Ektelon's 2014 ESP O3 White 170 Racquet is much more than just a cosmetic update! By shifting some of the weight towards the head for a new 2 point head-heavy balance, Ektelon was able to increase the power level of this model from the previous 3300 up to 3800 without increasing the overall weight of the racquet. Packed with Ektelon innovation, this stick features a combination of a large sweetspot (O3 ports), long main-strings (DPR - Double Power Ring), plus one of the most open string patterns in the game (ESP - Extreme String Pattern). Both pros and amateurs who loved the previous O3 White racquet will appreciate the powerful updates to this classic Ektelon model.

All racquets come factory strung with a wrist cord installed. Click the Specs tab for more details.

Comments: This racquet has excellent power with no vibration transfer, however it does take some getting use to that you can feel the vibration in the handle. Overall, I would say this is an excellent racquet especially if you are prone to tennis elbow.

Comments: I bought this racquet a few months ago.I tried kennex,eforce x5,head x 3,harrow x 2.I always loked the harrow soverign 170, but the handles come off them.just a nail looking pin that wallows out the hole and the pin comes out.This ektelon reminds me of the harrow.But the regular string pattern gives it much more feel and control.The hex grip gives me a sure way of channging from forehand to backhand.on 1-10 scale of power with the eforce apocalypse being a 10 and this racquet being an 8, it suits my swing speed best.I am 66, b player.Use standard string.I have had it for about 20 games and it already looks like the strings are ready to break.I hope ektelon addresses this problem.
