Overview

What are the Shimano Dura-Ace ST-R9170 Di2 lever hoods for?

These are the OEM replacement rubber lever hoods for the Shimano Dura-Ace ST-R9170 Di2 STI levers, sold as a pair. Lever hoods wear over time with UV exposure, sweat contact, and daily handling. Replacing them restores the tactile grip, comfortable feel, and clean appearance of the levers without replacing the entire lever body. Using OEM Shimano hoods ensures the correct fit and thickness for the ST-R9170 lever shape. A simple, affordable service item for maintaining Dura-Ace Di2 equipped bikes.

Compatible with Shimano Dura-Ace ST-R9170 Di2 STI levers. Sold as a pair. Verify lever model before ordering, because hood profiles vary between Di2 generations.

Are these hoods compatible with any other Shimano Di2 lever?

No. These hoods are specific to the ST-R9170 lever profile. Di2 hood covers are generation-specific and not interchangeable across different Shimano lever families.

How difficult is it to replace lever hoods?

Hood replacement is straightforward with no tools required. The hood peels off and the new one stretches over the lever body. Starting at the tip and working toward the clamp keeps the fit clean.

Will worn hoods affect shifting or braking performance?

Worn hoods do not affect Di2 electronic shifting or hydraulic brake function, but they significantly reduce grip comfort and lever feel. Replacing them restores tactile feedback and cockpit comfort.
