Kryptonite's Transit FlexFrame U-Bracket makes it easy to carry your U-lock on your bike so it's always handy. This simple mount fits on frame tubes from 25 to 80mm in diameter and it accepts most 13 and 16mm-diameter round-shackle U-locks. Plus, the clamp rotates so you can perfectly align the lock with your bike to keep it tucked out of the way.
