Shimano 105 Di2 7170 Disc Brake Shifter

The Shimano 105 Di2 7170 Disc Brake Shifter brings electronic shifting to one of road cycling's most trusted groupset tiers — a combination that delivers derailleur-level precision without the mechanical cable runs. Paired with hydraulic disc braking, the lever gives you consistent, modulated stopping power whether you're descending in the dry or riding into a wet headwind. Sold individually as a left or right unit, it integrates cleanly into a full 105 Di2 build.

The ergonomic lever body is designed to accommodate a natural hand position on both the hoods and in the drops, and the reach can be adjusted to suit different hand sizes. Shifting is handled by button actuation rather than a mechanical pivot — small inputs translate directly to precise electronic signals, with no cable stretch or adjustment drift over time. The result is a cockpit that stays tidy and a system that maintains its responsiveness across long miles.
