While compiling information for that document, Lyle came across something that seems to be popular in New York: a bike chain saddle lock, from the seat rail to the seat stay of the frame. Such a device would force a would-be thief to use a chainbreaker to steal your saddle.
I ended up with a spare KMC 410H heavy duty 1/8" chain while trying to get a drivetrain swap going last month. What better thing to do than chain down my beloved Brooks.
Parts: chain of your choice ($10-12 for a new one), old 700c road tube, electrical tape.
Tools: chainbreaker, old brake cable, scissors.
The heavy duty chain is a good choice because it requires a wider than standard chainbreaker. I started by measuring out how much chain I'd need and then put a couple layers of electrical tape on the contact areas. I like my bike's paint, but I suppose this step is optional.
Next, I threaded the chain through the road tube to figure out how I'd go about putting it together on the bike. The tube leaves little clearance, so there's not much room for the chainbreaker. It's also pretty difficult to thread through the thin tube - an old brake cable would make it easier, but I didn't have one readily available.
After a couple of attempts, I ended up squishing the tube up a bit and working the chainbreaker on the straight section.
The finished product looks pretty decent, and is completely functional. I only used 1/3 of the chain, which means I can do two more bikes with the same $10 chain. Word.
When it comes down to it, bike theft is generally one of opportunity. The smartly locked bike will have a better chance of sticking around longer; this saddle security measure is just another way to keep your bike (and its parts) yours.
