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.
Step 2: Secure the front wheel
Make a loop through the front wheel with the cable lock.
Step 3: Secure the fork
Take the cable that you just looped through the front wheel and go through the fork crown and arch, this will deter people from stealing you nice front shock.
Step 4: Secure the frame
Loop the cable through the front triangle of the frame.
Step 5: Secure the seat
Seats are expensive these days. So we'll loop a cable through the seat rails, this will help to deter people from stealing you seat and post.
Step 6: Coming together now...
Now run the long cable from the frame/fork/front wheel through your rear wheel and to the U-Lock that connect the rear triangle to the bike rack.
Before you lock it, put the end of the small cable from your seat on this U-Lock too.
Step 7: Chain Lock
Now I put the New York Chain Lock through the rear wheel, rear triangle and main triangle of the bike and then secure that to the bike rack.
