It uses velcro to connect to the pannier. Not really useful if it is going to be continually removed as the bottom straps can be a pain to get to if it is a tight fit for between the pannier and the tyre/mudguard. **Q: Does this have drop-down side bags?** A: Yes and they work well **Q: Would a laptop fit in this bag** A: Hi, this depends on the size of your computer, but but we would not like to advise you to put your valuable objects in this pannier bag, because it may cause damage.
