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 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.
Step 3: Secure the fork
Step 5: Secure the seat
Step 6: Coming together now...
Before you lock it, put the end of the small cable from your seat on this U-Lock too.
