We have a very similar rack made by Swagman:
http://www.amazon.com/Swagman-Cross-...gman+bike+rack and have no complaints about it other than the fact that it's heavy. We got it used on Craigslist, but if I hadn't found I would have been willing to give the Nashbar one a try for half the cost. The principal difference I see between the Nashbar and the Swagman is that the Swagman folds when not in use.
