A real bargain for you: This one is strong and sturdy. Manganese raceway and Dust proof ring are not something you'll see everyday. This one will last very long at minimum maintenance effort. The wheel is soft and protected by 2 covers.
The 2-stage ball bearing is made of heat-treated steel to increase friction and wear resistance. The heat treated swivel neck ensures a secure hold of the bearing balls in harsh situations. Has Z shape dual brake pedal - very light and easy to use.
