Hey now!!! The OP evidently wants a doohickey that keeps his ride vertical when stationary. The "lean it against something" and the "buy a heavy metal bolt-on" options were obvious, and I'm disappointed in those who could think of nothing better.
My lightweight, high tech suggestion is the Click Stand. I use it when I'm touring, but not when doing the regular riding I do. For regular rides I just lean it against something. I'm not affiliated with Click Stand. I just like the product.
