A 6 or 9 inch U-lock is much more secure, and can be fastened to the frame, or carried much easier. The circumference is certainly large enough to secure a couple road bike frames with a single wheel each to a'standard' bike rack or pole. It's perfect if security is your main concern but is a lot to carry around as you bike.

This is a pretty monster lock. The lock itself separates into two pieces, which can be difficult when you are trying to wrangle the two ends of the chain and the two lock pieces. It's also substantially lighter than the chain. This thing is very heavy.
