If the bike has high value components then it is worth wrecking the frame to strip them - a big pair of snips will cut straight through a bike's frame. This is why so many NYC couriers went over to fixies or ss. Less dramatically, brifters can be pulled off in seconds by experienced thieves and sell for several hundred dollars on ebay.

The only to reduce a valuable bike's strip-value is to uglify - polish off logos with a dremel and slosh expoxy on wherever you can. Dozens of hard to peel off stickers on the frame - as uncool as possible - will help prevent whole-bike theft too.
