GFX drop through longboard from Ehlers Longboards.
You have to love this one!
The longboard drop through is a symmetrical board.
The nice thing is that you do not have to turn the board around when you go back, that has a cut out at the front and end, allowing the base of the trucks to be mounted through the deck. When doing this, the board will be lower to the ground allowing a greater stability at higher speeds.
