The SHACKLE 14 D-Lock from Oxford meets the three most important requirements of a quality U-Lock:

Highly Secure: It comfortably surpasses Sold Secure's 'Gold' standard using a special 14mm hardened steel shackle and body mated to a simple yet powerful locking mechanism with 3 replaceable keys.

Easy to carry: Oxford has designed a unique quick-release carry stand that is both sturdy and very easy to adapt to a huge range of frame and seat post sizes.

Reliable: A premium pre-oiled locking mechanism is protected by a rubber overmolded body to cope with the harsh outdoor life the locks endure.

The lock is available in 2 sizes; the 260mm length is a good compromise for general use, while the larger 320mm should be large enough to encompass the wheel, frame and some street furniture. This model can also be purchased with a large 1.2m hawser cable, to extend its reach.
