Attack Ring - Circle Upper[]

Main article: Attack Ring - Circle Upper

Circle Upper is one of the most useful ARs available. This usefulness is due to the unique shape of its Metal Frame; it is an almost perfect circle shape that completely surrounds the outside of the AR, with two large, deep slopes on either side that are used for Upper Attack. Although it has some Smash Attack ability and Force Smash in left spin, these traits are negligible when compared to the effectiveness of its Upper Attack.

Because of the round shape of Circle Upper, many hits will not be incredibly effective against it. There are very few points of contact for another AR to latch onto during a hit, generally causing the Beyblade attacking Circle Upper to take the majority of the damage.

Circle Upper is the second widest HMS AR available (The widest being Samurai Changer MS's Circle Upper) Because of this, it has one of the widest attack range of all HMS ARs. While not as much of an advantage in Tornado Balance Type S, in wider stadiums where making early contact is crucial, the extra range can mean the difference between winning or losing.

A point of note is the weight distribution on Circle Upper; because there is no metal near the center, only along the outside rim, all of the weight is focused there. This will generally lead to an AR with poor balance, and placing it on a tall RC will cause wobbling. However, there are two ways to negate this disadvantage:

  • The most popular combos with Circle Upper generally use very low RCs, e.g. Dragoon MS's Grip Flat Core, so the poor balance is generally not an issue.
  • There are combos you can build where this poor balance can be used as an advantage, which is discussed on this page.

In contrast to the Metal Frame, the ABS Caul mostly serves to be a cradle for the Bit Protector. Most of the contact with the opposing Beyblade will be with the Metal Frame, another one of Circle Upper's great advantages.

Circle Upper has very few disadvantages and many advantages, and this is why it is one of the most-used ARs of all time.

Mould Differences[]

There was a change made to the mould of Circle Upper's Metal Frame. The change was first employed at the release of HMS Random Booster ACT 3, and was also released byHasbro. The second mold has a Metal Frame that is reinforced along the entire Upper Attack slope. The result is that it is significantly thicker and weighs more. This does alter the balance so that it is even more prone to wobbling. The previous mould is lighter and has better Survival capability. These moulds are referred to as "first mould" and "second mould", respectively. You can select one or the other depending on your strategy.

Use in Upper Attack Customization[]

Death Gargoyle MS's Circle Upper and Samurai Changer MS's Circle Upper dominated as the top choice ARs for Attack-types. This style of combo can be used effectively to defeat Survival types such as Wolborg MS in many stadiums.

  • AR: Circle Upper (Death Gargoyle MS)
  • WD: Circle Wide
  • RC: Grip Flat Core (Ultimate Version) (Dragoon MS UV)

Use in Wobbling Customization[]

While wobbling is a strategy that is often difficult to implement effectively, this is one of the few ARs that makes it a viable strategy. You can combine it with a Survival-type core to beat other Survival-types. The Smash Attack gained from Wobbling, along with Circle Upper's innate Upper Attack and the Survival capabilities of its round shape make this a good strategy to attempt.

  • AR: Circle Upper (Death Gargoyle MS)*
  • WD: Circle Wide
  • RC: Bearing Core (Wolborg MS)

*Select the first mould Circle Upper for more Survival ability, or the second mould for more Attack ability.

Shared Metal Frame[]

The second mould of Circle Upper's Metal Frame is the same Metal Frame used in Samurai Changer MS.

Weight Disk - Circle Heavy[]

Circle Heavy is a Weight Disk that, as its name suggests, features a circular design and a heavy weight. Due to its high Outward Weight Distribution (OWD), Circle Heavy excels in both Attack and Defense combinations. Circle Heavy can be used when the much rarer CWD Defense Ring and CWD God Ring Weight Disks are unavailable.
