Dunlop Aero Boost Grommet Technology

AERO BOOST GROMMETS

The wider opening of these grommet holes allow the string to move freely within the grommets. This additional string movement creates more power and a larger sweet spot than other traditional grommets.
A soft material is put between the frame and grommet/string to create a spring like effect. This spring like effect gives the player more power and as well as increased touch when needed.
Parallel drilling is one of the latest crazes to sweep through the top five racquet manufacturers. Parallel drilling allows more of the string to freely move without touching the frame. This additional movement creates a larger sweetspot and more power.
