OXFORD GP Chain 8 200 cm

La spécification « Diamètre de la chaîne » indique l’épaisseur effective de la chaîne, exprimée en millimètres (mm). Cela permet de déterminer à travers quelles ouvertures la chaîne peut être passée, comme les trous de ventilation d’un disque de frein, entre les rayons, autour du châssis ou d’un point fixe. Plus le diamètre est important, plus la chaîne prend de place et plus les possibilités de passage peuvent être limitées. Vérifiez donc toujours que l’ouverture disponible est suffisante pour le diamètre indiqué.

The length indicates how long the cable or chain is according to the manufacturer’s specifications. It determines how easily the bicycle, scooter or motorcycle can be secured to a fixed object and how much flexibility you have when locking it.

• Short length: suitable for securing the vehicle in a compact way, such as around the wheel or frame. These lengths offer less flexibility but are usually lighter and easier to carry.
• Medium length: provides a good balance between flexibility and ease of use. Ideal for securing the vehicle to a pole, fence or other fixed object without becoming too heavy or cumbersome.
• Long length: offers maximum flexibility for securing the vehicle to larger or more distant fixed objects. Due to the extra length, these cables and chains are generally heavier and less compact.

The ART certification is one of the most important standards for chain locks and other locks for two-wheelers such as bicycles, scooters, and motorcycles. The ART Foundation tests and certifies locks for theft resistance: the more stars a lock receives, the higher its security. Below is an overview of the different ART levels and what they mean.

ART 1

• Meaning: Basic protection; guards against simple and quick force.
• Use: Short-term parking in well-monitored or private areas.
• Insurance: Often not recognized by insurers.
• Security: Easily forced with basic tools; minimal protection.

ART 2

• Meaning: Standard protection against limited professional tools.
• Use: Short-term parking in areas with some supervision or locked garages.
• Insurance: Sometimes recognized for basic theft coverage.
• Why: Offers slightly more resistance but still vulnerable to targeted attacks.

ART 3

• Meaning: Enhanced protection against more advanced tools and longer attempts.
• Use: Unmonitored public areas for short to medium parking periods.
• Insurance: Usually recognized by insurers as minimum requirement for motorcycle theft coverage.
• Why: Good balance between usability and security for standard motorcycles.

ART 4

• Meaning: Advanced protection; resistant to professional tools and prolonged attempts.
• Use: Long-term parking in public areas or for valuable motorcycles.
• Insurance: Recognized by most insurers; often required for higher policy values.
• Why: Provides strong resistance against professional tools and significantly delays thieves.

ART 5

• Meaning: Maximum protection; tested against advanced methods and professional tools.
• Use: High-end or expensive motorcycles; maximum security required.
• Insurance: Required by insurers for full coverage of valuable vehicles.
• Security: Offers the highest theft resistance, minimizes risks, and meets strictest insurance requirements.

SRA certification is an official French approval for motorcycle locks. SRA stands for Sécurité et Réparation Automobiles, an independent organization that tests locks for resistance against theft.

A lock with SRA certification has been thoroughly tested against various attack methods such as cutting, sawing, pulling, prying, and cylinder manipulation. Only locks that meet strict standards receive official SRA approval.

• Yes: The lock is SRA-certified and complies with French security standards. This may be required by certain insurers, especially in France.
• No: The lock does not have SRA certification. Check with your insurer whether this is required for your policy.

SRA certification is mainly required by insurers in France but can also serve as an additional quality guarantee in other countries.

This specification indicates the type of two-wheeler the chain lock is primarily suited for, based on size, strength, and usability.

• Bicycle: Bicycle chain locks are usually lighter and more compact, making them easy to carry. They provide sufficient protection for bicycles in urban environments or for short-term parking.
• Scooter: Scooter locks are generally slightly stronger to resist cutting or pulling. The length is usually adapted to secure the scooter to a post or fence while remaining relatively manageable.
• Motorcycle: Motorcycle chains are typically heavier and more robust, with a larger diameter to secure the higher value and weight of a motorcycle. They are suitable for longer parking periods and public locations with higher theft risk.

Note: This specification was added by our product specialists and is not binding. All locks can be used on all types of two-wheelers, depending on your preference for portability and security level.

The weight of a chain lock is an important factor when choosing the right lock. Weight is usually indicated in grams. Heavier locks generally provide more resistance against theft but are less convenient to carry. Lighter locks are easier to carry but offer less protection against professional tools.

Here is a breakdown of weight categories:

• 0 – 2 kg: Ideal for short trips or as a portable solution. Easy to carry but limited protection against professional tools.
• 2 – 4 kg: Good balance between portability and security. Suitable for daily use and for securing bicycles, scooters, or light motorcycles.
• 4+ kg: Provides a high level of security. Especially suitable for motorcycles or vehicles of higher theft value. Less convenient to carry.

Tip: Choose the weight that suits your situation: for daily commuting, a lighter chain may be sufficient, whereas a motorcycle parked on the street is better secured with a heavier lock.

This specification indicates whether the chain lock can be attached directly to the brake disc of your motorcycle or scooter. Some models combine a chain with a disc lock, offering maximum flexibility and security.

• Yes: The lock is a chain-disc lock combination. You can loop the chain around a post or other fixed object and secure the vehicle via the disc lock on the brake disc. For added convenience, the chain can also be removed and the disc lock used independently.
• No: The lock is chain-only. The vehicle is secured by looping the chain around a fixed object, without direct attachment to the brake disc.

This specification indicates whether the lock is equipped with a built-in alarm function. In addition to mechanical protection, an alarm can provide extra deterrence by emitting a loud sound when movement or tampering is detected.

• Yes: the lock features an integrated alarm that is triggered by unauthorised movement or tampering. This increases deterrence and visibility during theft attempts, especially in public or busy areas.
• No: the lock relies solely on mechanical security and does not include an alarm. This version is simpler, requires no battery and is suitable for users who do not need an audible warning.
