The Catena Chain was ABUS's former office manager’s favorite lock. Being the office's only non city dweller, he had very different security needs than co-workers. He appreciated the Catena Chain for its light weight and versatility. He also loved the peace of mind he got from leaving his bike locked with the Catena when out fly-fishing and ice-fishing.
This lock is sturdy but light and flexible enough to be transported easily by wrapping it around your seatpost.
