Hmmm ... That's a new one. I broke down, and bought the OnGuard Bulldog LM STD U-Lock after just using a Master Lock cable all last summer. I got very lucky that nothing happened to Lola! After the pain in the ass time I have had trying to transport the u-lock on Lola, even with advice from all of you (thanks btw), I finally broke down & got an Abus Cable Lock Rack Bracket Set. I ended up using it for the first time this past Tuesday, and really like it. I think it is one of the best purchases I have made thus far. I do not keep the lock on the bracket set when I have it at home, because I do not watch to put unnecessary strain on the brackets if I don't have too, although they look like they will hold up well.
