Well, bar bag. It doesn't arouse great emotions, it will hardly be used for another trip when it doesn't really fit the phone and it's not very convenient even with those who are snacking.
Suitable for a wide range of wheels. Fastening straps long enough. Slightly rigid zipper.
Attaching to a thinner tube is a bit awkward, but it does matter.
The materials feel a bit stiff and the zippers therefore run a bit smoothly.
