Fusion Wheel: Grand
Main article: Fusion Wheel - Grand
Grand is thicker than Earth at the thickest point on its interconnected, smooth design. However, it is not as successful defensively, as it is 3.5 grams lighter than the second mold of Earth. On the Grand Fusion Wheel there are six "walls" and with every two walls there is a gap dividing them into three sections. In each section there is a wall with small textured indents; this creates some recoil, which is never a plus for a Defense-oriented Wheel. Because of this, it does have some Smash Attack, but it is mediocre and is completely outclassed by the multitude of other great Attack-based Wheels available, such as Flash, Variares, and Blitz.
Spin Track: WD145
Main article: Spin Track - WD145
Wide Defense 145 (WD145) features three “wings”. The wings are similar to that of ED145, the only difference being that its wings cannot spin freely. The defensive capabilities of this part are outclassed in all areas by other Defensive Tracks, such as C145, GB145, BD145, and 230, as it does not absorb hits as successfully. Furthermore, it is easy for the low attacker’s Wheel to be caught between the Wheel and WD145, causing a lot of recoil and spin reduction in the process.
Performance Tip: RS
Main article: Performance Tip - RS
RS is a sharp tip made of rubber. RS's primary purpose is to counteract Attack customisations: the high friction of the rubber tip, along with the lack of movement due to the sharp tip make it incredibly difficult to move, and KO.
RS has similar problems to other sharp tips, and is easy to destabilise. RS also suffers from the poor stamina of rubber-based bottoms, and their tendency to wear down after extensive use.
RS also has difficulty sometimes outlasting left-spinning customisations. Against right-spin Attack customisations however, despite its poor balance and stamina, it is able to effectively neutralize them.
