AD1

The AD1 is the first PDGA-approved mold from Circus Discs, a small maker the PDGA lists in South Africa.

The PDGA approved it on January 26, 2026 under certification 26-8, recording a 21.1 cm diameter, 1.3 cm rim, 1.6 cm height and 1.3 cm rim depth. The submitted sample is a hand-labelled 3D-printed prototype marked only "AD1 / Circus Discs / 162g", with no disc class or flight stamp, so the midrange classification carried here is inferred from geometry rather than published by the maker.

Circus Discs has no discoverable website or retailer, and no flight numbers or named plastic exist for the mold.
