Thats the thing chris667, most modern rims are lightweight, and the strength comes from the shaped internal bridge, and tyre inflation. Old rims were heavy monstrosities, which would have any thief just walk on by. But faced with a lightweight race bike, with lightweight wheels, .....out comes the boltcropper, or battery powered angle grinder, and that wheel would be history. And the rest of the bike would be gone. Easier for a serious pro thief to steal another rear wheel from someone who felt a cable lock was good enough.
