New Era of Racquet Performance

Strong-Stable Frame


Dynamically Responsive String-bed


Power, Control and Comfort


BOLT has built a new type of racquet based on an engineering paradigm which enables power, control and comfort to be optimized together on the same frame.

No more compromising between power and control. Every BOLT racquet is powerful while at the same time providing amazing control and comfort.

High-Impact Tennis

BOLT has built a racquet from the ground up for modern high-impact tennis.

The modern game is primarily about power. Players want more power and more power means stiffer frames. In order to generate enough spin to control the power, strings have to be stiffer too. As racquets and strings get stiffer, impact forces to players' arms increase significantly.


To make things worse, stiffer frames are relatively brittle and far less capable of absorbing energy than wood, for example. Today's racquet is far less a buffer between the ball and the body but more of a conductor, shooting vibration and impact forces of all frequencies directly into players' arms.

It's clear that the trend toward power will continue, and impact forces are only going to rise. At some point something has to give, literally. It's not an accident that arm and shoulder injuries have increased sharply, particularly at the tour level.


Tennis at advanced levels has changed significantly through more than two decades of carbon composite racquets and yet racquets themselves haven't really changed at all.

BOLT understands that racquets must evolve too. We have been inspired to develop a fresh approach with a new design model specifically suited for the modern game. The result of our research and development is the ZIPSTRIP. The future of racquets is here today!

Tech Driven Growth

​​It's safe to say that the design and performance of tennis equipment and racquets in particular, have been the target of focus as both an art and a science since the earliest days of the game. A brief glance through etchings, drawings, photos and patents makes clear the depth of thought and creativity that have gone into the field over more than 100 years.  Brief History of Racquet Design - BOLT

At BOLT we celebrate this rich history in our pursuit of advanced innovation in racquet science. We know that tennis players often develop special "relationships" with their racquets. It's a player's direct connection to the ball and the game itself, and the most experienced players will invariably have a long list of preferred specifications.

It's this unique relationship of player and racquet that has made technological breakthroughs in racquet design particularly impactful over the history of the game. A single significant shift in technological capacity has often fueled major leaps in interest and participation, as well as changes in the way the game is played.

We hope to provide a spark of innovation for tennis. We're committed to making the game easier to play, more comfortable, and more powerful than ever before.

One of our chief goals is to help improve the tennis experience through innovation and objective analysis.

New Design Model

The fundamental principles of racquet design haven't changed since the days of wooden racquets. In order to absorb ball impact energy and reduce ball rebound speed, high-tech composite racquets are designed to flex like wood. While a flexible frame can control ball rebound speed and provide degrees of comfort, it's inherently less accurate and less powerful than a stronger, stiffer and more stable frame. Simply put, conventional racquet design is locked into a broken paradigm which results in a compromise between power, control and comfort in every racquet, without any quality being optimized.

BOLT has advanced to a new design paradigm that doesn't result in a compromise between power, control and comfort . BOLT has revolutionized the racquet by shifting control and comfort 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 to control ball rebound speed. Instead of the frame flexing to control ball rebound speed, the Zipstrip flexes. It enables every BOLT racquet frame to be solid, stable and powerful while at the same time providing amazing control and comfort.

In applying the engineering model of suspension to racquets, and utilizing the latest in high-tech materials and manufacturing techniques, BOLT has moved past the conventional paradigm and raised the bar for racquet performance to an extraordinary new level. The time of bone-rattling off-center shots, arm and shoulder torturing ball impacts, loss of ball control at high-speeds, and embedded compromise is over.

The BOLT is a dynamically responsive instrument, not just a stick with strings.
