Sentry Duo



The Sentry U-Lock is a lightweight security product that has been awarded a SILVER rating by the independent testing service Sold Secure.

A hardened steel 12mm ⌀ shackle combines with a spring release mechanism in the locking bar to make this an extremely use-to-use product. The universal fitting bracket is compatible with all styles of bike and the vinyl coating will ensure that it does not scratch your frame. The lock comes in two sizes and can be purchased with an optional extender cable to keep quick-release wheels or other accessories secure too.
