This all-round lock offers top security at a lower weight than other chains. That makes the CityChain 1010 the perfect lock for the city - whether it\\\'s an expensive bike or a little scooter you need to secure. Technology: 9 mm hexagonal chain with fabric sleeve to prevent damage to the bicycle\\\'s paintwork The chain, the lock body and supporting elements of the locking mechanism are made of specially hardened steel ABUS Plus cylinder for high protection against manipulations, e.g. picking Automatic cover for the keyhole against dirt and corrosion Transport: Convenient compact transport by wrapping the chain around the seat post (for 85 cm length) For the protected transport we recommend, for example, the frame bags ST 2200 and ST 2250 (for 85 cm length) Tips: The lock can be ordered keyed alike with other locks, all of which are operated using the same key or locking method Very easy handling, because only one end of the chain has to be locked
