Rookie LED Flash wheels are a great way to brighten up your rollerskates. The small LEDs inside the urethane light up as you skate creating a beautiful glow when the wheels rotate. There is no need for batteries either thanks to the clever mechanism inside the spacer which activates the LED lights to shine bright as you skate. The 85a durometer hardness is perfect for both indoor and outdoor skating. These LED Flash wheels also come fitted with ABEC-7 bearings so you can easily swap out your standard wheels for these fun flashing 58mm wheels.
