There is an informative "FAQ" button in the left column of the home page that may address some of your questions.

Near the bottom of the same page is a button labeled "Previous Issues, Bike and Product Reviews". Clicking it will drop down a long list of articles including one near the top titled "Best Bent?" Read this then explore the other articles for in-depth product reviews.

Hope this helps.
