Bicycle thieves are shifty, crafty sorts. They’re the kind of guys who invest way too much time and effort into stealing things they could’ve saved up a few bucks for and bought on their own. So the war against them is always on, and the latest weapon we have is Kryptonite’s WheelNutz.
Using a gravity locking system that secures to your front wheel, WheelNutz provide an internal “lock-out” function that can only be removed by turning the bike upside down 180 degrees, a feat normally made impossible by your primary bike lock. The installation is easy, as you only need a 15mm wrench (no keys), and the weather protective coating will keep them from corroding during nature’s worst. Score a pair for $31. [Purchase]
