Tecnifibre TFight 315 Isoflex Tennis Racket (Unstrung)

Battle for every point with the Tecnifibre T-Fight 315 Isoflex (Unstrung) in White/Black, as endorsed by the powerhouse that is Daniil Medvedev.
Refined once more with Isoflex technology, the T-Fight 315 boasts a more forgiving, more consistent string bed that makes for reliable, satisfying performance on every type of shot.

Isoflex refers to the frame’s variable stiffness – harder composites near the shorter strings make the strings flex more on ball contact, while softer composites near the longer strings make those strings flex less. You get a more balanced overall feel and a significantly larger sweetspot to accommodate off-centre hits.

The RS Section five-sided frame geometry from previous editions remains, helping to reduce twisting and giving you greater power and control, while also improving the pocketing sensation for improved comfort.

The heaviest racket in the range, the 315g edition features a smaller 98 sq in head and an open 16x19 string pattern for extra spin, making it the ideal choice for experienced players who like to play powerful shots that dip just inside the line.

Daniil Medvedev

Daniil Medvedev, born in Moscow in 1996, is a Russian professional tennis player celebrated for his unique playing style and mental resilience. Rising rapidly in the ATP rankings since turning pro in 2014, he established himself as a formidable player on the global stage. Known for his impressive baseline game, exceptional defensive skills, and ability to adapt to opponents' strategies, Medvedev won his first Grand Slam at the 2021 US Open. His deep and flat groundstrokes, combined with his unconventional but effective serving technique, have made him a difficult opponent for even the most experienced players on the tour.


Since their formation in 1979, French brand Tecnifibre have lived up to their name, remaining at the forefront of tennis tech and producing some of the most innovative products on the market.

In fact, you might be using one of their inventions without realising it: back in 1983, they came up with the idea of utilising polyurethane to make synthetic strings more comfortable to play with, a concept that’s been a mainstay of the industry ever since.

It’s a good example of the company ethos of putting the player first, especially those who are just starting out. That’s always been the thinking of founder Thierry Maissant, who young players can thank for the specifically sized and weighted junior frames that are now commonplace. Frustrated by his own experiences as a junior, having had to play with rackets that were too long and too heavy, he began his business by commissioning some shorter, lighter frames, selling them under the moniker of Major Sports in the late 70s. Major Sports then secured a partnership with the French Tennis Federation to produce rackets for their new mini tennis programme, and the Tecnifibre brand was born.

To this day, they place special focus on young players, catering for all ages with their extensive range of junior frames and supporting up-and-comers with initiatives such as their Young Guns Contest, which helped Daniil Medvedev launch his career when he took home the cash prize in 2016.

Medvedev still uses a Tecnifibre racket, of course – the control-focused T-Fight – while another prodigious talent, Iga Swiatek, wields the Tempo, a range that’s tailor-made for female players. There’s also the all-rounder’s TF40, the arm-friendly yet powerful TF-X1, and the accessible T-FIT collection, which brings top-notch performance to casual players. A true tennis brand with players at its core, you can’t go wrong with Tecnifibre.

Control Racket

Control rackets usually have closed string patterns – essentially, more strings per area – to increase ball contact and give you more control over your shots. They tend to have thinner beams to allow more flex and often utilise material technologies to make you feel more connected to the ball.

Choosing the Right Grip Size for your Tennis Racket

One often overlooked, but crucial, aspect when selecting a tennis racket is the grip size. The grip size is the measurement around the handle's circumference, and choosing the right one can significantly impact your comfort, control, and potential to prevent injury. This article will guide you through the process of selecting the right tennis racket grip size.

Importance of Choosing the Right Grip Size

A correctly sized tennis grip ensures you have optimal control over your racket and helps prevent injuries. Too small a grip may cause your hand to shift during play, reducing accuracy and increasing the risk of developing tennis elbow due to overuse of the forearm muscles. Conversely, a grip that's too large can make the racket hard to turn and manipulate, and it could also lead to hand, wrist, or shoulder injuries due to overgripping.

Measuring Your Grip Size

There are two common methods to measure your grip size:

  1. The Ruler Method: Open your dominant hand and extend your fingers. Align a ruler with the bottom lateral crease of your palm, measuring to the tip of your ring finger. The measurement in inches correlates with your grip size.

  2. The Finder Test: Hold the racket with a standard Eastern forehand grip, where the base knuckle of your index finger is on bevel #3. You should be able to fit the index finger of your other hand in the space between your ring finger and the palm that's gripping the racket. If there's not enough room for your finger, the grip is too small. If there's too much space, the grip is too large.

Grip Sizes: U.S. vs. European

In the U.S., grip sizes range from 4 inches to 4 ¾ inches, increasing in increments of 1/8 inch. European grip sizes use a different naming system, L0 to L5, each correlating to their U.S. counterparts as follows:

European Grip Size US Grip Size
L0 or G0 4 Inches
L1 or G1 4 1/8 inches
L2 or G2 4 1/4 inches
L3 or G3 4 3/8 inches
L4 or G4 4 1/2 inches
L5 or G5 4 5/8 inches

Choosing the Right Grip Size

When choosing the right grip size, consider the following points:

  • Go for the smaller size if you're in between: It's easier to increase the size of a grip than decrease it. You can always add an overgrip (which usually adds about 1/16 inch) to a smaller handle to increase its size, but shaving down a larger handle is not recommended as it can compromise the racket's structural integrity.

  • Consider your style of play: Players who rely on spin might prefer a smaller grip size, which allows for more wrist action. In contrast, players seeking control may benefit from a larger grip size.

  • Test it out: If possible, try before you buy. Visit a local sports store, hold the racket, and mimic your swing to see how it feels. Remember that comfort is key - if it doesn't feel right, it probably isn't.
