This includes their proprietary compounds which have been extensively researched and tested by top athletes around the world to ensure that they provide the highest level of comfort and longevity possible. They are also the innovators of the Lock-On Grip system, which innovated the way in which grips are installed and secured to the handlebars and still remains the worldwide standard for grips.
