51mm diameter by 34mm width. It’s an unusual combination: a small wheel with a wide profile. The board sits close to the ground and flips quickly, but the contact patch is generous, so landings don't have that feeling of balancing on nothing that narrow wheels give you.
The shape is called V4 Wide for that very reason, and it is the reason to choose this one over a conventional small wheel.
100A is at the top of the hard wheel scale. It barely deforms, so it slides easily and rolls fast on smooth surfaces. On the flip side, you feel everything, and it’s not a wheel for cobblestones.
