SG Flat
From Beywiki, the Beyblade Encyclopedia - Presented by the World Beyblade Organization
This is often considered the successor of the Flat BB. The flat tip allows for high movement speed, while the low height allows for effective Upper Attack.

Overall
Although it is usable if there is a lack of better options, SG Flat is severely outdated and outclassed by parts such as the lower, faster Storm Grip Base (Dragoon S)and the faster, longer-lasting SG Metal Flat 2 (Gaia Dragoon V). There is no reason to desire this BB outside of collection purposes.
