Tony, I once had *Zefal Lock and Roll locking skewers*. I still have a few. You turn the bike upside down, put them on like a normal skewer, then flip your bike upright. As long as the bike is upright, you cannot open them. I think the mechanism is a little ball bearing inside the cam or something that blocks the lever until you flip the bike upside down again, and then you can open the lever like normal.
However, they are easily defeated I hear by using a magnet, and also, once mine got jammed and would not open no matter what I tried, so I used pliers to unscrew the skewer from the non-lever side. No problem to get the nut off and the wheel removed that way. So they are defeatable pretty easily it seems, and they do get stuck shut sometimes. I would think that 90% of the time they would avert theft. But any thief who notices the purchase providing nut on them could just unscrew the nut if he wanted the wheel bad enough. Some people do know about the magnet trick, too. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
