Depends how valuable your bike/components are. Anything deluxe will attract a thief so trick wheels/seatposts/frames are a target. 2 x locks, 1 for the front wheel and one for the rear and put through the frame as well and as tight as possible to prevent the locks being cut/levered. Quick releases on wheels can be substituted with locking quick releases and you can use removable seat posts using a quick release. Ideally a store room, your office or a secure facility are the best options. My bike is behind a locked door to which only I have the key
I know a few people round here (heavy bike use and therefore heavy bike theft rates) who purposefully make their bikes look less valuable than they are, spray painting them badly to cover up the make for example, using zip ties on all the parts to make it a faf to nap something by an opportunist thief and stuff like that.
Well, first trip out with new bike tonight to university swimming pool (not a student but I'm a member of their pool). Bought a bi-tek lock from sainsburys today which wasn't expensive but looks heavy duty. I locked it to had the bike rack thing which is right outside the door of the swimming pool. Totally paranoid while I was swimming and when I went back to get it I spike to someone who was unlocking his bike. He said that his previous bike had been stolen from outside another university building - they had cut through the lock!! I was getting myself organized and a guy came round the corner on a bike with someone walking behind him. He glanced at my bike, said something (that I couldn't hear) to the one on foot and they both turned and went back round the corner. I know it was probably totally innocent but I'm even more paranoid now!
I think my bike should be ok at work. It will be in a bike shelter, on work grounds, locked up. I think it's kind of overlooked by some offices. Actually, come to think of it, the bike shelter is attached to the smoking shelter and going by how often the smokers in my office go out for a'break', I think there will be plenty of people about.
Def think about where you lock it up, CCTV is good but somewhere busy if possible with lots of foot traffic. We have a few locks, expensive but worth it and we lock bikes together/to things and through wheeksy with quick release our tossers nick your wheels!
Oh God, you've got me paranoid now! No idea about bike parks, bike locks or anything. It's 20 years since I had a bike so I guess things have probably changed slightly since then. We've major roadworks starting between my house and work which will cause traffic mayhem for at least 6 months which is why I've bought this bike. Got some cycling leggings today to save my bum!
