The 5-0 Grind- The 5-0 grind is like the 50-50 grind except you only grind on one truck. To do it all you got to do is have your fingers in ollie position. When you reach the obstacle, ollie and lean your hand back a little so you can land on your back truck. You will have to ollie higher than you would for a 50-50. Once your on grind and come off. This trick requires a lot of hand eye cordination, so you will need to practice alot.
The Nollie-The nollie is the exact oppisite of the ollie. If your regular position, this means that you put your pointer finger on the nose and your middle finger in a comfortable spot(usally the middle). From here its just like a regular ollie. Bend your knuckles when landing and roll away.
The NoseGrind-The nosegrind is the exact oppisite of the 5-0 grind. Here you will grind with only the front truck. This trick also requires alot of hand eye cordination, so you might have to practise a little before saying you can. Have your fingers in ollie position, but maybe have your pointer finger further up than you would.
