Shimano 105 Di2 7170 Shifter/Hydraulic Lever with 7170 Disc Brake

The Shimano 105 Di2 7170 Shifter/Hydraulic Lever with 7170 Disc Brake brings electronic shifting and hydraulic braking together in a single, clean lever body — no cables, no clutter. Sold individually as either a left or right unit, each lever gives you the ergonomic control and precise motor-driven shifting that defines the Di2 platform, paired with hydraulic stopping power designed to handle the demands of road riding in all conditions.

The brake caliper is designed with increased pad clearance — 10 percent more than previous generations — to reduce the likelihood of rotor rub during long rides or when the wheel flexes under load. A one-way bleeding system means brake maintenance is straightforward, without the back-and-forth of a traditional bleed process. The lever reach is adjustable, so you can dial in the fit for your hand size before you ever turn a pedal. Note: a rotor is not included.
