Overview
Hit heavy and dictate the match. The Wilson Defyer 100UL V1 is designed for aspiring high-performance players who want powerful, controllable spin in an ultralight frame that’s effortless to maneuver. The magic starts with TORQ Shaft Tech, a sculpted shaft design that delivers leverage, stability and maneuverability to help you rip heavy, penetrating spin that pushes opponents out of position. A Dual Taper Beam and Parallel Drilling expand the sweet spot for confident response under pressure.
Parallel Drilling
Grommet construction provides a consistent, more forgiving string bed response while dramatically increasing the sweet spot.
DirectConnect
Enhances feel and torsional stability through a carbon fiber handle directly connect to the end cap.
SI3D
A flexible hoop enhances ball interaction and playability while a stiffer throat increases power and spin.
Click-and-Go
Bumper and grommet system for easier replacement, durability and superior fit.
Dual Taper Beam
Creates additional power and forgiveness for heavy baseline exchanges through a variable beam height.
Torq Shaft
Specially designed shaft efficiently transfers kinetic energy from the swing into the hoop, putting more action and speed on the ball.
Airfoil Bumper
Integrated airfoil slipstreams smooth airflow around the hoop and minimize resistance for faster swing speeds and effective shot shaping.
Elite Spec Control
Ensures consistency frame to frame with our tightest-ever quality control. Weight +/- 5g, Balance +/- 0.5cm, Swing Weight +/- 5kg-cm^2
