Overview

What is the Shimano GRX ST-RX610 STI Lever Hood Set for?

The Shimano GRX ST-RX610 STI Lever Hoods - Pair is the genuine Shimano replacement hood set for the mechanical GRX 12-speed hydraulic disc brake levers built for drop bar gravel riding. Sold as a left and right pair, these black rubber covers restore the gravel-specific grip contour and factory finish to ST-RX610 levers after a hard season off-pavement. OEM hoods snap right back to spec without the guesswork of generic aftermarket replacements.

Compatible with ST-RX610 mechanical hydraulic disc brake levers in the GRX RX600 series 12-speed lineup. A small amount of rubbing alcohol on the inside of the cover during install helps the rubber slide cleanly over the lever body. Once dried, the fit is locked in and ready for the next gravel race or bikepacking trip. The right call for mechanical GRX riders refreshing a high-mileage cockpit.

Do these fit ST-RX610 mechanical gravel levers?

Yes. The pair fits ST-RX610 mechanical 12-speed hydraulic disc brake levers in the Shimano GRX RX600 series. The gravel-specific hood profile is shaped for the RX610 lever body.

Will these fit the Di2 ST-RX825?

No. ST-RX825 is the Di2 sibling and uses a different hood part (Y0SL98020). Always match the hood number to the exact lever variant.

Are these sold individually or as a pair?

As a pair. The set includes one left and one right hood, each labeled L or R inside.

Any install tips?

Remove the lever from the bar, put a small amount of rubbing alcohol inside the cover so it slides cleanly over the lever body, align the protrusions with the bracket hollows, and let the alcohol dry. The hood locks in tight and is ready to ride.
