The Blackburn Ex Grocery Pannier is an ultimate addition to your mountain or road bike. The water-repellent bag features a quick and easy universal mounting system that works with almost any rear rack. It has a robust steel frame inside, which is draped with a water-repellent 250 Denier fabric. The bags can be folded flat when not in use for easy moving and storage. A shoulder strap is included so it can also be used as a simple grocery bag.
