Getting hung up in Roll-in
Mechanism / Why It Happens
Hanging up happens due to how your body axis tilts and the structure of the skateboard
As a basic premise, your weight needs to be leaning forward during a roll-in. If your body leans forward while standing on flat ground, your front foot supports your weight, so you will not lose balance. However, in a roll-in, the moment the front wheels come off the coping, your body loses that support and falls forward together with the board. As a result, only the back wheels get stuck on the coping.
