I don't typically engage in any form of social media- forums included- so I don't know if I'm even posting correctly. But, I have a Topeak Explorer rear rack with it's MTX mounting track, and I can't find anything which will permit me to custom build a detachable platform for strapping my tent , tarps and mat to to allow for easy access to my panniers (Ortlieb Back Rollers). The only thing I can find is Topeak's trunk bag that is compatible with the track system. I DON'T want the trunk bag. All I need is an adapter that will allow me to use the quick release track. Any suggestions would be a huge help.
