The Orso energy ring is translucent brown with two apparent 'bear claws' on either side that helps with weight distribution. It acts simmilar to the bull clear wheel, but lighter. The recolor comes with the claws coloured gold. It also comes in a transparent light blue colour.
Rock has six large protusions with small, small gaps betweeneach one. It also overhangs the Track much like original Leone Fusion Wheel, although to a small extent.
Rock is currently the third heaviest Hybrid Wheel System Wheel to date. however, as a Defense Type, it is unable to match the qualities of Metal Wheels such as Earth and Virgo, because the shape of Rock produces a significant amount of recoil upon contact with another Wheel. As a result, Rock is an outclassed Defense Wheel.
D125 features 1 circular shield-like circle that goes out of the track body. The ring is meant to protect from low attackers but is no use due to no attackers being able to reach under the 125 spin track. It does, however, add to the overall weight and therfore has uses. It is viable for use in Stamina and Attack customizations.
