Sticky-fingered thieves are identified with a lot of personality traits, but “passive" ain't one of ‘em. The kind of lowlife that'd snag a bicycle and take the bike rack along with it would be called opportunistic at best. So, you need to get aggressive with your bike rack protection and strap it on with the Thule Passive Lock Strap.
This clever Thule strap looks simple, but don't let that fool you. The looping design and round puck are all you need to outwit the craftiest of crooks. Simply loop the nylon coated twin steel cables through your rack and close the puck in your vehicle's trunk or hatch. That's it—another felon foiled! Best yet, since it's from Thule, your Passive Lock Strap is backed by an assertive limited Lifetime Warranty.
