The frame mount with quick release is great for its easy on/off, and is super stable. I love the versatility of the system, allowing me to use on multiple bikes.
The Tailfin S Series is incredibly easy to install, and I'm amazed at how strong this thing is considering how light even the Aluminum version is. I would say I want one for each bike, but it's so easy to move back and forth that there is no need!
Honestly the best bike packing product out there. Can't wait for the extension so that I can load the bag properly
