Is it possible for you to take the front wheel with you?

Here is a site to show how to properly lock up a bike with a larger U-bolt: http://www.missinglink.org/page/how-lock-bike Then you can use the chain as added protection to the U-bolt to lock the same stuff the same way the U-Bolt is locked.

But keep in mind that any lock can be defeated, and if you are locking it up in a rough neighborhood or over night with very little pedestrian traffic then you may want another option. If the bike is a high value bike then I would consider buying a cheap "beater" for around $150 or so and lock that up instead, and keep your nice bike for weekend rides. There are battery powered angle grinders that will cut through either a U-bolt or a chain lock in less then a minute each. Lock picking is slowly catching on too here in America, it's stealthy, makes no noise, and it just looks like someone having trouble with their key.

And those lock theft warranties are mostly a joke. To get the warranty to pay you first you have to have police report, some cities like NYC won't come out to do a report for a "lousy" bike. Then you have to have detailed photos of the crime scene including general area, lighting, foot traffic, the undisturbed lock, and what you locked it to. Next you need your original purchase receipt of the bike and a recent (less then 12 months, some say 6 month) appraisal of the bike. Then you need the original receipt and box including UPC code of the lock. Then you need the original damaged lock, if it got taken in the heist your screwed. You send all that in and they determine if you meant the criteria for properly locking up your bike, fail any one of those items you get nothing. I haven't yet on any forum I've ever been on heard of a person who had their bike stolen collect the insurance money the lock provisions had...not saying it's never happened, just saying I haven't seen one yet. Even your homeowners or renters policy will have stipulations too, but not as severe, you will need a police report, and original receipt of bike but not a recent appraisal, pics are nice but not needed, and lock receipts to show you at least attempted to lock it up, which is another reason to show crime scene pics to prove you locked it. Then you have to deal with your deductible. Some insurance companies offer floater coverage for bicycles that will cover your bike for anything happening to including accidents, and no deductible, but I think those are a rip off. They charge $75 to $150 per bike per year, so if your bike remains unstolen for 10 years or more you paid out a lot of money.

I'm not sure what kind of security your campus has but campus's use to have high bike theft problems because of the shear number of bikes and the likely hood of finding a nice bike to steal.
