The Head MicroGel Radical Oversize is the latest version of Head's hugely successful Radical series, inspired by Andre Agassi. Head has kept most specifications consistent with the Flexpoint Radical OS, but now with a lighter static weight and the added benefit of MicroGel technology. MicroGel offers aggressive, competitive players ultimate feel, unique touch, and added stability. When combined with carbon composite fibers in the racquet head, MicroGel deforms and compresses upon ball impact, uniformly absorbing and distributing the impact load around the entire frame, creating a rock-solid feel while offering extra stability against twisting. Note This racquet is pre-strung with Head Sonic Pro 16 at Head's recommended tension of 57 lbs.
