This is an ABUS chain lock. I no longer need it because I got rid of my bicycle. The length is about 90cm. The chain is thick to medium thickness. The weight was 740g. There is only one key. It was used outdoors, so there are signs of use and dirt. As far as I can see, there are no tears in the protective cover or scratches. - Brand: ABUS - Color: Red, Yellow, Black - Type: Chain Lock - Connection: Metal Thank you for looking. #bicycle #cityriding #roadbike #fixedgear #bike #lock #key #theftprevention #security #safety
