That really sucks. I've had one bike and parts stolen over the years. Did you post on CL? There were two other posts today re: stolen bikes; both indicated they used u-locks and cables.
I see you posted on the stolen bike registry. Beautiful bike, too.

Do you have the serial? Ethical bike shops check serials. If there are used bike shops in your general area, you can drop in and leave a description. Not a lot else you can do. I did help someone reclaim a stolen bike that popped up on eBay ... I googled and the bike came up in a stolen registry alert.
There used to be an open-air market around 11th and Ave C, but not sure it's still there. Apparently, a lot of Manhattan bikes end up there.
Fingers crossed you find it.
