Roto Grip is proud to announce its partnership & support of Big Brothers Big Sisters of America. With the assistance of our very own mentoring duo, “The Shafanie Duo”, we will not only be supporting BBBS at various events across the country, but we will also be donating 5% of our sales to domestic distributors to aid in the development and support of children within the program. So, if you are looking to make a difference both ON and OFF the lanes, then the DUO is the right choice for you!
