Tubular shackle made of hardened steel for superior strength and durability.

Supple rubber coating to stop the lock banging against your bike and damaging the paintwork.

The security rating helps you choose the lock that is most suited to your needs.
For this reason, B'TWIN defined a test protocol with an independent laboratory, CNPP, based on real-life theft techniques.
This unique protocol allows each lock to be given a comparable rating from 0 to 10 indicating how theft resistant it is.
