Technical Information

1
Safety
Contrary to what many people may think, no lock is fully tamper-proof. A bike lock is there to make stealing the bike more complicated, to delay the thief, and therefore act as a deterrent. A good lock has an anti-picking lock mechanism and is made out of materials requiring the use of specific tools, making theft more difficult.
2
Security rating
The security rating helps you choose the lock that is most suited to your use. To accomplish this, B'Twin defined a test protocol jointly with an independent laboratory, CNPP, based on real-life theft techniques. This unique protocol allows each lock to be given a comparable rating indicating how resistant it is to theft. This rating ranges from 0 (least secure) to 10 (most secure).

Je n’ai pas essayé personnellement de le couper... difficile de donner un avis de résistance pour le moment...
L’allure générale est plutôt convaincante en terme de solidité relative. En revanche les parties métalliques ont tendance à abîmer le cadre du vélo. Il serait de bon ton d’envisager « d’enrober » ces parties d’un revêtement plus doux.
Le prix au vu du niveau de sécurité avancé par Decatlon est particulièrement agressif ! Je recommande !!

Plus pratique qu'un antivol en U, la chaîne permet d'être transporter assez facilement en l'enroulant sur le cadre et le poids est donc supporter par le cadre. La longueur suffit pour attacher facilement le vélo à n'importe quel point fixe. Le cadenas s'ouvre très facilement ; les mécanismes sont bien huilés.

Cadenas assez résistant mais la serrure semble fragile et la clé a parfois du mal à être insérée.
un peu lourd

Cette chaîne est un peu lourde mais c'est le prix de la gloire
A résister à au moins une tentative de vol
Used for More than 2 years
Voila plus de 4 ans que je l'utilise, le plastique est complétement cassé suite a une tentative de vol il y a 3 ans, mais il fonctionne parfaitement. je l'enroule autour de ma selle pour le ranger et je peux facilement prendre le cadre et la roue avant.
