O (Orb)
Analysis
A semi-passive bit with low burst resistance. The round surface creates stability, causing the Beyblade to move around casually while conserving stamina. It has a smaller surface area than B, and as such it has the capacity to spin for longer.
Value
As a stamina-oriented bit, O can be used to good effect on many stamina customizations. Wether or not it is superior to B depends on your desire to trade stability for longevity.
