The Decathlon Inesis Tour 900 ball has made great inroads into the premium ball segment in recent years. With the current version dating back to 2021, it was time to update its performance for 2024.
The objectives for this new version are clearly defined:
Did you know that the maximum distance a golf ball can travel when driving is limited by the Royal & Ancient (R&A)? Our old-generation Tour 900 ball was already close to the limit. But it was still possible to improve performance by 1 or 2% to get a little closer to the limit.
To do this, we modified the composition of the core to create a "faster" material, i.e. one that generates more ball speed on driving and on the irons, while releasing more energy on impact.
We've also modified the coat (the middle layer). Made from Surlyn, a benchmark material in the golf ball industry, it is now 30% thicker. It's not harder than before, but because it's thicker, it's stiffer, which increases ball speed.
We've gone for around 1 mph (1.6km/h) more ball speed, which equates to around 2 yards (1.83 metres) more distance. That's enough to overdrive your buddies, isn't it? :)
The compression of the old-generation Tour 900 ball was high, at around 100 points. The aim was to bring it down to 95 points. The problem is that there's an almost linear relationship between ball hardness and ball speed. The harder the ball, the faster it is, and vice versa.
As far as we were concerned, it made no sense to increase the speed of the Tour 900 and make it softer at the same time.
However, our engineers succeeded in doing just that, working on both simultaneously. As we have seen, speed has been boosted thanks to a thicker mantle and a faster core. This core is also significantly softer, which in turn has reduced the overall compression of the new Tour 900, for the benefit of a softer feel and greater pleasure with every ball strike.
Historically, the Inesis Tour 900 has always been a ball with a lot of spin. This is a good thing when wedging, as it allows you to stop balls very quickly, but it can become a handicap in terms of total distance if you can't keep the spin down when driving. Spin plays a major role in distance, which explains why, between two players, the one with the longest drive isn't always the one with the fastest ball speed.
We therefore wanted to reduce the spin of the new Decathlon Inesis Tour 900 to gain distance on driving and irons, by generating a more penetrating trajectory. By increasing the thickness of the mantle and opting for a softer core, we were able to achieve the right spin rate on every type of shot.
The result: the same grip on the greens, but more distance elsewhere.
Our designers have worked on the aesthetics of the new Tour 900. It has been given a new "ice blue" color, a white that veers very slightly towards blue. Of course, it's still a white ball, but if you compare it to the old version, the difference is perceptible and reinforces its premium appearance.
The markings have also evolved. The number is now black, which is the norm for balls with a compression of around 90/95 (it's red for balls with a compression of over 100).
The packaging has been redesigned, so you can easily identify which version of Tour 900 you're buying.
Last but not least, we've kept the alignment line you're so fond of, which goes perfectly with our range of putters.
High-performance golf balls are required to excel on the driver, irons and wedges. Schematically, each of these 3 shots corresponds to a layer of the ball:
The new Tour 900 ball was tested by MyGolfSpy in their major bi-annual test.
The result: the new Tour 900 is up there with the best, especially the Titleist ProV1.
