A trusted original in the Neo Chain family, the ULAC Street Fighter is designed for riders who want simple, secure protection without the bulk. Made with 5mm heat-treated hardened steel links, it offers dependable resistance against cutting and pulling—perfect for quick stops and low to medium theft-risk areas.

At just 540g (1.19lbs), it's ultra-lightweight and easy to carry. The included ULAC Velcro strap lets you attach the lock anywhere on your frame or seatpost, or just fold it up and stash it in your backpack. The 100cm (39.3in) length provides enough flexibility for locking to racks, railings, or posts, while the resettable 4-digit combo lock offers up to 10,000 combinations for key-free convenience.

Wrapped in a soft nylon sleeve to protect your bike’s paintwork, the Street Fighter is the perfect everyday lock—compact, strong, and easy to use.
