I just recently installed 2 1up roof rack trays on my car and positioned them around 4-5 inches in from the furthest spots they could be positioned from and was wondering how wide most here place them on the bars? I placed mine there thinking it might be best to not have wider handlebar setups stick out past the car but at the same time I probably would have to stagger the bikes a bit if they had similar stem lengths in order for the handlebars to not touch.
