How to Pack Bicycle Chains for a Flight
Step-by-Step Traveler Decision Checklist
- 1 Placement Decision: Cabin: YES | Checked Hold: YES
- 2 Packing & Protection: TSA gave bicycle chains their own green entry, so the drivetrain is not your problem — the rest of the tool roll is. Chain whips and long wrenches fall under the seven-inch tool rule; anything longer goes in checked luggage. Degrease and bag the chain before packing: black paraffin on the checkpoint tray gets you remembered, and a clean chain X-rays as exactly what it is.
- 3 Checkpoint Protocol: Keep packed securely inside carry-on luggage.
- 4 Airline & Authority Boundary: Check airline baggage policies for individual carry-on size and weight limits.
