Overmold discs are a combination of two types of plastics used for one disc, one for the rim and the other for the flight plate. The result is a heavier rim and lighter central core producing straighter, longer, and more accurate results.
The ergonomic overmolded rim is softer and may have a more tacky feel. It’s comfortable providing a better grip and chain grabbing ability.
The central core or flight plate is firm and stiff providing better control and consistent performance.
Two color designs are visually pleasing.
