You can use Giant's SureLock Flex Cable with a padlock (sold separately) to secure your bike and, if you already own a U-Lock, you can use the cable for additional security by passing it through your bike's wheels as you lock your bike. Other options include securing bikes to car racks, locking up extra wheels at races, and more. The possibilities are endless.
