Size: 85cm length; Weight 1.6kg Review: No mechanical problems, does the job - It's pretty good, does the job and there are no mechanical problems, no rusting and no seizing up so far. Review: Reassuringly solid, but mechanism can be sticky - Solid and chunky, good for this price point. Have been using for 3 months with no issues. However just recently I've noticed the lock becoming reluctant to open. I've applied grease to the mechanism which seems to help a little, but probably 3 in 10 times, the lock will rotate but not disengage, requiring considerable force and several attempts to get it to open. Less than ideal when fumbling around in the dark on a rainy morning. ## Features - The bicycle lock measures 85cm in length and weighs 1.6kg; This Kryptonite bicycle lock is a sturdy, flexible and compact chain lock - New end link design secures chain to hardened deadbolt - Hardened Deadbolt Dedsign Provides Extra Holding Power ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B005YPK7V8 | | Best Sellers Rank | 7,249 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) 16 in Cycling Chain Locks | | Brand | Kryptonite | | Colour | Black | | Control Method | Touch | | Controller Type | Key Control | | Country of Origin | United Kingdom | | Customer Reviews | 4.5 out of 5 stars 7,544 Reviews | | Finish | Painted | | Global Trade Identification Number | 00720018000853 | | Included Components | Locks | | Item Dimensions | 38 x 63 x 464 millimetres | | Item Type Name | Accessories | | Item Weight | 1.41 Kilograms | | Item dimensions L x W x H | 38 x 63 x 464 millimetres | | Lock Type | Deadbolt | | Lock type | Deadbolt | | Manufacturer | Kryptonite | | Manufacturer Warranty Description | 1 year manufacturer. | | Material | Plastic | | Model Name | GK000853 | | Model Number | 720018000853 | | Number of Pieces | 1 | | Part Number | 000853 | | Recommended Uses For Product | CYCLING | | Recommended uses for product | CYCLING | | Shape | Square | | Smart Home Compatibility | Not Smart Home Compatible | | Special Features | KRYPTONITE Keeper 785 Integrated Chain-32' (7 mm x 85 cm) Unisex Adult Chain, Black, 7 | | Special feature | KRYPTONITE Keeper 785 Integrated Chain-32' (7 mm x 85 cm) Unisex Adult Chain, Black, 7 | | Style | One size | | UPC | 720018000853 | | Unit Count | 1 unité | ## Product Details - **Brand:** Kryptonite - **Item dimensions L x W x H:** 38 x 63 x 464 millimetres - **Lock type:** Deadbolt - **Material:** Plastic - **Special feature:** KRYPTONITE Keeper 785 Integrated Chain-32' (7 mm x 85 cm) Unisex Adult Chain, Black, 7 ## Images ![Keeper 785 Bike Chain Lock, 2.8 Feet Long Heavy Duty Anti-Theft Bicycle Chain Lock with Keys for Bike, Motorcycle, Scooter, Bicycle, Door, Gate, Fence - Image 1](https://m.media-amazon.com/images/I/81Yn1W5w1ZL.jpg) ![Keeper 785 Bike Chain Lock, 2.8 Feet Long Heavy Duty Anti-Theft Bicycle Chain Lock with Keys for Bike, Motorcycle, Scooter, Bicycle, Door, Gate, Fence - Image 2](https://m.media-amazon.com/images/I/710tHu9KoCL.jpg) ![Keeper 785 Bike Chain Lock, 2.8 Feet Long Heavy Duty Anti-Theft Bicycle Chain Lock with Keys for Bike, Motorcycle, Scooter, Bicycle, Door, Gate, Fence - Image 3](https://m.media-amazon.com/images/I/71zQFqRfm5L.jpg) ![Keeper 785 Bike Chain Lock, 2.8 Feet Long Heavy Duty Anti-Theft Bicycle Chain Lock with Keys for Bike, Motorcycle, Scooter, Bicycle, Door, Gate, Fence - Image 4](https://m.media-amazon.com/images/I/81wWYWkb80L.jpg) ![Keeper 785 Bike Chain Lock, 2.8 Feet Long Heavy Duty Anti-Theft Bicycle Chain Lock with Keys for Bike, Motorcycle, Scooter, Bicycle, Door, Gate, Fence - Image 5](https://m.media-amazon.com/images/I/91viAjGXQtL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Questions & Answers **Q: How long is this chain is it 85cm long** A: If you count it as a loop (From the lock to the ring - the exact circumference) it is 85cm long.
