This circular barbell is made from 6AL4V ELI F-136 implant grade titanium. It is internally threaded for comfort during insertion and has countersunk spiked ball ends for a precision fit.
If you are unsure which size ball to choose you may want to select the standard ball diameter which is always the largest diameter listed. (Last one on the list.)
When selecting striped as the color you must specify the two colors in the order comments field when checking out. Please see our Industrial Strength Striping FAQ for the complete list of possible striping choices.
