The disc is the most important part of ultimate frisbee.
It is what makes the game what it is.
Thus, buying a premium ultimate disc can make all the difference in playing the sport.
This guide has it all covered.
From teaching you about things to consider when buying your first frisbee disc to reviewing the best ultimate firsbee discs in 2020.

Ultimate Frisbee Disc Buying Guide
Material, design, construction, and weight are the primary parameters you need to consider while selecting the Ultimate Frisbee disc.
Design and construction are guided by the scientific principles of aerodynamics, gyroscopic stability, velocity and the angle of flight.
The ultimate Frisbee disc should have a circular shape with a National Ultimate Association recommended minimum diameter of 10.25”.
It should have a cavity spot at the bottom for enhancing the aerodynamic lift and reducing the reverse-drag force when it is in motion.
The recommended standard rim-edge curvature is 0.15”.
The flight rings above the edge should provide a firm grip to hold the disc with your thumb placed on the edge and the index finger along its circumference.
It should provide support for the other three fingers to spread out evenly and get a firm hold.
Material and Construction
The preferred material for the ultimate Frisbee disc is the hard plastic that is molded for the National Ultimate Association approved quality standards.
The weight should be between 170gms and 180gms. The top surface of the disc should be relatively flat compared to the rim. The material could be polypropylene, PC, or ABS.
It is the outer-third of the disc whose symmetry provides the aerodynamic force and stability. Its angular curve starts at the flight plate and extends up to the rim.
It should be less than 45-degrees for balancing the flight direction and providing spin to the disc.
The spinning (rotation) of the disc keeps it moving forward without collapsing to the ground during the flight.
The speed of rotation depends on the shape of the Morrison slope and the rim edge curvature.
By ensuring the values are within the standards, you can get the best ultimate Frisbee disc for your gaming.
Hold the disc with the thumb above the Morrison slope and the other four fingers on the rear-side. Throw the Frisbee flat and observe its motion.
The flight path should be straight with no deviation from its intended path.
The disc should rotate continuously on its path until it hits the ground. Then you can be sure of its gyroscopic stability.
Aerodynamic lift is the upward movement of the disc at an angle relevant to the ground. An increase in this angle can result in an increase in distance covered.
An optimum rim-edge curvature (standard as specified) can increase the speed and keep the reverse drag (formed by the wind blowing in the opposite direction of flight, object weight, and the force of inertia) at the minimum possible level.
The hard plastic material should be of engineering grade that can pierce through the air-density at an average speed of 14-16 m/s. It is a parameter which you’ll need to check practically.
The angle of attack depends on the construction of the Frisbee’s Headrick lines.
They should be equidistant from each other and their height should not be above the script-band which separates them from the flight-plate.
Such construction helps in increasing the angle of attack to the optimum value while throwing. The momentum leads to higher speed and force, making it difficult for the opponents to catch the disc.
Hammer throw becomes simple and effective making it difficult for the opponents to block the flight.
The surface underneath the rim rear-end should have a firm grip for you to hold. It plays a critical role when you need quick passes between your teammates.
It helps in smooth flow of the disc to earn extra points during the game.
The trajectory-velocity of the disc can vary, depending on the attack angle and the force used for a throw.
Reverse drag will be more when you play the game near the seashore on the beaches or in open spaces.
The location of the cavity spot plays an important role in optimizing the velocity while nullifying the effect of drag.
Standard discs will have a point near to the navel at the center of the flight-plate circle.
The overall construction and design of the ultimate Frisbee disc should provide you control over its handling, holding, throwing, and catching.
You can check the control level while using it for backhand and forehand throws.
It gives you the ability to control the speed, direction and distance coverage along with the angle of flight and landing.
It will also allow you the freedom to increase or decrease the rotational (spinning) speed, depending on the angle of attack and the distance between you and the opponent player.
Best Ultimate Frisbee Discs In 2020
1. Discraft 175 gram Ultra Star Sport Disc
The twin layers of script-band with a thick layer of Headrick lines give a high attack angle to the Discraft Ultra Star disc.
It is made of high-grade engineering plastic for longer durability and resistance to the elements while playing outdoors, especially on the beach.
The plastic is tested for skin-friendly composition with no irritants and allergens.
National Ultimate Association approved the design for the Morrison slope helps in varying the aerodynamic lift according to your specific requirements.
For example, you may wish to play the high-backhand which needs added power to the throw on the go. It is made possible through the construction sync between the strip band, flight rings, and the flight plate.
The position of the cavity spot at the navel makes it possible to experiment with the elevated passes and throws at the maximum speed.
You can also vary the spin RPM (rotations per minute) with a gentle variation in the throwing angle and elevation. It pushes the disc to the maximum height and land at the desired destination at high speeds.
Swing is the best throw when you wish to achieve maximum speed at intermediate heights.
The rim structure of Discraft disc allows you to control the flight and increase the speed with its unique core construction.
Firm plastic construction with soft exterior finishing
The granular surface texture on the flight rings for better grip
Designed for optimum speed at various angular movements
White color may have reduced visibility while playing outdoors during the evenings
6. Da Vinci Team Ultimate 175 Gram Flying Sport Disc
The design of Da Vinci disc is flat from the flight rings to the core of the cavity spot at the center. The angular deviation inclines-down evenly through the Morrison slope to the rim and Shelton line.
The professional shape and construction density ensure the most optimum speed, rotation, angular momentum, and elevation angle.
The rim has a smooth finishing with perfectly polished edges.
