OnGuard RockSolid 8590

Add a little sparkle to your security. A diamond coating contributes to the unbeatable security of the OnGuard RockSolid 8590. Over the years, we’ve introduced you to many of OnGuard’s collection of cycling locks and this most recent release looks to be the most secure ever built. A steel shackle with a proprietary coating that blends ultra-high strength materials containing ceramic and diamonds ensures your bikes safety. Cordless angle grinders are a common tool that thieves use to cut bike locks, and the RockSolid 8590 has been tested to resist these types of attacks. This is a robust lock, weighing in at 3.1 pounds, making it the lightest angle grinder-resistant locks on the market currently. It comes with 5 keys, a co-moulded crossbar cover and double rubber coated shackle to keep your bike’s finish pristine from scratches or damage, and a patented X4P Quattro Bolt which secures both sides of the shackle to the crossbar in 4 places, creating a double-redundant system resistant to pulling, jacking, prying, and twisting. Get peace of mind and maximum security with the OnGuard RockSolid 8590.
