Well, do you? When you leave your bike all safe and sound, do you rely on locks with cylinder-type keys as security? It may be worth your while to have a look at the movies that are linked from this thread if you do: [URL]http://www.bikeforums.net/showthread.php?s=48e7ea037478ce12c576875292ead32e&t=66128&page=1&pp=25[/URL] I wonder if this is an elaborate windup, as these locks have been touted as being pick-proof for years, and a lot of "Sold Secure" bike locks use them - and to get a SS label they have to resist the attempts of 'professional theives' to break them for five minutes, iirc. What do you think?
