The ULAC Eurostile Chain Lock in Navy Blue offers a timeless, professional aesthetic for urban security. As part of the 5mm Neo Chain Collection, it provides a high-strength barrier against opportunistic theft while the deep navy nylon sleeve ensures your bike's finish remains unblemished.
At 100cm long, this chain is exceptionally versatile, allowing you to secure your bike to various fixed objects that shorter locks can't reach. The Navy colorway is a perfect match for riders who prefer a classic, understated look that still stands out more than a standard black lock.
Hardened Steel Links: Built with 5mm induction-hardened steel, providing reliable cutting and tensile resistance.
Weather-Resistant Nylon Sleeve: The high-quality navy blue jacket protects your frame and makes the lock comfortable to handle in all weather conditions.
Anti-Dust Keyhole Lid: Features a sliding cover to keep rain, dirt, and grit out of the cylinder, preventing the lock from jamming over time.
High-Security Dimple Keys: Includes two keys with an advanced dimple design, offering significantly better pick resistance than standard serrated keys.
Integrated Storage Solution: Comes with a dedicated ULAC Velcro strap, allowing you to wrap and secure the lock tightly around your seatpost or frame for transport.
User-Friendly Weight: At approximately 545g, it provides the physical security of a chain without the heavy burden of a motorcycle-grade lock.

Style-Focused Commuters: If you want a lock that matches a professional or classic bike aesthetic while providing dependable security.
Multi-Location Lockers: The 100cm length is ideal for riders who have to lock up to irregular objects like lamp posts or thick fences.
Keyed-Security Enthusiasts: Perfect for those who find combination dials frustrating and want the positive engagement of a high-quality key.
Overnight High-Risk Parking: For long-term storage in high-theft areas, we recommend stepping up to the 7mm ultra-thick ULAC Diesel.
Keyless Lifestyle: If you prefer not to carry extra keys, the ULAC Street Fighter Combo in Navy offers the same 5mm chain with a 4-digit combination.
Extreme Lightness: While 545g is light for a chain, those seeking a purely "cafe-only" lock for a lightweight road bike might prefer a thin cable or a small D-lock.
The Navy Eurostile is excellent for riders who use a front rack or basket. You can often loop the 100cm chain through the rack and the frame, then around the post, ensuring your accessories and frame are secured with a single lock. To keep the deep navy color looking its best, simply wipe the sleeve with a damp cloth if it gets splashed with road salt or mud during winter commutes.
