Secondary lock

Bought this to supplement my Tank grade DLock and keep my wheel secure (Not long enough to do both wheels in situ & frame but I knew that prior to purchase). Tough but smooth material covering the chain so it won’t scratch your paintwork. Great value and hope it deters any ‘have a go’ scumbag.

No se ajusta a la descripcion. No atas dos bicis, ni una sola cuadro y rueda a una señal. Tuve que devolverla y encima, para variar, en la tienda no habian largas. Mal

Es muy buen candado, sólo que pesa mucho. Pero da seguridad al candar la bici

Candado fuerte

Parece bastante seguro. Suficiente para asegurar la bicicleta a un aparcabicis o una señal. No llega para atar las dos ruedas y el cuadro ( pesaría muchísimo y sería poco práctico) Durante la marcha se enrolla alrededor del cuadro de la bici y no molesta.

Security rating

The security rating helps you choose the lock that is most suited to your needs. 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), 10 being fully theft-proof.
