Release Date
              Introducing the new Aspire Spare Ball, a critical piece to any arsenal! Featuring the Tyro weight block and a polyester cover, the Aspire spare ball is designed to go as straight as possible. You can have confidence when shooting at your spares that your ball will go exactly where you want it to go.
The Tyro core is designed to neutralize the imbalance created after drilling finger and thumb holes. This provides Aspire bowling balls with a stable trajectory that is ideal for spare shooting.
This polyester cover is designed to go straight. This cover is engineered to see very little friction. You can be confident that this ball will not hook when shooting at spares.
