The POC Ultra Top Tube Bag 0.7L sits behind the stem for the items you need one-handed while moving. It suits long-distance riders who are tired of fishing around in jersey pockets. The long, thin shape keeps it clear of your knees, and multiple fastening points, including a bolt-on option for frames with mounts, hold it completely still. A long zip pull and a gently curved profile let you open it and find what you need with one hand on the bars. Internal mesh pockets keep small items sorted, and the material is fully waterproof with welded seams. Key features 0.7L capacity, fully waterproof construction Bolt-on or strap mounting options Slim profile that does not interfere with pedalling One-handed access with long zip pull Internal mesh organisation pockets Check whether your frame has top tube bosses before choosing a mounting method.
