Upgrade or replace your Shimano ST-R9100 Dura-Ace STI Brake Lever Hoods with these genuine Shimano Bracket Covers. Specifically designed for the ST-R9100 model, these high-quality black hoods ensure a snug fit, optimal grip, and a refreshed feel for your handlebars.
I'm not really sure how the standard varies say from Ultegra to Dura-ace but due to persperation and grime the rubber hoods can become quite sticky and deteriorate over time. I wonder if gel would be that much different. Overall a great product for the price.
