The Ultra 100UL V5 is a stunning combination of ultra-lightweight, arm-friendly comfort and power-inducing performance. It marks the next iteration of the game-changing Ultra series.. This frame optimizes manoeuvrability for quick exchanges at the net while dialling up the power with Crush Zone, a grommet system that expands the sweet spot and increases dwell time.. Design innovations start with SI3D, a technology that optimizes frame bending and provides an explosive mix of power, spin and control for intermediate to advanced players. It utilizes patented FORTYFIVE° technology to boost stability for more consistent strokes and greater shot confidence, while dual-tapered beam construction maximizes power without sacrificing forgiveness.. With eco-friendly bumper and grommet materials plus a mesmerizing "electric indigo" finish, this racket is as captivating as it is commanding.. Parallel Drilling. Grommet construction provides a consistent, more forgiving string bed response while dramatically increasing the sweet spot.. FORTYFIVE°. Patent-protected frame layup produces more connected-to-the-ball feel while better complementing the more modern, vertical swing path. Material increases both flexibility and stability without compromise through the swing.. Agiplast. Plant-based bumper, grommet and end cap components reduce overall environmental footprint.. Crush Zone. Innovative grommet system compresses at impact to provide a larger hotspot and increased ball dwell time on the strings, creating better feel and more potential energy that drives explosive power.. SI3D. Optimizes three-dimensional frame bending for targeted power, spin and control.. Click-and-Go. Bumper and grommet system that enhances durability and application through a superior fit.. Dual Taper Beam. Generates power from its height and mobility from the aerodynamic shape.. Specifications:. Head (sq cm): 645. Head (sq in): 100. Length (cm): 68.58. Length (in): 27.
