Erg79--Very unlikely imo and here's why. There are only 3 methods quick enough for thievery that will defeat the ulock. 4 foot bolt cutters (maybe), bottle jack, battery grinder. The first is somewhat expensive and (more importantly) very risky to carry/use. And how stupid is pulling a car with plates up to the bike in a peopled area? (In order to hide the cutters) The last 2 are really expensive. A standard size bottle jack is too long to use in any alignment other then one that will ruin the frame and the little 3.5 " one is $200.00 and only available mail order. (Also the mini ulock doesn't give enough room even for the stubby jack, a big plus for the mini size). So the point is..., anyone who has set themselves up to do one of the above is serious and will have aquired the very minimal mechanical knowledge required to recognize the sheldon method as only realistically defeatable if one is willing to lose value of rear wheel and even then very noisy and a hassle, plus one is back to using an identifiable get away car. YOMV but for me any extra weight/bulk is just not worth this very small risk. Course, if you are riding a "1%er" bike.......
