Product Description

The Kryptonite Evolution Series 4 1090 chain lock is a truly exceptional mid-range security system for moderate to high crime areas. Each hardened triple heat-treated boron manganese steel chain is 10mm thick and six sided - you won't find better at this price point.

Nylon webbing is a great feature on the Evolution Series 4 as it protects your paint work from getting scratched and helps make portability easier. The chain lock comes with 3 steel keys, one of which is a lighted LED key - making night time locking much easier.

Features

  • The hardened triple heat-treated boron manganese steel chains include 10mm six-sided links
  • The integrated chains secure with a new patent-pending integrated Evolution series 4 lock head
  • This innovative series of chains also feature a patent-pending pin-less design which secures the chain to a hardened deadbolt and allows for no weak leak in the chain due to extensive holding power of the link itself against attacks
  • Chains are enclosed in a nylon-webbing sleeve to protect paint from scratches and allow for easy portability and tight coiling during storage
  • Comes with 3 stainless steel keys including a lighted LED key with replaceable battery and 2 new, ergonomic ’I’ keys
  • One key is lighted for easy access at night; replaceable battery insures that light can be used as long as the lock. The new ’I’ keys make opening a disc-style cylinder much smoother

Sold Secure Gold for a great price

Comes with 3 keys, one has a blue light in it. Its long enough to use with my floor anchor to hold down my bike, which needed sold secure gold locks to be insured for theft. They have a theft insurance with the lock that seems quite cheap too, and a key replacement service. I'm impressed. Got a good deal too. Full price would've been a bit too high.

Nice and heavy

Feels solid, easy to handle. A bit heavy, but I'm guessing that is unavoidable for this level of protection.

Perfect for the Job!

Bought the 1055 (55cm) initially, but as it wouldn't fit around a lamp post I got the 1090 which is fine. Both are 'Sold Secure' gold so cover me in terms of bike insurance requirements. My only slight criticism is a fairly sizeable jump in price just for a bit of extra chain length. But overall, very pleased with it.

Kryptonite evolution series4 1090

This is the second lock that I have purchased from the Kryptonite company,and as usual the build quality is first class. Very heavy duty but great for securing to a solid object. Good value for money from Tredz.

Heavy, Sturdy, Clumsy

Great item, not as long as I imagined it to be, but still works fine for locking to larger objects. Was considering buying the smaller (55cm) version of this lock, but lucky that I didnt, I cant imagine it being any use even shorter. Overall, heavy, bulky item which should act as a good deterrent to would be thieves. The key doesnt operate very smoothly, you have to wiggle it to get it in all the way. With a bit of wear it will hopefully get better and not worse.

Excellent lock, weighs a ton

Just had it so not really put it to the test. It's much bigger and heavier than I was hoping though I realised is was going to be chunky. It really is a beast and seems very secure. I just haven't worked out how to carry it on my bike yet!

Chain Lock Guide

 

Overview

For use in medium to high crime areas

Chain locks are flexible, tough and come in a range of lengths. They opening up a range of versatile locking options that you don’t get with other types of lock. With a chain lock, you’re not limited to fixing your bike to racks and lampposts, but also trees and other oddly shaped objects.

Chain locks are made of two parts, the steel links that create the chain and the lock. The lock may be integrated into the chain, a separate padlock or even a mini D-lock.

A burly chain lock can withstand a range of attacks from crowbars to powered tools. However, the trade off is weight. These are the heaviest bike locks that you can get, with some models weighing over 7kg. The heavier the chain, the stronger the links and the more protection you get.


Weight

Portable Chain Hiplok

Portable Chain:
1kg – 3kg

Lighter weight chain locks under 3kg can be wrapped around your seatpost or frame and taken with you on your morning commute. These locks are more practical for daily use, however, will not offer the same level of protection as a sturdier chain.

Thick Knog Chain Lock

Stationary Chain:
3kg – 7kg

Locks weighing over 3kg are not practical to carry around with you. They do make a great stationary storage solution for your garage or shed, where the chain can be permanently fixed in place. Match a chain lock with a ground anchor for the ultimate protection for your bike at home.


Material

Chain links are usually built out of steel. However, premium chains will be constructed from hardened steel. By tempering the steel during forming, it becomes harder and less brittle. This makes it much tougher to cut through the links without serious equipment and time.

Triple heated Boron Manganese steel is exceptionally resistant to cutting style attacks while remaining ductile.

Thick Knog Chain Lock

Link Thickness

Small diameter d-lock

12mm & Under:

Chain links under 12mm can be cut with sustained effort with standard bolt cutters if the conditions are right.

Tip: Lock your bike in an awkward position to make it harder to use bolt cutters.

Medium diameter d-lock

13mm – 15mm:

Only the heaviest duty bolt cutters will be needed for these links.

Remember, chain links need to be cut twice to break the link. This will take skill, time and effort.

Large diameter d-lock

16mm & Over:

Even the best hand operated bolt-cutters will struggle to tackle these links.

Tip: Keep your chain and lock off the floor. Freeze spray and a hammer strike can compromise the best chain locks.


Locking Mechanism

The Lock

You’ll find most chain locks either come with an integrated lock or a separate padlock (or mini D-lock). A chain is only as strong as its weakest link, so make sure the lock is tough enough for your needs.

Look for double deadbolt locking mechanisms that make it much harder to pick or drill the lock open. The thicker the shackle diameter on the padlock or D-lock, the tougher it will be to cut through.

Construction

Chain Length

Most brands offer varying chain lengths to suit your needs. Consider where you’re likely to be locking your bike.

Lengths under 1m will be useful in tight areas such as locking your bike to a rack, fence or post. 1.5m – 2m chains are useful for locking multiple frames to one spot in your garage (you won’t be carrying these length chains with you as they’re too heavy).

Sold Secure Rated

A great way to determine the quality of a bike lock is to see if it is Sold Secure Rated. This is a third party, UK independent rating system for bike locks.

Sold Secure Bronze

Coverage: Up to £500

Sold Secure Silver

Coverage: Up to £1,000

Sold Secure Gold

Coverage: Over £1,000

An approved lock is graded as Gold, Silver or Bronze. The rating is chosen by how long it takes to break the lock and the tools needed to break it. If you're planning on insuring your bike, many insurers will state you need a Sold Secure rated lock to make a successful claim.

These values vary between insurance providers so check the terms and conditions of your provider.


Frame Protection:

Metal chain links can quickly scuff your paintwork. Look for chain locks that come with plastic or canvas sleeves to protect your frame from damage.

It’s also worth choosing a lock (whether integrated or separate) that has rubberised or bump proof shackles and crossbars to ensure your paintwork is safe.
