Abus Granit 460
This D-lock / U-lock is great for bikes or situations where you need a bit more room in the shackle. The inside of the shackle measures 109mm wide by 230mm long.
Like all the Abus D-locks, this locks at both ends of the shackle, which means you'd need to cut both sides in order to open it.
Comes with a mounting bracket that fits on frame tubes 15-35mm diameter.
