The Midloader is constructed from lightweight, durable, water repellent, and stain-resistant materials, so they'll last a long time and withstand wear and tear. It's designed to fit in the unused space on your frame and carry your heaviest essential tools and gear to keep from being stranded in the middle of nowhere. With its hook and loop fasteners, it mounts and removes quickly while the two water resistant zippers offer easy access to all your belongings from either side.Lightweight, durable, water repellent and stain resistantWater resistant zippers for easy access to contentsStraps securely to bike frameBag attachment: Hook and loop fastenerCapacity: 4.5LDown tube diameter: Fits ø38 - ø70 mmTop tube diameter: Fits ø45 - ø66 mmSeat tube diameter: Fits ø28 - ø60 mmMax load: 6.5 kg / 14.33 lbSize: 46 x 12 x 6 cm / 18.1” x 4.7” x 2.4”Weight: 195g / 6.88 ozMaterial: Polyethylene / NylonColour: Black
