Title: What the manufacturer doesn't tell you....
Review: As at least one reviewer has noted, it doesn't fit many bikes. Before buying, look at the "neck" of your bike's frame above the crossbar and just below where it meets the rotating shaft connected to the handle bars. If this stationary "neck" of your frame is not at least 1" long, forget this product. Most mountain bikes have virtually no neck at all, so check before you buy!
