The OnGuard Bulldog LS U-Lock delivers strong, extended-length protection for cyclists who need more locking versatility without added weight. Its 13 mm hardened steel shackle resists cutting, prying, and leverage attacks, while the X2P Double Bolt system locks both sides of the shackle to defend against twisting and pulling. A Z-Cylinder core provides anti-bumping and anti-drilling reliability, and the rubber-coated crossbar protects your bike’s paint and finish. The 340 × 175 mm (13.4 × 6.9 in) frame provides extra reach for securing to larger racks or posts. Includes five laser-cut keys (one with LED light) and a universal mount bracket.
