900 IRONS / Chapter I

From brief to design.

Beginner, intermediate, advanced. 100, 500, 900. At Decathlon, we have three levels for all sports. For golf, we have decided to organise them as follows:

Level above 30: beginner
Level between 15 and 30: intermediate
Level below 15: advanced

After having redesigned the beginner (100) and intermediate (500) clubs, it was time to tackle the advanced club (900).

WHO ARE YOU? ADVANCED PLAYER?

OK, a player who plays at under 15. But besides that, it's also a milestone achieved in your approach to the game. Above all, an advanced player loves to envisage their shot and pull it off. “Flag at 150 metres, green on a slight plateau, large bunker on the right of the green. OK, that would be a fade 7-iron, tight shot.” When the ball flies exactly as the player mentally visualised, it's a sheer delight. At that moment, they have this feeling of being in total control of their game and too bad if the shot is not an easy one. Even better. There is one putt left to envisage and pull off.

The key word, it's control. For us, an advanced golfer is a player who seeks control.

THE HOLY GRAIL IS THE BLADE.

What type of club offers the most control?

We first need to agree on the concept of control. This begins with perfectly regular distances.

When you take the same shot ten times, the distance is the same each time.

It's also immediate feedback through your hands. You know exactly where you have struck the ball.

It's the ability to precisely execute the trajectories that you are looking for: draw, fade, flop, punch.

The type of club that offers the most control is the forged blade. A sleek and exclusive club, beautiful in its simplicity. Playing with blades also means being part of this category of players who know how to play with blades.

Yes, because they are also difficult clubs to play with. This is the drawback. An off-centre ball and you'll feel it directly in your hands. If the ball lacks energy from the club when it takes off, you lose 10 metres. You pay for any poor contact with the ball. For smaller clubs, for an advanced player, anything up to an 8-iron is OK. After that is where it gets complicated. As if golf wasn't already complicated. We just want to make golf easier, even for advanced players.

So how did we do it?

THE “HOLLOW BODY” CLUB REVOLUTION

“Hollow body” actually refers to the head of the club. In fact, it is really interesting because a cavity inside the club allows the player to benefit from volume and a more precise distribution of mass compared to a solid clubhead. In view of this; we'll position the centre of gravity according to the characteristics we want to give the head: forgiveness, power, take-off angle for the balls, spin, etc.

Other types of clubs do this as well (cavity back). But the advantage of a “hollow body” head is that we can design it like a blade. This is what interests us.

“The combo: the best of both worlds”

From the 8-iron to the pitching wedge, the 900 irons are forged blades. Starting from the 7-iron, we've opted for a “hollow body” head. And on the 3-iron and 4-iron, where the aim is a powerful and accurate first stroke or a distant green, we have designed “utilities” to give you more distance and forgiveness. A set comprising blades, hollow-body irons and utilities. This is what we call a “COMBO” and is the best combination that we can offer you for your score. The best of both worlds.

DESIGN MY ADVANCED SET

The design brief is simple. Design athletic and elegant clubs, with the codes that advanced players expect. Minimal offset, a narrow sole, a small head. The difficulties of the project essentially lay in trying to apply these same codes to the different types of clubs: blades, hollow body, utilities.
