Jones Mind Expander. The Mind Expander is an alternative all-mountain board that was born of surfy turns. Float playfully atop the fluffy stuff on a Jones Surf Rocker profile, and devour tree runs on a 3D Contour Base 3.0 with a tight sidecut. Jones Traction Tech also allows you to lay down carves with confidence on hardpack.The Mind Expander features a 100% FSC Bamboo Surf core for better edge response and rounded recycled ABS sidewalls for improved durability. New for 2021, the Mind Expander has a Sintered 8000 base and Carve Pack inserts that offer the option of a more centered stance for ripping hard pack.
