Buy a set of Pinhead Wheel Locks from Amazon:
The Phoenix Metro area is chock full of bike thieves and you need defense in-depth if you want to hold onto that bicycle you love to ride. On recommendation from my LBS I tried out these Pinhead Wheel Locks coupled with a decent quality U-Lock. They seem well-made and like they’d be a good way to slow down a potential thief enough that he moves on to easier targets. The main downside seems to be that if you’re on a trip, lose the key and then need to fix a flat or replace a tire you’re kinda screwed.
