Shimano Dura-Ace ST-R9170 Di2 STI Lever Hoods - Pair

When Should You Replace Your Shimano Dura-Ace ST-R9170 Di2 STI Lever Hoods?

The ST-R9170 Di2 lever hoods are the OEM replacement rubber hood covers for the Dura-Ace R9170 Di2 generation STI levers. Hood rubber degrades over time from UV exposure, sweat, and general use, leading to tackiness, cracking, or loss of grip texture that affects both comfort and control at the handlebar. Replacing hoods is one of the most cost-effective ways to restore the feel of well-worn levers without replacing the entire lever assembly. This pair is cut and contoured specifically for the R9170 Di2 lever body, ensuring a proper fit with no bunching, lifting, or gap at the lever blade.

Installation requires no tools and takes a few minutes. Slight warming with a hair dryer or warm water helps the rubber stretch over the lever body without tearing during fitment. The OEM rubber compound provides the same tactile grip and surface texture as the original hoods, maintaining a secure contact point for hands in the drops or on the hoods during long efforts. Sold as a pair covering both left and right levers. Compatible exclusively with the Shimano Dura-Ace ST-R9170 Di2 lever; other R9100 or R9200 generation levers use different hood profiles and are not interchangeable.
