Jackson Goldstone worked directly with OneUp's engineering team in Squamish to design his signature grip from the ground up. From sketching up features at the office to riding prototypes to victory on the World Cup circuit, this is a true signature product. Designed, tested and proven by Jackson. The raised palm provides added comfort, improved ergonomics and a bit of cushion on this otherwise slim grip. It works with the end-flange and finger ridges to give you a powerful, locked-in feel.
