Sorry if this is wrong forum - there's a lot of forums here, and this looked most appropriate since comuters have to lock up their bikes somewhere.
I'm not what you would call an "avid" Bike Rider - but they cancelled the express bus to my college, so now I would have to leave two hours early to get to class on time - unless I ride my bike, which I've been doing. First day test run, 38 minutes w/o backpack. Now in second week it's 30 with backpack - much better than bus commute with transfer and long wait. And the commute is probably good for me anyway.
I park by the math building, they have a bike rack there that only I seem to use - but unlike the main back rack, it is somewhat protected from the elements (it is covered) and all my classes are up there.
Yesterday between classes I was sitting on the grass - and some skinny speed freak looking lady came out of the math building, saw my bike, and then went to take a look. I saw her inspect the U-lock holding the rear tire to the bike rack. I watched her head follow the chain going through the rear tire, my seat, the frame, and the front tire. Then she looked back at the u-lock holding the bike, looked around her - and saw me standing with my helmet staring at her.
She then said "nice bike" and walked away.
I'm guessing she knows something about my locks that I don't know - and I really don't want this bike stolen - it's the only one I have, and I can't afford to replace it. What kind of chain or lock should I use?
The U-lock is a master lock, it's not that kryptonite one that apparently can be picked with a pen - but I don't know if this can be similarly picked. The chain is a kryptonite combination lock that was recommended to me by the bike shop where I bought it.
It's not an expensive mountain bike or anything - it's a diamondback wildwood, about two years old, with a custom fork on the front (the bike shop replaced all diamondback forks with these out of policy - they supposedly are better) - but it's my only bike, and I don't want this ***** (or someone she knows) to steal it easily because they know something I don't.
