Stolen bike or any of its parts should be a celebration: time to get a new one! Woo! Its such a long and daunting process for parts to breakdown on their own = (
having had my bike stolen, that's one of those comments that makes me want to punch you (not really, but yes. ;P)
...however: that does not mean you should tie your bike up with a shoe-string. Like someone mentioned earlier: any lock can be hacked (Kryptonite evolution take 4 minutes on a battery operated saw and Fugghetaboutit takes a whole 6 minutes of sparkflying action).
So if you are in a store for 5 minutes, you have no bike w/ the Evo but with the NYF, you get the opportunity to beat down the thief- that's worth the $20 difference alone.
that's why they sell locks for every budget. If you can't afford a NYF compared to a Series 2, get what you are comfortable with spending. If you are spending at all, why not get the best you can for your money?
Neistats are really getting into cycling aren't they? Good looks
