I'm thinking about commuting by bike from home to my french classes, but the thought of my bike being stolen worries me and I'd like to hear your opinion.

I think that Onguard's Pitbull 8003 U lock would be good enough for my current situation, since my class only lasts about an hour and my bike would be inside the school.

I paid around $450 for my bike years ago, it's an aluminium road bike with shimano sora shifts. Would you say that it could eye catching?

I'd be glad to hear your thoughts!
