High security certifications and approvals

• SRA (Sécurité et Réparation Automobile) Certification: approval recognized by all insurance companies, guaranteeing a minimum resistance of 10 minutes against any break-in attempt
• ART 4-star Certification: European quality label certifying a high level of protection against theft
• FUB 2-wheel approval: recommended by the French Bicycle Users Federation
• 10/10 security rating: the highest level of protection in the AUVRAY range, suitable for high-value bikes and e-bikes

Reinforced construction and anti-theft technologies

• Ø 16 mm reversible shackle in passivated hardened steel: exceptional resistance to cutting, sawing and twisting attempts, with anti-corrosion treatment for long-term outdoor use
• Double hardened steel locking mechanism: secures both ends of the shackle simultaneously, making any attempt at wrenching or levering extremely difficult
• 7-disc high-security cylinder: pick-resistant and drill-resistant design withstanding the most sophisticated break-in techniques
• Integrated anti-rotation device: in case of partial sawing of the shackle, it cannot rotate to allow the lock to open
• Monobloc hardened steel body: maximum robustness against sledgehammer blows and destruction attempts

Finishes and everyday practicality

• Matte black protective sleeve: full coating of the shackle preserving the paint and finishes of the bike frame, discreet and professional appearance
• Reinforced ABS end caps: increased resistance to weather and wear, optimal protection of the locking mechanism
• Dust cover on key passage: protects the cylinder from external elements (rain, dust, frost), extending the life of the mechanism
• 3 high-precision milled keys supplied: always a spare copy at hand, optimal manufacturing quality
• Exclusive code-based copying service: possibility to order additional keys via the unique engraved code, without the need for an original key
• Mounting bracket included: allows you to carry the lock directly on the bike frame during travel
