The Bombshell Ratchet cranks are 2-pc race cranks CNC machined in the USA from aluminum. Each arm has a large machined recession on the back to safely remove weight without negatively affecting it's strength. 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.
