Notable Tech, Materials & Construction

Genuine Shimano OEM Fit

These bracket covers are shaped to match the original Shimano Ultegra ST-R8170 lever body. The correct factory fit helps the hoods sit neatly over the lever without bunching, twisting or lifting around the edges.

Ultegra ST-R8170 Ergonomics

The ST-R8170 lever platform is designed for modern road riding, with a compact hydraulic hood shape that supports comfortable hand positions during climbing, sprinting, descending and endurance riding.

Grippy Rubber Hood Surface

Fresh rubber hoods restore hand traction and control, especially when old hoods have become shiny, slippery, sticky or stretched from sweat, sun exposure and repeated use.

Clean Factory Finish

The black Shimano finish gives the cockpit a clean, original look that suits modern road bikes, premium carbon builds and professional Shimano Di2 setups.

Practical Cockpit Refresh

Replacing worn hoods is a small service job that can make a bike feel significantly newer. It improves comfort, hygiene, grip and overall cockpit presentation without replacing the full shifter or brake lever.

Ideal With New Bar Tape

New bracket covers pair perfectly with fresh handlebar tape. Together, they restore the main rider contact points and improve the feel of the bike straight away.
