Description
Fitness Mania – Jim Bradley Polycarbon Speedball Swivel Please Note: An original Jim Bradley design, this polycarbon swivel represented a significant breakthrough in swivel design when it first came onto the market place. Jim Bradley swivels are a dramatic improvement form the old, heavy, “S” swivels. Combined with the shorter strap of Jim Bradley speedballs, use of this swivel leads to a drastically reduced length of the arc of the speedball when struck, leading to a truer, quicker hit and a more intense and beneficial workout.
