* Please note. Like all hollow forged crank arms, there is a visable line or seam at the end of each crank arm. This is not a defect or manufacturing problem and will not cause the crank to fail. As a result of how the arm is formed and is where the bladder used to create the hollow structure is removed and closed up. Every crank arm that is hollow has a place on them where the molding process has to be closed off after the hollow process is completed, and the end of the arm is the strongest and best place to do it.
