    Kryptonite Lock

    Well impressed with this cable lock. Physical strength gives you the impression that you can have confidence that it will do the job and deter anybody from having a go. Price good and would recommend this product.

    Kryptonite Cable lock

    I bought this for my new road bike to secure it whilst i'm at the gym. Not the lightest on the market but as i'm not intending on carting around for miles it doesn't matter, the lock is of good build quality and the cable size should stall any potential thieves, recommended!

    Lightweight

    Cant fault the build quality but I'm not sure about it being lightweight it depends on what you're comparing it to and I hadn't checked what 15mm cable looks like so it felt quite heavy to me against my old thin cable lock. I wouldn't like to carry this around to often but it does look formidable.

    Cable lock

    This is very good cable lock from kryptonite who are one of the leading brands that extends to two bikes easily. It is suprisingly light given the length and wide cable diameter. Two keys included with serial numbers a very good price at around £15 from Tredz who I have found to be very good bike shop online

    Cable Lock Guide

     

    Overview

    For use in low to medium crime areas

    Cable locks are a lightweight, flexible deterrent while you nip to the shops, or relax in the café. These affordable locks are best used in rural and low crime areas to make thieves think twice about lifting your bike. They’re not for locking your bike in high crime areas or for overnight storage.

    Many cyclists use cable locks as a secondary locking system to secure components like the front wheel or saddle. A common setup is a D-lock around the bike frame and rear wheels then a cable lock to secure the front wheel to the frame. A cable lock is also a lightweight option for securing your bike to your car bike rack.


    Construction

    Cable Material

    The cable itself is usually made from twisted steel. It’s a lightweight and sturdy material for its size, making it a good choice for portable security. More premium locks use high tensile hardened steel which is less flexible but stronger.

    Some brands will also use a layer of steel rollers or toughened steel shells covering the steel cable. This will reduce flexibility and add weight, but they’ll be much harder to cut through.

    Cable Diameter

    Cables will vary from lock to lock. They can be as thin as 3mm, for a super portable and lightweight design. The sturdiest cables can be 20mm thick. The thicker the cable, the tougher it will be to cut.

    Cable Length

    Cable locks can range from under 1 metre up to 2 metres. The length you chose should depend on how and where you’re likely to be securing your bike.

    If you’re fixing your bike to a bike rack, then a length under 1 metre will be OK. If you are locking your bike to an obscure object, or you’re locking multiple bikes together, then you’ll want a cable between 1.5 metres and 2 metres.

    Locking Mechanism

    Key Lock

    Keyed locks usually come with two or three spare keys. This is great in case you lose a key, as you will always have a spare.

    Some brands like Kryptonite offer a KeySafe programme where they will ship spares to you once you have registered your bike lock.

    Combination Lock

    Instead of keys, there is usually a 4-digit combination to open the lock, meaning there are 9,999 different possible combinations.

    A combination lock is a great choice for those who are forgetful or simply don’t want to carry around extra keys.


    Weight

    These bike locks are the lightest you can get. They’re much lighter than a chain lock and are lighter than most mini D-locks. The heavier the lock is, the thicker the steel is used within, and the more secure it will be. Cables can range from under 500g up to 1.5kg.

    Lighter weight helmets tend to offer more comfort

    Frame Protection

    Most cable locks will come with some form of covering such as canvas or vinyl coating to help protect your frame from scratches and damage.
