I needed and I will need this kind of tool to carry 2 or 3 bikes for short trips (summer vacation: 300 kms, weekend hikes for cycotouristes: Max 40kms) .I hate this kind of accessories (roof box, trailer etc ...) but I admit that it has not moved a hair, if the straps are not desserées despite 3 bikes that I hooked this was .the record is clear, the emcombrement out raisonnable.un use small control after qques kilometers and everything is for the best .I recommend purchasing that has a + Hours of Operation as excellent value.
