Although the length of kick may end up being a little shorter, the changes make the Telstar 18 more balanced, says Alam. On other balls, Alam and his team have found that there is a difference in how the ball flies based on where it’s kicked in relation to the seams. His tests have found that the Telstar 18 ball doesn’t have as much variation. The total length of seam of the Telstar 18 is 14.1 feet, 3.28 feet more than on the Brazuca. With the longer seam, and more symmetric panels, no matter how the ball is turned there is the same amount of seam exposed. “The other two balls were not like that, they were significantly different,” he says.
Only size 5, and size 4 are available for this. Although this should not be a major problem as this is for recreational play and practicing purpose, so kids are ok to play with this as well. In fact, the ball that will be given away to the developing countries will be used by the kids mostly. If you are buying this for an adult go for size 5, and if you are buying for kids or youth players then better go for size 4.
The Telstar 18, the design for the 2018 World Cup in Russia, is as close to a perfect sphere as you can get. It has subtle pimples and six thermally bonded panels designed to avoid knuckling, which is the characteristic bobbing and weaving movement when a ball is kicked without spin. All 32 teams have been able to play with it since November in preparation for the tournament, which runs from June 14 to July 15. But despite its similarities to the old ball, players have grumbled about the Telstar 18. Compared to the last few World Cup balls, the Telstar 18 is very similar to the ball used for the 2014 World Cup in Brazil. It won’t fly quite as far down the pitch, and will wobble in the air a little differently, but aerodynamic testing suggests it will be more stable in the air overall.
So it is now clear to you that you won’t have to worry about the air retention capability, durability. Now, how good is the playability? Well, in terms of rebounding, this ball performs almost like a standard ball but obviously not exactly like standard balls. Having said that, we must say the rebound is enough for recreational play and practicing purpose. You will also find this ball a bit heavier than standard balls during the shots. That is why we don’t suggest you use this option for tournament play.
Select's attention to detail can be found in the ball's handy work and composition. It comes in nine different colors, including bright orange and bright yellow, which are perfect for training in semi-darkness. The 1.5mm PU cover is hand-stitched and textured for the brighter colors, adding durability. The design also aides turf play by zeroing in on control and resistance.
This year, the ball shouldn’t have that kind of impact on which team wins the World Cup. In wind tunnel tests, Goff found that Telstar 18 has a very similar aerodynamic profile to the 2014 Brazuca ball, which flew without the wobbles of the Jabulani. The Jabulani was the first ball to have six seams and despite having a roughened surface, it was too smooth, says Goff. When the Brazuca was released, it had 68 percent more seams than the Jabulani to help change the airflow around the ball. The Telstar 18 is even more improved. Instead of transitioning to laminar flow in the middle of free kicks, Goff found that the Telstar 18 goes through its drag crisis at a lower speed of 38 miles an hour.
