String Description

YTEX Quadro Twist Tennis String Video Review By 5k Tennis

The Quadro Twist is our "Baby" and flagship string from YTEX.

If you are looking for a very' SOFT co-poly and a SPIN Monster...then this string is for you! This is the absolute best' string on the market you can get besides natural gut! RSI (Racquet Stringers Industry) rated the Quadro #1 in spin and #2 overall out of 157 strings they playtested. 

Quadro Twist has outstanding tension hold and is also highly recommended for the main or cross in a hybrid combination. If you've never played with a poly string then the Quadro is a great introduction for you to the poly world. 

Note: The black color on this string does play a SOFTER' than the white color so be sure to get the right color according to what you are looking for in a string. The Quadro is a little livelier so this one you can string a bit tighter than normal. 

Color: Black.
Length: 40ft/12m and 660ft/200m
Gauge: 16L (1.26mm)
Construction: Carbon + Co-Polyester.
Advantage: Power combined with great spin and feel.

What YTEX Strings Players are saying

Tired of choosing between spin and a sore elbow? 
Most poly strings give you bite or comfort – never both.

Quadro Twist’s four-edge twist grips the ball and absorbs impact, so you hit heavier topspin without the post-match ice pack.

YTEX Quadro Twist Review By 5K Tenis

Poster

Engineered for Extreme Spin

Quadro Twist’s square-twist shape grips the ball, sending shots down fast instead of drifting long. That’s why the USRSA lab ranked it #1 for spin out of 157 strings.

"Strung at 45 pounds, she felt the racquets came alive with great spin and comfort. She couldn't be happier! She'll be another long term customer."

Gentle on your arm

Softer than most polys. Players with elbow or wrist issues report pain-free hits. String it 2–4 lb tighter for steady control.

"My college players love these strings. They are arm friendly for my players that have arm problems and they love the feel and spin it gives them."

Works in Any Setup

Full bed or hybrid. Quadro Twist stays lively and holds tension. Black color plays a touch softer; white is slightly firmer.

Not Your Typical Poly

Most poly strings make you pick spin or comfort. Quadro Twist gives you both, plus better value every time you restring. Here’s how it stacks up against a typical polyester option.

YTEX Quadro Twist's FAQs

What tension should I use?

Start 2–4 lbs tighter than your usual poly for maximum control.

Is it safe for tennis-elbow sufferers?

Yes – Quadro Twist’s low stiffness and vibration damping make it one of the most arm-friendly polys (see doctor-approved playtests).

Durability vs RPM Blast?

Similar life for heavy hitters (6-10 hrs), longer playability for most club players due to better tension hold.

Black vs White colour?

Black plays ~5 % softer & livelier; white is slightly firmer for flatter hitters.

Does it work in hybrids?

Absolutely – many pros pair natural gut in mains with Quadro Twist crosses for spin + comfort.

Comfortable and spin friendly

I tested the Quadro Twist (black 1.26) and Hexagon X (red 1.25) in two Wilson Blade Pro V8 18x20 racquets strung at 47lbs. Both sets were on the racquets for about 10 hours of play time before conducting the test. The criteria was:
1. Comfort: Simply how it feels when the ball contacts the string bed (very subjective)
2. Control: Based on hitting smaller targets (20 balls in drill)
3. Spin-friendly: Based on the height of the ball bounce (20 balls in drill)
4. Power: Trying to hit lower, penetrating shots (20 balls in drill)

All testing was with a ball machine to eliminate variability from a hitting partner.

1. Comfort: The Quadro Twist was more comfortable.
2. Control: Quadro Twist = 18 and Hexagon X = 15
3. Spin-friendly: Quadro Twist = 17 and Hexagon X = 15
4. Power: Quadro Twist = 8 and Hexagon X = 11

The least accurate was related to Power as I was personally struggling with this aspect of my game...Not the fault of the strings.

Based on this, and the fact that both strings were playing well at the 10 hour mark, I'll be ditching the Head Velocity MLT and using the Quadro Twist. But, I also enjoyed the Hexagon X!

Found my staple string

Tried ytex on a whim when I heard about square x sharp. Thought it would be a novelty and I'd be back to searching around to find something that would fit my needs and protect my elbow. Immediately noticed a difference. Play tested several others but their flagship ended up checking all the boxes for me. I string an ezone 100 with a full bed of quadro twist black at 48lbs. Spin generation and power with full cuts from the baseline have helped my rally depth tremendously. First serves still pop, but my confidence with kick and slider has gone through the roof. Anyone looking to get into the brand should start here and see what it does for them!

LOVED THE STRINGS

I gifted 2 sets of YTEX Quadro Twist black to a 4.5 student who needed new strings in her Head Radical MP racquets. Strung at 45 pounds, she felt the racquets came alive with great spin and comfort. She couldn't be happier! She'll be another long term customer.

Everything you need in a string!!

I used to string my rackets hybrid style until I came in contact with the Ytex Quadra Twist strings. I no longer need a hybrid pattern due to these strings, giving me the power control, spin and elbow safety that I require. I play with a Head Radical and string the mains at 42 and the crosses at 40.

Switched from Luxilon ALU Rough

I made the change to give my injured wrist a break from stiff polyester strings, and I got a little more power and spin too. So far so good. I installed this string on the mains and X One on the crosses. I think it’s a great combination.
