The Delmar Indy is a type of Indy grab where the skater tweaks their body so that the board curls behind them. It is basically a slightly tweaked tuck knee air. Both of these tricks are a type of frontside air where the skater grabs towards the back of their board tucking their knees together. Not many skaters know that this trick is called the Delmar Indy. Most people just call it a tuck knee.
