About Bolt Racquets
The fundamental principles of racquet design have not changed since the days of the wooden racquet. In order to absorb ball impact energy and reduce ball rebound speed, composite racquets are designed to flex like wood. While ball rebound speed is controlled, and a degree of comfort can be achieved, a flexible frame is less accurate and less powerful than a stronger more stable frame. Simply put, the balance of control and power in a racquet has always been a compromise. Until now.
BOLT has revolutionized the racquet by shifting control of ball rebound speed away from the frame and into a patented design called a ZipStrip™. A ZipStrip is a spring-like string support that absorbs ball impact energy. Instead of the frame flexing to control rebound speed, the Zipstrip flexes. It enables every BOLT racquet frame to be solid and stable - designed for optimum precision, accuracy, and control—at any level of power.
Perfected through years of research, ZipStrips are the core engineering innovation of a BOLT racquet. ZipStrips cooperate with the strings at ball impact to improve every aspect of racquet performance:
A BOLT is a true control frame at all levels of power
All BOLT racquets are stiff and stable - even the pro level racquets which typically are designed to flex. The ZipStrip flexes to control ball rebound speed while the frame stays firm and powerful. This makes it possible to have optimum precision and control, with maximum power.
Consistently solid contact
The entire string-bed of a BOLT racquet is responsive. There’s no sweet “spot”; the whole string-bed is dynamic and alive.
Impact shock and vibration are practically eliminated
ZipStrips act as shock absorbers, responding to ball impact before forces are transmitted to the frame, not just dampening vibration after the fact like a conventional racquet.
Superior torsional stability on off-center contact
A ZipStrip increases the flexibility of the string near the frame edge to minimize twisting. While conventional racquets may resist torque, ZipStrips actually reduce the magnitude of the torque exerted on the frame.
Vastly increased dwell time over a conventional racquet
With a BOLT, most of the strings ride on a ZipStrip, not the frame. The ZipStrip acts like a suspension system that responds dynamically to ball impact. The result is a distinctive pocketing effect in which the string bed cradles the ball and then launches it from the strings.
Reduced string breakage
ZipStrips reduce stress in the string near the frame edge, where a powerful off-center ball impact can often break a perfectly good string.
