The Infinite Discs Sphinx is a 9-speed understable control driver. With published flight numbers of 9 / 6 / -3 / 1, it is most often described as suited for hyzer-flip drives that stand up and ride flat, long anhyzer lines around an obstacle.

Overview

The Infinite Discs Sphinx is an understable speed-9 driver rated 9/6/-3/1.[3] Infinite pitches it as a crossover mold — “the perfect disc for new players who want a distance driver / control driver crossover that won’t fade too soon while covering as much distance as possible.”[2] Infinite is unusually specific about the tooling, writing that “the bottom mold is similar to the Innova Roadrunner while the top is much like the popular Innova Valkyrie.”[3] That wording is hedged, so the parentage is a resemblance Infinite asserts rather than a confirmed part list. The PDGA measured it at 21.1cm across, 1.6cm tall, with a 1.9cm rim and a 175.1g maximum.[1]

Flight characteristics

Flight numbers describe the published behavior of the disc when thrown at its design speed. Real-world flight varies with plastic, weight, age, and thrower power. The community-averaged numbers above reflect crowd-sourced observations from real throws — typically slightly more understable than the manufacturer's published values, which is the most consistent pattern across nearly every commercial mold.

Infinite markets the Sphinx to two audiences at once. For newer players it is a distance disc that will not fade out early: “with an understable release and manageable speed rating, the Sphinx can fly with accuracy and ease.”[2] For stronger arms Infinite calls it “a wonderful, understable utility disc for hyzer-flips, long anhyzer throws, or power rollers.”[2] Stability varies noticeably between plastics — Infinite’s own run log records that the G-Blend run “came out slightly more overstable than the I-Blend runs.”[3]

Best for:

  • Hyzer-flip drives that stand up and ride flat
  • Long anhyzer lines around an obstacle
  • Power rollers off the tee
  • A first distance disc for a developing arm

Plastics & variants

The Sphinx is available in the following plastic blends from Infinite Discs:[3]

I-Blend, S-Blend, Swirly S-Blend, G-Blend, Metal Flake C-Blend, Metal Flake Glow C-Blend, Halo S-Blend

Plastic blend significantly affects flight character. Premium plastics like Champion, Z, or C-Line generally fly more overstable when fresh and hold their stability over time. Base plastics like DX, Pro, or Active beat in faster and become more understable workhorses with use.

History

The Sphinx was PDGA-approved on 29 March 2018 under certification 18-30, and the PDGA published Infinite’s launch copy two days later.[1][2] Infinite’s run log dates the first production run to April 2018, following a 193-piece prototype run, though that log’s post dates are internally inconsistent and should be read loosely.[3] The Infinite Discs line is molded by Innova, a partnership Infinite’s Todd Durrant put on the record in 2021: “The partnership for our Infinite Discs brand is with Innova. It is planned to stay that way.”[4] He also explained why Infinite mold lineages are normally vague — “the Infinite Discs molds are often variants and reconfigurations of existing Innova molds … Under the terms of our agreement with Innova, we can’t publicize exactly which mold parts are being used for which discs.”[4] Against that background, the Sphinx’s published Roadrunner-and-Valkyrie description is unusually forthcoming.[3] Weights have swung widely between runs: Infinite noted of one that “a high percentage of discs in this run were light weight (140g – 150g) in order to market them as a beginner disc or a child-friendly disc option.”[3] Zoe AnDyke carried two I-Blend Sphinxes in her 2020 bag.[5] No designer has ever been credited.[3][4]
