Further to previous comments, this truck is a little too expensive: the blue sleeves do not seem very resistant to shock and it is also true that the setting wheel is "cheap", while an axis slightly longer and a pin would have guaranteed their outfit. But the supporting structure is metal, and surely enough to 100kg, which suits me. And especially its design is very clever, and is suitable for occasional use and outdoor large tires "balloon" used to walk up and down stairs. Recommended.
