I live in Chicago, and want to make sure it's secure. I've heard of people using the "Sheldon Brown" method instead, and locking the back wheel, but it still seems like the wheel could be cut off. Also I know people suggest locking the back wheel with the u lock instead of the cable since it's more valuable, but on a fixie with no gears, is it really any more valuable?
This is usually the method I use. Is this proper?
If not, and I should use the sheldon brown method? Should I lock part of the frame as well as the wheel? I see a lot of people just locking the wheel.
