Aluminum or Steel Wheel
The Trail Tamer Wheel Assembly comes with either a steel wheel (shown) or an aluminum wheel. The steel wheel is stronger, a little heavier and less expensive. The aluminum wheel is lighter and more corrosion resistant. If you plan to store it outside (Not Recommended) or use the Wheel Assembly in salt water, the aluminum wheel is the way to go.
