The Bombshell Ratchet Pro cranks are 2-pc race cranks CNC machined in the USA from 7075-T6 aluminum for maximum strength and rigidity. Each arm has a large machined recession on the back to safely remove weight and includes a pinned steel pedal insert to prevent stripping. The 24mm hollow spindle is pressed into the drive side arm and features a 4x104mm spider gear that's secured with a new locking system that increases the contact area between the spindle and arm, providing maximum power transfer to the rear wheel.
