We have now already the third Unitec Xtreme roof bike carriers and so far have had no problems. They are used several times a year and the bikes also come with you on holiday. We are absolutely satisfied. I've experienced no crooked bicycles or änliches. From a small child's bike to the 28 "Treckingrad everything has fit in.
Only should be checked before each ride, whether the bolts / nuts are still tight enough as they become loose from time to time something.
