no one picks locks, they just cut them. has anyone actualy seen a bike lock get picked?

but as mentioned above avoid the barrel kind, they are prone to jamming up. my girlfriend is starting to have issues with her kryptonite keyed lock, i've had a basic 4-digit cable lock for 3 years now. it gets sticky so i just give it some WD now and then, but hasn't broken yet.

im a fan of the cable lock since you dont have to take the front wheel off to lock it with the back. and i can lock up to trees and stuff that are bigger around than a Ulock. carrying a ulock and a cable is silly in my opinion when the cable is going to be the weakest link and targeted first by a potential theif. just get a thick cable or chain.

ive poped a lot of both kinds (for others on campus, using a pair of bolt cutters), and trust me, how and where you lock up is much more important than what you lock up with.
