Maximum Stability. Maximum Forgiveness. The Cobra OPTM MAX-K Driver achieves our highest MOI ever. Engineered through advanced supercomputing, its optimised weight placement and refined shaping create Cobra's most forgiving driver head. Expect straighter shots, reduced side spin, and exceptional forgiveness. ON TARGET. ON REPEAT. ON OPTM. OPTM drivers utilise strategic shaping and weight placement to minimise Products of Inertia (POI), the measure of a club's resistance to twisting across multiple axes at once. Resulting in reduced side spin, tighter dispersion, increased accuracy, and more fairways hit. Shaping That Blends Speed, Accuracy And Forgiveness A refined head shape perfectly balances aerodynamics, speed and forgiveness to reduce side-spin and maximise club speed on off-center strikes. Maximize Stability Through MOI-Tuned Weighting The OPTM MAX-K driver features a fixed back weight (11g) that positions the CG low and back to maximize MOI and club stability Maintain Speed On Off-Center Strikes A forged face insert with H.O.T. Face technology delivers improved face flex for more robust distance and ball speeds on every strike.
