When we step away from our bag-laden bike for coffee and treats at a trailside cafe, it's easy to feel like we're stepping away from our most essential pieces of gear. That's why it's key to lock our panniers up with the QL2. 1 Bag Anti-Theft Device. It's a pair of steel cables with loops for installation in bags with Ortlieb's QL2 and QL2. 1 systems, and it protects our bike and motorcycle panniers from theft so we can feel confident about leaving our rides locked up outside.
