Title: IT'S A PIP!
Review: My partner got one of these, and now I'm buying one too. It's roomy, easy to install, and a snap to slide on and off the rack. You can stash essential bike tools, rainwear, snacks and such that may come in handy on a long ride or, in my case, for commuting to work. The rack is absolutely stable on a steel or alloy bike post. One caveat: don't attach it to a carbon seat post; that material is not designed to withstand the forces the clamp exerts when you hit bumps and such.
