By default, there is no system for holding the pannier against the luggage rack, for two reasons:
- The pannier support consists of two layers of fabric enclosing a foam panel. This padding protects your fragile cargo from the aggressive parts of the luggage rack (a guitar case, for example) and avoids the noise it might generate when banging against the rack. It's no big deal if the pannier swings away from the bike on a little bump, so it's all done in silence!
- The additional straps supplied allow this to be done if necessary, in the case of a very high object that could topple over the luggage rack, for example.
However, a chain of straps on the bike-side rack allows you to add a Velcro-type fastener, colson collar or similar, to be passed through the uprights of the luggage rack.
