ULAC EUROSTILE CHAIN LOCK NEO
The Versatile Urban Essential.
The ULAC Eurostile Chain Lock Neo is a classic, key-operated chain lock that balances security with daily portability. As part of the Neo Chain Collection, it features a vibrant, weather-resistant nylon jacket designed to add a splash of color to your bike while serving as a soft barrier to prevent scratches on your frame.
At the core of the lock is a 5mm heat-treated hardened steel chain, providing a significant upgrade in security over standard cable locks. It is designed for riders who prefer the reliability of a high-security dimple key system over a combination dial, ensuring a quick and solid "click" every time you lock up.
Key Features
Hardened Steel Protection: The 5mm induction-hardened links offer dependable resistance against cutting and tensile attacks.
Weather-Resistant Nylon Sleeve: The high-quality jacket protects your bike's paintwork and ensures the chain remains durable in outdoor conditions.
Anti-Dust Keyhole Lid: Features a protective cap to keep dirt, rain, and road grime out of the cylinder, ensuring smooth long-term operation.
High-Security Dimple Keys: Comes with two dimple keys offering up to 500 unique combinations for improved picking resistance.
Velcro Storage Strap: Includes a dedicated ULAC strap, making it incredibly easy to fold and store the lock on your frame or in a bag when not in use.
Lightweight Utility: Weighing in at just 545g, it is light enough to be wrapped around your seatpost or top tube without affecting bike handling.

✅ Why This IS For You
Cafe & Quick-Stop Riders: Ideal for short-term security where you need a lock that is fast to deploy and easy to carry.
Style-Conscious Commuters: If you want a lock that matches your bike's aesthetic, the Neo Collection's diverse colors offer more personality than standard grey locks.
Key-Preference Users: Perfect for those who find combination dials finicky and prefer the tactile security of a physical key.
❌ Why This May NOT be for you
High-Theft Urban Areas: While hardened, 5mm links can be defeated by power tools or large bolt cutters. For overnight city parking, consider a thicker ULAC Diesel 7mm Chain.
Forgetful Key Owners: If you frequently lose your keys, a combination-based lock like the ULAC Street Fighter might be a safer bet.
Extreme Weather Exposure: If you live in a coastal area with high salt spray, even with the dust lid, a silicon-overmoulded lock provides even greater corrosion protection.
BFC Pro Tip
The Eurostile is the "Goldilocks" length at 100cm—long enough to loop through a wheel and frame, but short enough to be worn across the body or wrapped twice around a seatpost. To keep the mechanism in top shape, a quick spray of Teflon-based lubricant into the keyway once every six months will prevent the internal pins from sticking, especially if you ride in dusty or wet environments.
