High security certifications and approvals

This model benefits from SRA Class certification (Sécurité et Réparation Automobile), the most demanding standard on the French two-wheeler lock market, as well as the ART 4-star rating attesting to exceptional resistance to brutal attacks. These certifications are recognized and recommended by insurers, facilitating theft coverage for your bicycle. Auvray, French leader in locks for over 30 years, guarantees this product for 10 years, proof of its confidence in the durability and effectiveness of its design.

Mechanical performance and resistance to attacks

• Reversible Ø16mm shackle in passivated hardened steel: ultra-resistant material offering optimal protection against sawing, cutting and picking attempts. The matte black PVC protective sleeve prevents scratches on the bike frame
• Double hardened steel locking mechanism: reinforced security making any break-in extremely difficult, even with specialized tools
• High security 7-disc cylinder: designed to resist the most sophisticated drilling, extraction and picking techniques. Integrated anti-picking protection
• Anti-rotation shackle device: exclusive technology preventing shackle rotation in case of sawing attempts, thus blocking the thief's action
• Hardened steel body: increased robustness against impacts and destruction attempts by percussion

Dimensions and everyday use

With its internal dimensions of 80 x 150 mm, this compact U-lock allows you to effectively attach the frame or rear wheel to a fixed point (hoop, post, street furniture). Its medium format limits the space available inside the shackle once the bike is attached, preventing the introduction of a jack or lever by a thief. Its weight of 1.43 kg remains contained for a lock of this security level. The ABS end caps protect your bike from impacts, while the dust cover on the keyway protects the locking mechanism from weather and extends its lifespan.

Key system and practicality

The lock is supplied with 3 reversible milled keys, usable in both directions for quick and hassle-free locking. An exclusive key copy service by code allows you to order replacement keys at any time, ensuring lasting security. The matte black finish with yellow accents offers excellent visibility and a modern design recognizable from the Xtrem Bike range.
