The generously sized Trailframe frame bag, measuring fifty centimeters in length and with a volume of five liters, easily accommodates heavier and longer luggage, such as tent poles or food, without affecting the bike's handling. The waterproof welded bag is securely attached to the top tube, down tube, and seat tube using sturdy Velcro straps. Its slim design provides ample knee clearance, while an internal Velcro attachment helps to secure the contents and prevent the bag from bulging. The zippered organizer in the main compartment separates smaller items from larger luggage. The very long waterproof main zipper allows for easy packing and unpacking. To make optimal use of the entire frame triangle, the Trailframe L frame bag (edge length fourteen centimeters) can be combined with the Trailframe M (edge length twenty centimeters). At the bottom of the bag, there are two slots through which the top tube attachments of the Trailframe M can be threaded. This bikepacking combination fills the entire space between the frame tubes with a total volume of eight liters. Please note the dimensions.
