Don't let those classic looking arms fool you, these United Severance Cranks have undergone some major attention to detail.  Running a hollowed out 22mm spindle, keeps the strength up but the weight down, and creating arms with a shape to offer greater bend resistance and strength, means these cranks can with stand an absurd amount of abuse. As a final touch, all cranks are supplied with an installation/removal tool and a small sachet of grease, which make fitting them a breeze.
