Très solide et sadapte très bien sûr mon véhicule. The tighter you push the unit towards the tire, prior to tightening, the more resistance you will have. I hope this vendor does a solid and allows us to exchange for a new pair. I retired another pair because they looked way to big and now this new pair is almost too small. Will take time to get use to removing and installing the bikes. Due to lack of cross-bracing, if you wobble any side to side as you sit, the bench wobbles with you. But otherwise they are very nice. I purchased these in 7. Así que en resumen, la relación costo-calidad de este producto es excelsa, luce muy bien y se adaptará en donde sea que lo usen, sus materiales son de primera linea, bonitos y resistentes, ya que parece durará mucho. Nope.
