Onguard U-Lock Key Rotorfit 55x55

This OnGuard U - Lock is perfect for disc rotor locking. It has a security rating of 80. The yellow - colored shackle serves as a clear reminder that the disc is locked. With a large 55mm x 55mm opening, it fits many disc and rotor openings. Its massive 16.8mm hardened steel shackle is highly resistant to cutting, prying, and jacking. The X4P Quattro Bolt locking system secures the shackle on four sides for top - notch protection. An included disc reminder helps prevent you from riding off with the rotor still locked.

Using this OnGuard U - Lock is easy. First, find a suitable disc or rotor with an opening that matches the 55mm x 55mm size of the lock. Then, insert the shackle through the opening and lock it using the X4P Quattro Bolt locking system. The yellow shackle is a great reminder that the disc is locked, so always check it before you start riding. Remember to use the included disc reminder to avoid riding off with the rotor locked. For maintenance, keep the lock clean and dry. You can use a soft cloth to wipe it down regularly. If the lock gets wet, dry it thoroughly to prevent rust and ensure smooth operation.
