Bombshell Spinnergy Mini Cranks
The Bombshell BMX Spinnergy Mini cranks are 2-pc race cranks CNC machined in the USA from 6061 aluminum with large recessions on the back of each arm to save weight, 4-bolt 104mm spider gear with machined cutouts, and a 24mm hollow 7075 aluminum spindle that is pressed into the drive side arm to increase the overall strength and stiffness while reducing weight.
