I'm traveling to the US so I need something strong and durable for my gas cylinders. This holder is perfect! I've ridden it over 10,000 miles on all types of roads, including "bumpy" dirt roads, and it's fine! I added more security by threading the chain through the gas canister handles and putting a lock on both ends to keep it from coming up. As for the bracket itself, I used self-tapping screws on both the bottom and one side to keep it from moving and lifting the whole thing up.
