Bottom left pic shows why rattly. Ortleib come with inserts to fit smaller rails, might be something similar available to these, else you could tape old innertube to the rack to make the tubing thicker at attachment points.
yeah I know why its rattly, just seems odd to fit such a wide range of tube sizes. Could probably attach it round the toptube of my bike for a snug fit.
Good to know more expensive ones come with inserts, will just bodge this one for now though.
