What Our Customers Say About Our Strings:

Perfectly balanced

I always liked the quality of Tier One Sports strings but I think this is their best offering so far! I used to play national junior tournaments and now compete at high level adult tournaments. Control…check, durability….check, tension stability…check, playability….check!

Excellent string, very unique

"Great string! As a former D-I collegiate player and now having a highly ranked juniors son, we both are playing competitively with T1-Firewire. Definitely worth giving this string a shot. We did... and now it is the string in all of our rackets."

Hoi  //  T1-Firewire


Finally had a chance to string up my Head Speed MP with a 16g T1 Firewire. WOW. Insane ball bite. Not sure if this is even legal. Although the string felt pretty firm I still was able to generate enough pop. Durability and tension stability was great as well. Will be my go-to string in the future!

Steve  //  T1-Firewire

Advanced players string.

"Fantastic string for the price with great bite. A very nice balance of control, power, and durability for advanced players. If you are not an advanced player look elsewhere."

Amazon Customer  //  Black Knight

I tested Triumph side by side with Wilson NXT Tour because I was told that it plays similar to NXT. There is always a degree of doubt about the quality of a "no name" string.
Stringing was easy like any multifilament string. Hitting the first few balls, the string had a very smooth, soft response. I was able to control the depth of my strokes nicely. Drop shots and volleys felt great. Very good feel. But the string did not lack in power either. I was able to hit my spots at the serve and had a few aces. Although the string lacked somewhat in spin (especially in comparison to the new generation polys), I was able to generate enough for my kick serve and ground strokes. Durability: The string started to fray at around hour 5 and broke at hour 6.
I would highly recommend this string for anybody who like to play with an arm friendly multifilament string (like Biphase, Xcel, etc.) but does not want to pay $17 for it

Super soft co-poly

"This is a soft co-poly suitable for a wide range of players. Good spin, control, tension maintenance, and comfort. Want a soft poly, look no further."

Amazon Customer  //  Ghost Wire

Tier One Ghost Wire-Top Notch

"I absolutely love the string. This purchase included my 2nd and 3rd package. I believe that I will be using this string full time. Shipping was excellent. I'm a very satisfied customer with Amazon and Tier One Sports. Thank you"
