Borrowed some decent trail bikes this year from someone who was away over the summer, but they returned now, so handed back, but we have the bug and will be getting ourselves sorted with a couple of bikes and roof rack for Spring so definitely be calling on the forum for advice then, as had my own search and there is so many brands and options, - do think convinced needs to be roof mounted though, just makes sense as best option (to me anyway)
Be nice to have something that allows you to add bikes, but has universal roof box option? any of those out there? as that would be useful for me now.
