Hmm…. I can easily and solidly strap my MSR Hubba & camp chair or my Lunar Solo & camp chair onto my Aeroe handlebar cradle.
I’ve seen people with these new MSR, Big Agnes, and Sea to Summit “bikepacking tents” and they all seem do a mediocre job at best of securing themselves to handlebars.

I’m also all for DIY and DIY solutions and have made offset mounts out of solid steel or aluminum tubing…
