Product Details

This lock set pairs an 18.76mm U-lock shackle (25mm hardened steel) with a 14.73mm carbon steel body and a 4ft braided steel cable, so you can secure the frame and a wheel at the same time. Silicone coating protects your bike's paint and keeps the lock quiet on rides. Includes 2 keys.

FAQ

How many keys come with this lock?

Two keys are included, so you can keep a spare in case one is lost.

Is the included cable as secure as the U-lock itself?

No — the cable is meant as a second layer for the front wheel while the U-lock secures the frame and rear wheel, not as your primary line of defense. See our bike locks guide for why pairing two lock types beats relying on either alone.
