Thanks to everyone for their suggestions.
In response to one of the follow-on questions, I would be locking it to something stationary. In my case a wall mounted bike hooks (I'll see if I can find a picture to post later). Now that this has brought up I wonder how secure the wall mount is. No sense in buying the ultimate lock if the point I attach to is the "weak link". I better check.
So far I'm most intrigued by the Abus Bordo lock. I have read report about how easily cables can be cut. Maybe I don't need anything that secure but if I'm going to lock up my $2000 road bike then I'm willing to spend $50-100 on the lock. I guess the U-locks are the most secure but I really don't want to carry more keys. (It would be nice if you could get a common key among three locks.) Any thoughts on how secure the Abus Bordo is compared to a Ulock?
Thank you, Scott
