RacquetWorld General Notes
RacquetWorld recommends changing the grip to a Python (Our favorite), which will be $11.00 installed, for the added traction to prevent slippage. The Racquetworld Grommet Tape upgrade ($1) can save you $$ in the long run as sometimes strings break from the grommet being worn down. For those who don't know what the grommet is, it's the plastic piece at the top of the racquet that the strings go through.When you hit the wall and floor this gets worn down.
The Python Atlas string upgrade is recommended because factory string is less playable/durable than the Python Atlas string we suggest. At the time of purchase, the Python Atlas restring upgrade is $24.95. It's normally $40 if you mailed the racquet to us later so you save $15 if you choose the upgrade right away. Another string we highly recommend is the Python Atlas Deluxe restring upgrade ($27.95), and its a little softer than the original Atlas for those players that prefer a softer string with incredible playability/durability.
If you choose a vibration dampener go with the Python Vibration Dampner (Our favorite), Head Megasorb, Gamma Worm or the BBB (Big Bad Band).
The wristlacer black is the default wrist tether that comes on your racquet at no charge.If you want to change colors, a small fee of $3.95 will be added for switching.
A question we get everyday is "What is Grommet Tape?"It's a piece of tape that goes over the head (bumper) of your racquet. Sometimes you need a restring because of a broken bumper.For an extra buck to add this, it could save you $25-40!!
We get follow up calls/emails everyday thanking us for the upgrades as they really help bring out the performance of the racquet.
Racquet Covers - Choose one for $8-$12 (RacquetWorld Cover is Only $8.00)
A full racquet cover is NOT provided by the manufacturer with this racquet. You have the option of adding a full cover for $8-12 if you would like. If you want the best cover on the market buy the Racquetworld Cover. It is oversized, has a full outside pocket, a handle strap and a large shoulder strap as well as a ventilated pocket to let your grip breathe and best of all its $2-$4 less than the others because we want to help you by supporting our company! The charge will only be $8.00 when added to the cart for this choice instead of $10.00-$12.00 like the other covers.

Exclusive RacquetWorld Racquet Ratings
Ratings and comparisons for all racquets can be found in RacquetWolrd Exclusive Racquet Ratings
Racquetworld's Durability Rating:
Racquetworld's Power Rating: Age 24- Age 35 Age 45+
Racquetworld's Control Rating #1 (Front Court):
Control 1 (Front Court) represents how the racquet handles upfront in the court. We are basically looking at how certain components stacked together to produce good (or bad) racquet maneuverability. To figure this out we look at the weight, balance point, and shape of the frame. We throw all this info into Pat's brain along with a couple hours of hit testing and out pops the rating. This value is useful especially for doubles players who find themselves covering the upfront court a lot. It is also good to know if you are a good server and find yourself quickly putting away returns off your serve without leaving front middle court.
Racquetworld's Control Rating #2 (Back Court):
Control 2 (Back Court) represents the traditional control rating when taking a full shot from mid to back court. Our goal with control is to redirect the Force of the ball. We again focus on weight, balance point, shape, string pattern and tension, frame stiffness and on court experience.
Racquetworld's Overall Rating: Age 24- Age 35 Age 45+

Gearbox GB3K Series Racquet Technologies
3K Technology - New for 2021
Using only the best materials and processes to engineer this collection, the 3K Woven Carbon Fiber material helps reduce unwanted vibration feedback, giving the racquet a smooth solid feel. In addition, it provides the frame with more strength and durability.
Enhanced Frame Response
Your new GB3K racquet will give you a more crisp and lively feel, is the most powerful Gearbox racquet to date. With improved Durability from the 3K Woven Carbon Fibre & Extended C3 Power Grooves
EXTENDED C3 Power Grooves Technology
EXTENDED C3 POWER GROOVE,Gearbox engineers extended the internal C3 Power Groove to now run the entire inside length the racquet. The C3 Power Groove creates three concave shapes in the structure of the racquet.
Maximized Sweet Spot
C3 Power Groove enlarges the size of the overall string bed, giving the Beltran racquet an even larger “sweet spot” for more Power and Control.
Parallel ridges run the length of the Solid Graphite Head improving in-plane frame stiffness and reducing deformation. More energy is returned to the ball for superior power and accuracy. Impact energy is channeled downward and away to protect weakened areas caused by drilled string holes in the frame structure. Displacement Channels strengthen racquet structure and improve durability.
Power String Bed
Unique Power String Bed is designed to accommodate the use of thinner gauge string which is ideal for improved Power, Control and overall performance. Wide string space around the frame’s edge lessens friction and allows more stretch for increased Power. Dense String Pattern design provides additional string support at Sweet Sport to improve ball contact for exceptional control.
Vibration Control System
Exclusive adjustable rubber damper system for customized feel. Contract to eliminate vibration or stretch to increase string vibration feel.
