Hi, Im starting a new job in 2 weeks and im going from a nice back road 13 mile each way commute, to a straight through town 5 or 6 mile commute. Currently commute on a specialized allez and leave it locked in the office at work where its safe. However, I went to have a look at the new place today and cant see anywhere to lock to except a huge railing near the car park that I dont think a D lock will fit around. There were a few bikes there chained up. Keeping it inside was a definite no apparently. I guess my question is do I need to just get a hefty chain? I could always leave it at work if its too much to carry, i usually carry a fahgettaboutit d lock around. I was also looking at some noose chains, anyone used these before? Never really had to lock my bike anywhere out of sight for any long period before. Thanks in advance for any help.
