I did the rubber band trick on my Cherrybomb- and it still jumped off of my bag. Someone found it at work after I'd left for the day.
Don't know about any future posters who may bring this thread back from the dead, but I'm not really looking for the Q-R types. I want something that will go on the tab at the back of the rack and stay put until such time as I decide to remove it.
Stay mounts, seat post mounts... I'm afraid that I would damage them in my current bike transportation scheme. On its side in the back of a SUV in the morning, on bus rack in the morning, and on its side in the back of a cargo van.
On a side note, my wife finally got a job
. However, it's second shift, we are car light, and there is no way to reliably share the vehicle. So my normal 10 mile commute ride in the afternoon has been cut to under 2 miles out of necessity to watch the little ones. Never thought my lazy butt would miss those miles, but I'm crankier now than I was when I was riding more.
