BowlerX.com is an Authorized Roto Grip Bowling Retailer - Nobody sells Roto Grip Bowling products for less. FREE expedited shipping on every item. Roto Grip has been a leading industry innovator since it was founded in 1955. Then, Roto Grip bowling balls were unique in that they were pre-weighted. The most famous of these balls was the Blue Polyester Roto Grip, which was very comparable to the Columbia Yellow Dot of the late 1970s and early 1980s. In 1997, Storm Products purchased the brand name and produced its first Roto Grip ball in 1998. Better known as “The Ball Banned from the PBA Tour,” the SD-73 put Roto Grip bowling back on the map. Roto Grip - King of them all!
