Lucky Steely Pro Scooter Brake. This is the first flex brake Lucky has offered. This brake uses 18 gauge spring steel. Adding the Lucky Steely brake to your scooter will ensure that it is dialed! The Lucky Steely brake will work on our older Stinger and Motion decks and our current Crew, Strata and Clover decks. The brake comes with 2 M5 bolts, nuts, and anti vibration pad.
