The weather is nice, so I have been mountain biking before work. The trails are empty, the world hasn't caught up with you yet and beat you down, so you have no excuses not to ride...
This presents a challenge in that I can't bring my bike in to the office.
This instructable will show you how to lock your nice bike up at a bike rack with a little bit more security than you might use for your commuter bike.
Step 1: Parts
I will assume you already commute to work regularly by bike... I leave a Kryptonite NY chain lock at work on the rack outside.
I will bring with me in my camelback(actually a deuter bag but who cares...) a Kryptonite NY lock and two cables.
I use the short kryptonite cable for the seat, and a 6 foot long cable for the front wheel.
