Description of the Racquet
Every year E-Force’s comes out with one of the most powerful racquetball racquet series on the planet and this year they decided to tweak it up another notch with their new Invasion line. These are once again available in 4 different weights and 2 shapes. The Quadraforms are the 160 and the 175 and the Teardrops are the 170 and 190. They took the popular High Octane Booster technology from the Heatseeker 2.0 and added more of them for more power and an even more solid stringbed. The High Octane boosters are now red so everyone will know you’re playing with the latest and greatest E-Force racquet wherever you’re standing on the court.
Everyone that has pre-ordered E-Force racquets before knows that supply is always limited in the first couple batches. The first batch is due to arrive around Early November. Racquetworld will have more of these to ship than any other dealer in the world so please order early to guarantee one when they arrive. We will keep you updated if the in stock date or availability changes. Thanks as always for your continued support!
They have 2 Quadraform racquets which are the 160 & 175 (Control w/power) weights and the teardrop racquets (Total Power) come in the 170 & 190 weights.
The longer shaft creates more whip and power creating a more explosive racquetball. It also creates a more solid feel with less vibration, more stability and greater control.
If you're unsure about your model or weight...try our DEMO Program.
These are available in and 3 5/8 and larger 3 15/16 grip sizes.
A racquet cover IS NOT provided by the manufacturer with this racquet. You have the option to add a cover for $10 if you would like.
RacquetWorld's General Notes
I would recommend changing the grip to a Python (Our favorite), or Head TackiMac 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 Prince Premier string upgrade is recommended because factory string is less playable/durable then the Prince Premier string we suggest. At the time of purchase, the Prince Premier restring upgrade is $21.95. It's normally $36 if you mailed the racquet to us later so you save $14 if you choose the upgrade right away.
If you choose a vibration dampener go with the Ektelon Silencer (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 $2.95 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.

New for 2012 - 2013 Expanded Hi-Octane-Boosters
Every year E-Force produces the most powerful racquets on the market and this year will be no exception. They’ve stuck with the same head shapes/weights of their previous year’s Heatseeker Series but expanded their Hi-Octane Boosters from 7 strings to 12 strings on the E-Force Invasion Series of Racquets for more control and power.
What are these Hi-Octane-Boosters going to do for your game?
- They’ll create a more solid stringbed!
- They’ll increase your overall power!
- They’ll give you more power on off center hits!
- They’ll increase shot accuracy and ball control!

POWERHOUSE BREAKTHROUGH - In the past, all racquets had standard shaft lengths with whip and power. The introduction of 22" LongString Technology – available only from E-Force – changed racquetball withincreased power through the use of longer mainstrings in free space. Competitors responded by eliminating the racquet shaft and shortening the handle to allow slightly longer mainstrings, though far shorter than E-Force's. Now another breakthrough – E-Force combines the power of shafts with the power of 22" LongStrings in free space, for maximum power. Only E-Force has it.

Other E-Force Technologies Used
 |
BY-PASS Stringing System - Power and livelier ball response. Mainstrings skip every two holes. The ball does not directly strike two adjacent mainstrings at once. |
 |
Zero Richter Tubes - String vibration is reduced. Mainstrings are enclosed in 100” of vibration-damping tubes hidden in handle. |
 |
Launch Pad Technology - Maximizes power. Eliminates unnecessary deflection-limiting cross-strings in racquet throat. Increases stringbed deflection. |
 |
Recoil Power Edge - Larger stiffer cylinders in hitting area reduces twist /distortion. More stringbed deflection and power. |
 |
Patented Extreme Longstring Technology - All mains and crosses are the longest possible – extend to outside edges of the frame and handle. |
 |
Fiber Alignment (FAT) Zones - More strength and power in racquet head. Pushes out and aligns fibers in high-stress curved areas of frame. |
 |
Total Carbon Head -Adds stiffness, durability and power. Paint and non-structural materials replaced with additional carbon graphite. |
 |
Tri - Carbon Frame - Increased stiffness / more power. Optimum blend of three light, stiff, carbon graphites |
 |
Patented Dual Cyclinder Construction - Ultra-thin, two-tube with bridge construction – longer strings, more power. Reduced frame twist and distortion. |
Exclusive RacquetWorld Racquet Ratings
Ratings and comparisons for all racquets can be found in Racquetworld's Technology/Ratings Section
Racquetworld's Durability Rating: 98.00
Racquetworld's Power Rating: Age 24- 98.00 Age 35 98.50 Age 45+ 97.00
Racquetworld's Control Rating #1 (Front Court): 95.00
Control 1 (Front Court) represents how the racquet handles upfront in the court. We’re basically looking at how certain components stacked together 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’s also good to know if you’re 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): 94.50
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- 96.70 Age 35 96.95 Age 45+ 96.20
