Left Rear
Shifting performance and controlled and modulated braking performance; the Shimano Dura-Ace Di2 9170 Hydraulic Disc Lever and Caliper, Left Rear sits at the top of Shimano's range.
By utilising electronic wires rather than mechanical cables, this lever and calliper set eliminates poor shifting and braking caused by contaminants, corrosion and cable stretching. Tactile and easy shifting is assured with the simple pressing of the levers rather than having to swing the entire lever, which can be difficult in cold and wet conditions.
The hydraulic braking levers are also incredibly tactile and ergonomic providing effortless stopping power, especially when your hands are on the hoods. The hydraulic reservoir tanks provide pad and rotor clearance auto-adjust and the finely tuneable reach adjuster allows you to find your perfect fit.
Please note, the levers are supplied without electrical cables, as these need to be ordered separately to suit your frame size.
