Duncan Gyroscopes feature quality die-cast metal flywheels, specially designed for perfect balance and maximum spin times as well as a durable plastic frame with special dimples for balancing the gyro on different objects, or balancing multiple gyroscopes on top of each other.

The Gyro XT includes an interactive CD-ROM that contains not only Gyro-specific tricks, but also gives detailed instructions on performing various stunts and feats with Duncan’s spinning top line. The CD-ROM will feature selected members of the Duncan Crew WorldWide demonstration team, as well as music from notable independent record label No Idea Records, based in Gainesville, Florida.
