First Clutch Base (Metal Driger Version)
Blade Base: First Clutch Base (Metal Driger Version)
First Clutch activates at start of battle. Slightly less self-destructive than Final Clutch because the Beyblade resists the destabilisation caused by the Engine Gear's activation, instead it breaks flower pattern and sometimes self KOs.
Has decent LAD compared to most Engine Gear BB's, however as it does not actually assist the LAD of Right Customize Gear (Free Shaft Version) + CEW Light Sharp combos and tends to get in the way, it is outclassed by Normal Base (Wolborg 4 Version) and Normal Base (Rock Bison Version)
Triangular protrusions cause minor recoil issues, but not overly terrible
The lightest Clutch-Equipped Engine Gear Blade Base (with First Clutch Base (Zeus Version) being the heaviest), though both Normal Base (Rock Bison Version) and Normal Base (Wolborg 4 Version) are lighter.
Not a useful part.
