Hey guys, for what it is worth, here are my thoughts on the Tsukayu quick release strong bags with the brackets shown in this picture:http://tsukayu.com/QuickDetachableStrong.html
LOVE the way the bags look. Plenty of storage space for a long solo trip. Would need to consider a rear rack of some sort if I was going on a long trip with my GF or have her hold a duffel on her lap like GoStr8er's wife does.
Not a fan of the brackets.
While I was initially delighted by how quickly (seconds) you can take the bags on and off with them, and by how clean the bike looks with the bags off, I am sorely disappointed with the design and/or quality of the metal alloy they are made out of. They had deformed by the second day of my Texas to Virginia highway-only trip. The bags flap around a lot with these brackets because they are only held onto the studs that mount on the sides of the rear fender by a few millimeters of lip on either side of the bracket rail that is mounted to the bags. This translates to immediate deforming after a day of riding over dips and expansion joint cracks on bridges (standard highway day). I even made a point of researching the max load limit for the bags before setting off on my trip (20 lbs). This is a bit annoying since the bags themselves with the brackets are probably pretty near 20 lbs. to begin with. I filled them with clothes only and bungeed heavier stuff to the rear fender (with color-matching hand towel underneath of course - ha!).
Fortunately, the bags have not fallen off. The main annoyance now is that it is nearly impossible to get them on and off of the bike because they are so deformed. Not sure what I am going to do because while I was still in the states riding the thing they got worse with every passing day pretty much despite riding with them empty sometimes. Am now looking into a more permanent bracket solution because they are pretty useless for real touring and errand-running, which is what I got them for.
This is just one of those things you learn by buying and trying, I guess, but I thought I would try to help others out who may be considering them.
