I don't have roof rails, just a permanently mounted load carrier with a profile CROSS-section 85 mm wide and about 20 mm high. Alexandra probably meant that the LÄNGSBALKEN (on which the bike stands) is 160 cm long, but this information is of no use to me. It's about the brackets with which the base plate is screwed to the load carrier.

The crossbar is 1.6 m long. The fastenings on the roof rails are universal.
