Knight Dranzer
Weight: 3.5g
Remarkably fragile due to the thin yet aggressive design.
Contact points are poorly angled in both directions, causing it to suffer from severe recoil while having relatively limited power in either direction.
Interestingly, due to the unique nature of RC Blade Bases, it is one of the better choices for RC Super Flat Base should it ever be legal, providing more aggression while the RC Base reduces its recoil.
Not competitive as the rules currently stand.
Weight: 14.1g
Middling weight and unremarkable weight distribution.
Outclassed by pretty much every common competitive Weight Disk, particularly Ten Balance. Heavier plated versions can sometimes reach the same weight however, which makes them an equal, if niche and impractical alternative.
Generally though, no competitive use.
Spin Gear: Right Spin Gear
Weight: 1.1g each (Shells) + 1.12g (Metal Weight Gear) (Optional)
Standard SG System Shells.
Incompatible with Neo Cores, and thus certain MagneSystem Blade Bases, though Wyborg's SG (Auto Change Version) SG Core Part can be used to allow use with some.`
Generally Neo Shells are preferred for their greater compatibility, mostly their ability to use Neo Cores. For Right Spin, this is particularly relevant with the Heavy Metal Core.
Generally uses a Metal Weight Gear with all compatible SG Cores. This gear helps reduce wobbling/rattling and adds a small amount of weight. It does not, however, work as a gear in any capacity.
Nonetheless, per BBA Survivor, BBA Attacker, BBA Defenser and BBA Balancer having Regular SGs but no Metal Weight Gear, it is not required for legality.
This allows Right Spin Gear Shells to produce the lightest SG setup in the game when using SG (Auto Change Version) and no metal Weight Gear.
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.
Weight: 0.61g
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.
The plastic part is the second lightest of all Core parts, being just slightly heavier than Wyborg's SG (Auto Change Version) core part.
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.
Weight: 4.7g
SG version of Semi-Flat Base.
Tip is slightly differently angled from Semi-Flat Base, being more shallow. Wears quite quickly.
Semi flat tip is nice, being predictable and not difficult to use, but Metal Change Base has better attack, defense, and survival, while Metal Ball Base once worn has a similar but more effective tip shape due to better precession.
It is generally outperformed as a result of these factors.
In addition, Metal Ball Base with Six Metal Balls has a similarly well-behaved tip but 1g more weight.
Nonetheless, it is a competitive part for Compact Customizations as it does work well and they remain competitive using it - just perhaps slightly less capable than with alternatives.
There is a second mold which tends to be slightly heavier than the original, due to two molding cylinders. Performance is generally identical.
Overall
With a fragile, largely useless AR, generic Weight Disk and generic if useful Blade Base, Knight Dranzer is not a particularly good buy, though the Attack Ring would be more useful should RC Bases be legalised.
