Goldstone Grips Color:White with an optional 250Wh PowerMoreJackson Goldstone worked directly with our 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. FEATURES: Oversized Bar End: Goldstone Grips have a large outer flange that keeps your hands from slipping off the ends. Jackson chose a ramped shape on the bar ends to give him something to push into
