Hi all, I have a C-Line and hoping to get a G-Line soon. Was curious if a XS North Face duffle would easily strap / fit on a rear rack for either with appropriate straps? I’ve not bought a rack yet and not seen one in the flesh so hard to judge. Would like to make use of an existing bag I have for additional bike packing capacity than buy another bespoke bag if it can be avoided (I have a front Brompton bag). Any advice appreciated!
