Shimano GRX DI2 Dual Control Lever

No, these specific hoods are designed exclusively for the Shimano GRX ST-RX815 Di2 electronic levers. They will not fit mechanical GRX shifters due to the different internal lever shape and electronic button integration.

It is a straightforward process that requires no special tools. You simply peel the old hoods off from the back of the lever body and slide the new ones on, though using a little isopropyl alcohol can help them slide into place more easily.

These are sold as a complete set, including both the left and right side hoods, so you can refresh your entire cockpit at once.

Yes, the textured rubber compound is specifically engineered for the GRX series to provide extra tackiness and vibration damping. Replacing worn, slick hoods with these fresh ones will noticeably improve your control and confidence on technical terrain.

It depends on your riding frequency and exposure to the elements, but most riders find they need replacing every 12 to 18 months. If the rubber feels sticky, has lost its texture, or is starting to tear, it is time for a refresh.
