Why Rim Weight Matters

Rim weight percentage strongly influences how a discus feels and performs:

• Lower rim weight (up to ~70%) is easier to control and ideal for technique development.

• Moderate rim weight (~70–80%) offers a balance between spin and stability for emerging competitors.

• High rim weight (~80%+) maximizes rotational energy and is best suited for advanced throwers with refined technique

✅ FAQs

Q: Are the discuses legal for NFHS, NCAA, and World Athletics competitions?

A: Yes! All of our discuses meet the specifications required for NFHS, NCAA, and World Athletics sanctioned events.

Q: What is discus rim weight?

A: A discus is made up of three main parts: the rim, side plates, and a center core. Rim weight refers to how much of the total weight is concentrated in the outer rim—usually expressed as a percentage (e.g., 70%, 80%, 85%). The higher the rim weight, the more potential the discus has for long flight distances—but it also becomes more challenging to control.

Q: What is a low rim weight discus?

A: A low rim weight discus (up to 70%) is easier to control and spins more slowly, making it ideal for beginners or developing throwers. The Gill S6 and S7, and Thrower X 70% rim weight discus are great options for beginners.

Q: What is a moderate rim weight discus?

A: A moderate rim weight discus (typically 70–79%) offers a balance of speed and stability. It’s a great choice for intermediate or progressing athletes.The Gill S7, Nordic Valkyria, and Fibersport Storm are great options for emerging elite throwers just starting to reach higher levels of performance.

Q: What is a high rim weight discus?

A: A high rim weight discus (80% and above) spins faster and can fly farther—when thrown with proper technique. These are best suited for advanced or elite throwers with strong form and speed. The Polanik Gold Carbon, Fibersport Pro Series, and the Nishi Super HM are great options for elite throwers, according to Throws Pro owner, Coach Scott Cappos
