What does this have to do with locking your rear bike wheel through the rear triangle but not around a frame tube or stay? I was simply amazed at how few hacksaw strokes it took to get through the rim. So a thief with a common hacksaw could easily walk off with your whole bike in proabably a minute, albeit with a ruined rim, tire, and tube, but still a nice piece of pilfering.
