Interchange Rear Trunks

When used in conjunction with an Interchange compatible rear rack, these rear trunks install and remove in seconds, without the need for tools. Designed with an aerodynamic shape that helps fit under a larger range of saddle heights, the Interchange Rear Trunks are masters of versatility, thanks to convenient expandable design. Three sizes available, some with zip out panniers.
