Lucky 7 Bolt drive (BMX cranks)

from $60.00

For use with 1/8 CHAINS ONLY

22mm bore with 19mm adapter included(can be increased to 24mm upon request)

Subtle bolt slot for a very clean look

Custom shaped teeth for strength and longevity

7 double spoke design to look awesome!

NOTE FOR RAW COLOR: Raw sprockets are not polished or coated. They are cleaned and deburred off the machines. This is perfect for doing custom colors. In our experience these parts fair just fine “in the wild” without a coating, but no coating does make them more susceptible to scratches and oxidation.
