Product Information

Full details

The Zefal K-TRAZ U13 Lock is designed for cyclists in areas with a moderate risk of theft, offering a robust security solution with its high-resistance hardened steel construction and powerful double locking system. Its primary benefit is strong protection against impacts and twists, though users should be aware that its security level (13) is best suited for temporary stops rather than long-term overnight storage in high-risk areas. Key features include its durable U-lock design, an included adjustable mount frame, and a system for key duplication.

Troubleshooting

Lock is difficult to open or close

Ensure the key is fully inserted. Try lubricating the keyhole with a graphite-based lubricant. Check for any debris obstructing the mechanism.

Mount frame feels loose on the bike tube

Re-adjust the frame pieces to ensure a tight fit on the tube. Tighten any integrated screws or clamps on the mount if applicable. Ensure the selected tube diameter is within the 20-80mm range.

Key will not turn in the lock

Verify you are using the correct key and that it is fully inserted. Try wiggling the key gently. If the lock has been exposed to harsh elements, clean and lubricate the mechanism.

Lock mechanism is stiff after exposure to weather

Clean the exterior of the lock and apply a graphite-based lubricant to the keyhole and the moving parts of the locking mechanism. Work the lock a few times to distribute the lubricant.

Setup, Compatibility & Care

Setup:

  1. Mount Installation: Identify a suitable tube on your bike frame (e.g., downtube) with a diameter between 20mm and 80mm.
  2. Attach Frame: Slide the mount frame onto the chosen tube. Adjust the frame pieces to fit snugly.
  3. Secure Lock: Place the K-TRAZ U13 lock into the mounted frame when not in use. The frame is designed to hold the U-lock securely during rides.

Compatibility:

  • The mount frame is compatible with most standard bike frame tubes, accommodating diameters from 20mm to 80mm.
  • The lock itself is a standalone security device suitable for securing bicycle frames and wheels to stationary objects.

Care:

  • Cleaning: Wipe the lock and mount frame with a damp cloth to remove dirt and debris. Avoid using harsh chemicals, as they can damage the finish.
  • Lubrication: Periodically lubricate the keyhole and locking mechanism with a graphite-based lubricant to ensure smooth operation, especially in wet or dusty conditions.
  • Inspection: Regularly inspect the lock for any signs of damage or wear. Ensure the mount frame remains securely attached to the bike.
