The Thule 516 - Prologue fork mount bike carrier is an excellent value because it goes beyond merely carrying a bike securely. The Prologue offers many features found on Thule's more expensive fork mounts. The Prologue fits mountain bike disc/suspension combinations with standard 9mm axles and is approved for high performance road bikes with carbon fiber forks. The wheel tray fits mountain bike tires up to 2.6 inches wide, even with high profile rims. Plus the wheel tray is long enough to accommodate long wheelbase bikes up to 48 inches.
The Prologue carrier fits Thule standard bars and Yakima RoundBars right out of the box. With the Xadapt9 the carrier can be attached to Thule's RapidAero, Xsporter and Professional load bars.
The Prologue has got security covered as well, Thule's One-Key System allows you to purchase Thule lock cylinders in a matched set with one key. A single Thule lock cylinder is all that's needed to lock a bicycle to the Prologue rack and at the same time lock the Prologue to the load bar.
Although the Prologue is priced lower than most carriers it still offers a high level of construction material. The head unit of the Prologue is built with high-strength engineering composite plastic and the wheel tray is one piece black powder-coated aluminum.
