Currently, I have a Kryptonite chain lock and a small Sunlite u-lock. Due to its size, the u-lock is only capable of going around the back wheel and seat tube, relegating the chain lock to the front wheel, fork, and the object that the bike is being attached to.

However, I learned a while back that the rear wheel is more valuable than the front. I would much rather use the chain on the rear wheel.

This leads to the question at hand. Would it be safer to get a larger u-lock to use in the front so that I may use the chain lock in the back, or get locking skewers and forgo locking the front all together.

Actually, it a 3rd option just dawned on me. If I were to get locking skewers, I could still forgo locking the front and still get a larger u-lock for the back. That way I would only have to carry a u-lock instead of an 8 lbs chain. Just a thought.

Any suggestions? I am in NYC and will be commuting to a mostly public college campus, if that matters.
