There's no bigger affront to a bike commuter than having her bike stolen. So get a good lock to keep that from happening. Kryptonite’s new Evolution Integrated Chain combines the flexibility of a chain with the security of a U-lock, using 10mm six-sided manganese steel links to foil all but the most determined and well-equipped thief. Add the included $2,250 in bike theft protection and you should have the confidence to lock up anywhere.
