OXFORD GP Chain 8 200 cm

The chain diameter indicates the thickness of the individual links, measured in centimetres. This dimension is important to determine whether the chain can be passed through certain parts of the bicycle, scooter or motorcycle, such as a brake disc, wheel rim or a section of the frame.

• Small diameter: thinner chains are easier to pass through narrower openings, such as brake disc ventilation holes or between spokes. They are more flexible and easier to use, but generally offer a lower level of theft protection.
• Medium diameter: provides a good balance between compatibility and security. These chains fit through most rims and frame openings and offer reliable theft protection.
• Large diameter: thicker chains offer a high level of theft protection and can withstand more aggressive attack methods. Due to their size, they do not always fit through smaller openings and are often used around the frame or a fixed object.

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 a Dutch quality label that indicates the level of theft protection offered by a motorcycle or scooter lock. This certification is issued by the ART Foundation and is an important requirement for many insurance companies. The higher the number of ART stars, the more rigorous the testing and the higher the level of theft resistance.

• ART 3: three-star locks provide good theft protection for mopeds, scooters and bicycles with a high theft risk. For mopeds and scooters, insurers generally require at least an ART 3-certified lock.
• ART 4: four-star locks are designed for motorcycles and offer a high level of theft protection. They are suitable for use on the road and meet the minimum requirements set by most motorcycle insurers.
• ART 5: five-star locks provide the highest level of theft protection and are tested against longer attack times using heavier tools. Due to their weight, these locks are mainly used to secure motorcycles at home or at a fixed parking location.

The SRA certification is the French counterpart to the Dutch ART quality label and refers to an independent testing and approval process for anti-theft products such as motorcycle locks. SRA-certified locks are tested for mechanical resistance against sawing, drilling and other attack methods and are recognised by many insurers in France and across Europe as proof of effective theft protection.

• SRA Class: indicates that the lock has been tested and approved according to the stringent French SRA standards for theft resistance. A lock with SRA certification offers reliable protection against break-in attempts and meets security requirements set by many insurers.
• SRA & insurance conditions: similar to the ART system, some insurance companies in France and Europe require the use of an SRA-certified lock as a condition for theft coverage.

The application indicates which type of two-wheeler the lock is suitable for. Not all locks offer the same level of security or compatibility, so choosing a lock that matches the type of bicycle, scooter or motorcycle is essential.

• Bicycle: bicycle locks are designed for lower weight and a lower theft risk. They are suitable for city bikes and e-bikes, but generally do not provide sufficient security for scooters or motorcycles.
• Scooter: locks for scooters and mopeds offer a higher level of theft protection than bicycle locks, with a good balance between security and weight. They are suited to lighter motorised two-wheelers.
• Motorcycle: motorcycle locks are the heaviest and offer the highest level of theft protection. They are designed to withstand more aggressive attack methods and are suitable for motorcycles with a high theft risk.

The weight indicates how much the lock weighs according to the manufacturer’s specifications. This is an important factor when choosing between ease of transport and theft protection, especially if the lock is carried regularly while riding.

• Lightweight: lightweight locks are easy to carry and ideal for daily use or short stops. They offer greater convenience, but generally provide a lower level of security than heavier locks.
• Medium weight: these locks offer a good balance between portability and security. They are suitable for use on the road and provide reliable theft protection.
• Heavyweight: heavy locks offer the highest level of theft protection and can withstand more aggressive attack methods. Due to their weight, they are mainly used for home use or fixed parking locations.

This specification indicates whether the chain lock can be attached to the brake disc of the motorcycle or scooter. Some models combine a chain with a disc lock, allowing the vehicle to be secured both to a fixed object and directly to the brake disc.

• Yes: the lock is a chain and disc lock combination. The chain can be wrapped around a pole or other fixed object and secured using the disc lock on the brake disc. When not required, the chain can be left aside and the disc lock can be used separately.
• No: the lock cannot be attached to the brake disc. This type of chain lock is intended solely for securing the vehicle to a fixed object using the chain.

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.
