To keep your favorite Vaude pannier secured tightly to your bike rack, we recommend the Locking Vaude QMR Upper Pannier Mounting Hooks. The quick mount release (QMR) locking system features two clips that can be locked to the upper rails of your bike rack with two easy clicks. To unlock the system and remove the pannier, you simply lift up on the handle of the pannier to release the lock. To secure the locking QMR upper pannier mounting hooks to your pannier, you will also need the Vaude QMR Locking Hooks Backing Plate. The attachment screws for the backing plate are integrated into the locking QMR upper pannier mounting hooks. The hooks come as an integrated set of two locking hooks and the release handle.
