This expedition-worthy rack is made from 4130 chromoly, so it's tough, light and easily repairable in the field. It's also height-adjustable, so you can get your center of gravity as low as possible for a stable ride. The provided stainless steel hardware enables you to attach your rack to virtually any frame with 26-inch, 700c and 29-inch wheels. And, it hauls up to 80 pounds of gear and is powder-coated to protect it from the elements.
