Regular SG Core Part
Spin Gear Core: Regular SG Core Part
Note: The correct name for this part is "Gear" however this name is commonly used to avoid confusion with the Metal Weight Gear in standard SGs.
Small core part to fit into the Base and be clipped to by the Base Clips, holding the Beyblade together. Also used as a ripcord gear by Bearing Gyros Beyblades.
Incompatible with certain MagneSystem Blade Bases as the tip shafts are too wide for the hole in its base.
With Neo SG Shells, it creates one of the lightest setups, making for what is theoretically the best SG for most attack types not requiring a Neo core or their own shafts, though the difference is generally theoretical only, due to the minimal weight difference, and often going heavier is better for rotational recoil control.
Useful for completely optimizing a Spiral Change Base zombie (which are the only competitive stamina types that do not require a gimmicked SG), as cores are not useful for recoil control due to its low friction and the lighter weight in the centre slightly improves survival. Technically SG (Auto Change Version) may be superior as it does fit, but the difference is likely to be too small to measure.
