Product Information

Full details

The Oxford Sentry 2.0 U-Lock is designed for urban cyclists who require a balance of robust security and portability. It offers high-level protection with its hardened 13mm shackle, making it an excellent choice for securing bikes to fixed objects in moderate-risk environments, though users should be aware that the rigid U-shape requires careful positioning to find compatible locking points.

Extended Product Information

FAQs

What is the Sold Secure Silver rating?

It is an independent security rating indicating that the lock has been tested against specific tool-based attacks and is suitable for moderate-risk areas.

Can I get a replacement key?

Yes, the lock includes a unique key code. Keep this code in a safe place to utilize the Oxford replacement key service.

Does this fit all bike frames?

The bracket is designed for standard bike tubes; however, unconventional frame shapes may require additional padding or alternative mounting locations.

How do I maintain the weatherproof shield?

Ensure the shield is pushed fully shut after removing the key to prevent water ingress.

Is the 13mm shackle heavy?

It is robust for security, but the included frame mount is intended to distribute this weight effectively while riding.

Troubleshooting

Key is difficult to insert or turn

Clear any debris from the keyway and apply a small amount of silicone-based lock lubricant.

Mounting bracket rattles during rides

Check that all mounting bolts are tightened to the frame and ensure the lock is snapped firmly into the bracket cradle.

Cannot reach the anchor point

Always attempt to lock the rear wheel and frame together to a lower section of the bike rack to minimize the distance between the bike and the anchor.

Pros and Cons

Pros

  • Sold Secure Silver rated for proven security
  • Sturdy 13mm shackle is highly resistant to cutting
  • Weather-shielded barrel prevents corrosion and jamming
  • Includes a convenient frame-mount bracket
  • Three-key set provides helpful backups

Cons

  • Rigid design limits flexibility compared to chain locks
  • Requires a suitable fixed object for secure locking
  • Bracket installation can be fiddly on some frame geometries

Setup, Compatibility & Care

Installation of the carry bracket involves using the included mounting bolts to attach it to the bike frame's water bottle bosses or a suitable frame tube. Ensure the bracket is tightened securely to prevent shifting during transit. Regarding care, the key barrel is weather-resistant but benefits from an occasional application of a silicone-based lock lubricant. This keeps the internal mechanism operating smoothly, especially in coastal or damp environments. Avoid using WD-40 or heavy greases that may attract dust and grime inside the locking mechanism.
