Product Description

Sold Secure Silver rated

Featuring a simple, strong and attractive design, the new Abus Ultra 410 is the ideal entry-level D-lock and complements the Super Ultimate and Ultimate line-up. Its simple design conceals a number of high-tech advancements in security including a new double-layered key with decoy cuttings and a cylinder with special wafers, which make this lock virtually impossible to pick with conventional methods. Every variant is Sold Secure Silver certified.

The 12mm thick double bolted, hardened steel shackle extends all the way through the lock body giving excellent protection against cutting and torsion attacks in a simple yet innovative design. The Abus Ultra 410 mini D-lock uses a very easy to mount, rattle-free frame bracket and comes in a full range of mini and standard sizes, with or without additional extension cable.

Review

“The Ultra 420 has a 12mm round steel shackle that's more than large enough to secure frame and rear wheel to any bikes stand. The key cylinder has been refined to make it even harder for anyone to pick the lock.” – London Cyclist

Nice small lock

I wanted a small lock for a small folding bike. This D-lock provides enough room to get around a frame and a Sheffield stand positioned right next to each other. It has a bracket to store on the bike, which cleverly can't be undone while the lock is stored on it. The bright green colour won't be appealing to everyone. The D-lock itself seems to feel around the same weight as a mug of tea. The cable that comes with it is useful for an additional measure to put off thieves.It's my third Abus, for different applications, and I expect it to be as reliable as the rest.

D-Lock Guide

 

Overview

For use in medium to high crime areas

A D-Lock (also known as a U-Lock) is the most practical bike lock you can get for peace of mind when you’re at the shops or in work all day.

D-Locks are ideal for bike security as they offer strong protection against a range of attacks. While some of these locks will be heavy, they are much more portable than a chain lock and far tougher than a cable lock. D Locks are very stiff meaning they’re easy to fit around your bike and a stationary object.

Most D-Locks come in two parts. You have the shackle made of steel or hardened steel with a diameter up to 18mm. The crossbar contains the locking mechanism and you slide the shackle into the bar and turn the key to fix it in place.


Size

D-Lock Size

A standard D-Lock will easily fit around your bike and normal bike racks. If you have a particularly wide framed bike you can get wider and longer shackles. Alternatively, there is also a range of mini D-Locks are that specifically for use just with a standard bike rack. You won’t be able to fit your bike around a lamppost with a mini.

For security, it is best to get a D-Lock which will fit your frame and stationary object without leaving too much internal space. A common way for thieves to defeat your D-Lock is by slipping another object like a crowbar inside the shackle and leveraging with enough force to break it open.

Shackle Diameter

When choosing a D-Lock, the thicker the shackle diameter is, the more secure it is (especially against bolt cutters). However, the trade off is weight. Some very sturdy D-Locks can weigh over 2.5kg. One tip is to lock your bike high on the frame and off the ground to make it harder to use bolt cutters.

Small diameter d-lock

13mm & Under:

Under 13mm shackles can be cropped with most standard bolt cutters while some determination.

The quality of steel used in the shackle can increase the time this takes. Ideal for quick visits to the shops.

Medium diameter d-lock

13mm – 16mm:

At this diameter it becomes much harder to crop a D-Lock with a standard bolt cutter.

Good for locking to the bike rack outside the office.

Large diameter d-lock

16mm & Over:

With a shackle this burly only the largest bolt cutter jaws with sustained effort with crack through.

It’s unlikely a thief will have the time or tools to cut through. Great for locking your bike overnight.


Locking Mechanism

Deadbolt Locking

Most D-Locks will now use a deadbolt locking mechanism. A deadbolt cannot be moved to the open position except by rotating the key.

Look for a double deadbolt for enhanced security. This means there is a locking bolt on both sides of the crossbar. Locking the shackle on both entry points greatly improves twisting and cutting resistance. Even if a thief cuts through one end of the shackle, it’ll be much harder to twist the shackle out of position.

Some brands even offer quadruple deadbolt systems which lock the shackle to the crossbar in four places for maximum resistance.

Construction

Lock Material

Almost all D Lock shackles and locking mechanisms are built out of steel. However, some locks will be constructed from hardened steel. By tempering steel if becomes harder and less brittle making it much tougher to cut through.

Some locks use tempered steel for improved strength

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.

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.


Mounts

If you commute to work or use your bike daily, then having a mount to fix your lock to your bike frame is a great way to improve portability. Many brands will include easy to use frame mounts with their D-Locks but check the product description first.


Frame Protection

D-Locks with vinyl covers, moulded end caps and rubber coatings all ensure that your bike frame is safe from scratches and damage to your paintwork.
