The Bike Box dimensions determine what you can carry. Use this guide to guide your selection.
Width: this dimension determines what will fit in the bottom of the panniers.
Overhead: the length from the bike rack to the top is called the overhead. If you need to haul large things they will go in this section.
High and Low Length: the pannier length determines the maximum length of your cargo. The larger the difference between the high and low lengths, the easier it is to nest multiple bike boxes (for storage)
Cant: the angle of the box side to the bottom is called the cant. The greater the cant, the easier it is to nest multiple bike boxes.
