Ibex

The Ibex is Vibram's straight, versatile rubber midrange, rated 5/4/-1/1. Vibram described a stable, controllable approach disc whose signature was a smooth, seemingly unending fade for controlled lines, accessible to newer throwers while remaining dependable for stronger releases. Its unusually tall 2.4 cm profile and 1.3 cm rim distinguish its hand feel from many conventional midranges.

The PDGA approved Ibex on February 24, 2011 under certification 11-06. Vibram's own material pages described X-Link Medium as a high-grip, scuff-resistant rubber compound with strong shape memory. Vibram closed its disc golf division in February 2018, so those pages and the discs themselves survive only through archives and occasional limited restocks. Vibram named several X-Link families of its own, including Firm, Soft, Float, Glow and Granite; Granite Medium is a visual treatment of classic X-Link rather than a separate feel family.
