What does a disc with a "bead" mean?

[Jakeginter]

Also whats all this talk about 11x KC Rocs or 4X Valks? what does 11x or 4x stand for?

[Rooster]

11x and 4x are the times that that player has won the world championships.

the kc and jk plastics change often but are usually blends of pro/champ and pro/other plastics.
and for discs with beads, theres literarly a bead of plastic around the bottom of the rim usually adding stability to the disc.

[Jakeginter]

Ok, Thanks alot. So a Roc has a bead then, correct?

[Blake_T]

yes. as does a cobra, classic roc, gremlin/sniper, rhyno, wasp, banger, kc aviar, sentinel, spider, etc.

there are also less defined beads available on certain drivers such as the cyclone, cyclone 2, x-clone, and x2.

there are also discs with a very abrupt slope at the bottom of the rim which acts somewhat as a "bead" as well. discs like a predator and old mold beast have these.
