Yonex Ezone Grommet & Bumper Guard

You should replace your grommets if you notice the plastic strips are cracked, flattened, or if the bumper guard has worn down to the frame. Additionally, if your strings are fraying prematurely or you feel the frame is losing its structural integrity, it is time for a fresh set.

No, this specific kit is engineered exclusively for the 7th generation Ezone 100 and 100L models. Grommet patterns and frame shapes change between generations, so using this on an older or newer frame will result in a poor fit.

While it is possible to install them yourself, it requires patience and a bit of finesse to ensure the strips align perfectly with the frame holes. If you are not comfortable handling the frame or lack the proper tools, a professional stringer or pro shop can usually install them quickly for a small fee.

Replacing a worn-out bumper guard with a new one will add a negligible amount of weight back to the head of the racquet, essentially restoring it to the manufacturer's original specifications. You likely won't notice a significant change in swing weight, but the racquet will feel more solid and protected.

Grommets act as a protective buffer between the sharp edges of the racquet frame and your strings. If the grommets are worn, the strings can rub directly against the frame, leading to frequent string breakage and potential damage to the racquet's graphite structure.
