2015 USATF Outdoor Champion Jared Schuurmans says; The rim weight of the discus is relative to comfort and skill level. Low rim weight discus doesn't necessarily go far and high rim weight discus are not guaranteed to go further. Finding a weight that is comfortable to the athlete and his skill level is the best chance in optimal distance.
Low rim weight discus in theory are designed for beginners and as the weight goes up the logic is the discus will spin faster.  Making it more aerodynamic and carrying the ability to go further. However,  if the athlete does not have the ability to spin the discus well in a higher rim weight, will result in a reduced distance because the discus will wobble and create drag.

Secrets and tips to throwing farther from the Pros

  1. Rim weight is a comfort and skill mechanism that does not increase the distance that you can throw, but rather it increases the ability to maintain the aerodynamics and airfoil longer through the duration of the throw.  Heavier rim weights increase the radius and allow higher-end throwers to apply forces.
  2. Too high of a rim weight may allow the discus to stop spinning throughout the throw and the rim weight works against the thrower diving prematurely. Any discus that stops spinning dies and is subject to dive as the outside rim weight on the edge of the disc to dive.
  3. Head Wind conditions will cause the discus dive on the back side,  moving down a shorter distance rating and a lesser rim weight will increase discus throw stability. 
  4. Side winds dives are again due to rim weight imbalances, move to lower distance rating to cut through the wind for retention and more stability.
  5. Tailwinds move to a lower distance rating.


When top discus throwers consulted, we listened, “Rim weight was not the important factor to long throws, it is Power Retention RimGlide tm.” 
This new design technology keeps the discus balanced over longer duration of throw, resulting in longer throws! Discus Balance.
