E-Force Darkstar 170 Racquet
E-Force Darkstar 170 Racquet
+ Demo Racquet


The E-Force Darkstar 170 Racquet features tons of frame designs unique to E-Force including 22” LongStrings for maximum power, bright orange Power Boosters G2 which stabilize the stringbed even on off-center hits, and a long Powerhouse Shaft.  Vibration dampening is provided by the Zero Richter Tubes X2 which encase each main-string through the handle and eliminate the need for a traditional worm-style dampener that may fall out. With durability in mind, E-Force engineers improved upon the Apocalypse Beta frame design by further refining the characteristics (such as size, shape, stiffness, quality, and placement) of the 50 individual graphite pieces that are molded together to create the Darkstar racquet frames.

*Unstrung weight is part of the name given to this racquet by the manufacturer. String never weighs more than 25 grams, so if there is more than a 25 gram variance between Unstrung Weight and Strung Weight then the manufacturer most likely measured the Unstrung Weight of the raw graphite frame (i.e. without grip, grommets, or paint). In addition, due to the porous nature of graphite material, all manufacturers approve of a +/-10 gram variance during the manufacturing process.

Comments: Tried the E-Force Darkstar out from a friend, he almost didn't get it back. What a great racquet. Power is off the charts. I really like the even balance on the Darkstar. Really couldn't ask for anything more out of a racquet. Touch shots up front are there. Control is there. Drive serves are phenomenal! Really looking forward to playing with this beast.

Comments: Just finished my demo with the 170 dark star. All I can say is wow! Very solid frame with incredible power. The control is good but power is outstanding. They say it's not the racquet that wins the game however after using this one I beg to differ. I ended up purchasing after the demo. Would def recommend to all players.

Comments: Love racquetball have tried every mayor brand in the market. Purchased the Dark Star 170 strung it with Oxygen 17 at 30lbs, the racquet became the most powerful racquet that I ever played with. The control and touch was excellent, has a large sweet spot and felt lighter than 170. Will recommend this racquet to all my friends!!

Comments: Just got this racquet last week before our state doubles and we won the Mixed Open.  Racquet feels great, never had so many aces in doubles before.

Comments: I've now played with this racquet for about a week and what can I say ..... WOW.  First off the power seems rather expansive.  When I think I've reached the end to the on ball energy the racquet can produce ... BAM ...  More ball velocity for the next shot.  If you like putting pace on the ball this is the racquet for you.  Coupled with all this power is a HUGELy forgiving sweet spot that produces nearly limitless shot precision.  I've found that even off sweetspot strike produce predictably directed shooting.  All I can say is if you're looking for a top class racquet this is the one.

Comments: Stunning power with lots of control. No vibration/solid and dampened. My drive serve has been lights out. Light and quick up front even at 170 grams/unstrung. Big improvement from my Apocalypse 160. Choose this stick, trust me.
