If you want to customize your setup over time, you'll be stoked to hear that this scooter is compatible with numerous wheel sizes and all of Tilt's Stage III collection. Whether you're just starting or upgrading from your current setup, the Theorem Complete is your best option to progress both your setup and your riding.
