The new Diablo Edge and Diablo Edge Tour 8.5 Drivers are designed to give golfers a distance advantage every time they tee it up. The 4-piece Fused Titanium design creates the most weight efficient titanium 8.5 Driver Callaway has ever made, generating long, penetrating trajectories. The chemically milled Hyperbolic Face produces Callaway’s highest, most consistent ball speeds over the entire face. The new aerodynamic body shape reduces drag during the downswing up to 8%, creating faster impact speeds. Finally, the Aldila Habanero shaft provides incredible feel and is the perfect complement to maximize the 8.5 Driver’s performance.
