50-50 Grind
The 50-50 GRIND is a foundational grind: you ollie onto a rail or ledge so BOTH trucks land on the edge, then slide (grind) along it on the trucks before ollieing off the end and rolling away. It's the entry point to street grinding and demands a solid ollie, precise placement, balance while sliding, and commitment.
