I purchased this, but it didn't fit, so I'm selling it. The following is a quote: A top tube bag has been released from the ultra-lightweight, waterproof racing series designed for ultra-distance and brevets. Using the reliable original Hexalon material, the lid opens and closes with magnets, making it easier. The top lid opens completely, making it easier to check the contents. Specs: Weight: 105g Length: 235mm Height: 100mm Width: 40mm
