The Ultrasonic Frame is the first 3 wheel frame designed especially for hard shell freeskates, perfect for all kinds of urban skating, long distance, fitness skating,
marathon skating and freeskate. These frames are exceedingly strong with multiple reinforcements and designed with great care to make them as low and short as possible.
The rear two wheels are kept close together to allow the frame to stay low to the ground but also adds improved maneuverability as turns are exectuted using the heel.
We love the Ultrasonic frame and believe it to be the finest 3 wheel frame available for 125mm urban skating.
