Ultegra ST-6800 shifters came out in 2013 as part of Shimano's first mechanical 11-speed road groupset, and the rubber hood covers on those levers are usually the first thing to go — cracked at the transition points, torn near the shift paddle, or just stretched out and slipping under the tape. This is Shimano's factory replacement pair (part number Y00E98080), so the fit and shape match what came on the levers originally rather than an aftermarket approximation.

Compatibility runs across three generations of Shimano's 11-speed mechanical road lineup. These hoods fit Ultegra ST-6800, 105 ST-5800, and Tiagra ST-4700 and ST-4703 STI levers — same body casting across the tier, same hood shape, same part number. Shimano designates this as an "A" match replacement, meaning the material, appearance, finish, and dimensions are identical to what left the factory on the lever. If you're running any of those shifters and the rubber is starting to crack near the brake pivot or peel back at the bar clamp, this is the direct swap.

One caveat worth flagging: these do not fit Dura-Ace ST-9001 despite the visual similarity. The 9001 hood body is shaped slightly differently, and while some riders have forced ST-6800 hoods onto Dura-Ace levers, the fit isn't clean and the hood tends to shift under the bar tape. If you're on 9001, source the Dura-Ace-specific hood instead.... Read More
