The racket comes unstrung from the factory. The signature performance of the Clash 100 Pro has been improved in terms of comfort, power and playability, while maintaining the game-changing flex and stability that are the hallmarks of the Clash series. The Clash 100 Pro V3 utilizes patented SI3D technology that changes the frame's flex capabilities to provide a more targeted approach to power through obstacles. Increased comfort and improved forgiving make everyone feel like they're in the sweet spot, which translates into better consistency even with off-center contact. The plant-based Agiplast grommets, grommets and cap feature durable components to reduce environmental impact. Parallel Drilling - The grommets provide a consistent, more forgiving string response while significantly increasing the sweet spot.FORTYFIVE° - Proprietary frame layout provides enhanced ball feel.
