The Interchange Grocery Pannier Eco features Bontrager's Interchange mounting system for easy installation and removal from any rear rack. It's made from tough recycled bike tubes and ad banners, so each bag is one-of-a-kind, and it's the perfect size for a bag full of groceries. It features hidden carrying handles so you can bring it into the store and use it as a shopping bag. Plus, it boasts a zip pocket for your valuables and a zip rolltop to keep your gear dry and safe.
