PDGA Approved Kastaplast Berg X

The Kastaplast Berg X is Coming

Update: Check out our Kastaplast Berg vs. Berg X comparison, here!

Continue reading below for an overview of the Berg X and it’s specifications.

TL;DR: Kastaplast is making a stable version of the Berg that is stiffer and will most likely have a thicker rim and higher parting line (causing it to be more stable.)

Yup, you read the title right. The Kastaplast Berg X was just approved by the PDGA today, May 22nd, 2023. While flight numbers haven’t been released, we can only assume that the Berg X will be following suit with the Discraft Zone OS, Venom, Innova Juggernaut and other extra-overstable discs released this year.

Berg X vs. Berg Flexibility

Comparing the two discs, we can’t really see a huge difference between the two aside from a centimeter of height and the Kastaplast Berg X coming in stiffer. Here’s a wonderful discussion on the PDGA’s Disc Flexibility so you can learn more about exactly what this spec means. 

A brief example of disc flexibility would be looking at the Elevation Discs Koi, a disc made to flex and flop by the use of silicone rubbers compared to the two above discs. The Koi comes in at a .56kg flexibility, while the new Berg X hits a 6.82kg and the prior Berg model is 4.31kg. Essentially, the Berg will flex less in the hand, feeling quite a bit denser. 

The question still remains, does that mean anything for the stability or flight of the new Berg X? Not necessarily. The PDGA requires the manufacturer to send in whatever is their most rigid plastic they plan to produce the disc in and Kastaplast may have sent in a very rigid model of the disc compared to the original Berg. That being said, Rim Shape could have a lot to do with flexibility.

Berg X Rim Shape

So will the difference between the Kastaplast Berg X and original Berg come from rim shape? For this type of speculation, let’s take a look at the difference between the Discraft Zone and Zone OS. The Discraft Zone OS is considerably heftier in the hand than the original Zone and according to the PDGA’s website, the Zone OS clocks in a 12.05kg flex compared to the Zone’s rating of 10.55kg. One can only image the Berg X will have a bit denser rim shape and a higher parting line (here’s a great article on how the parting line effects disc stability from Green Splatter.)

But for now, all we can do is speculate about how the Kastaplast Berg X will fly until it arrives on websites for what will most likely be the most sought after disc drop of 2023. Let us know what you think of the new Berg X below!
