Shimano Ultegra ST-R8070 Di2 STI Lever Hoods
What Are the Shimano Ultegra ST-R8070 Di2 STI Lever Hoods and When Should You Replace Them?
The ST-R8070 Di2 lever hoods are the replacement rubber covers for Shimano's 11-speed Ultegra Di2 hydraulic disc STI levers, the ST-R8070 series used on flat-mount disc brake road builds with electronic shifting. Hoods serve a critical functional role beyond aesthetics: the Shimano textured rubber compound provides the primary grip surface for the hands-on-hoods riding position, protects the Di2 electronic components inside the lever body from moisture and debris, and cushions vibration at the handlebar contact point. Rubber degrades over time through exposure to UV light, sweat, sunscreen, and general wear, resulting in hardening, surface tackiness, cracking, or tearing. Replacement restores grip quality, seals the lever body, and keeps the cockpit looking clean without requiring any disassembly of the brake caliper, hydraulic system, or Di2 wiring.
The ST-R8070 hoods are specific to the R8070 lever body profile and are not interchangeable with the mechanical ST-R8000 Ultegra lever hoods, which use a different shape, or with Di2 levers from the R8150 generation. Installation is tool-free: the worn hood peels back from the lever body and the replacement stretches over it, aided by a small amount of isopropyl alcohol to ease fitment. For riders on Shimano Ultegra ST-R8070 Di2 hydraulic disc builds who need to refresh worn hoods, this is the correct OEM replacement set.
