No way, I would have left that out, even if it was locked. Didn't see a full shot of the bike, but I can see it had brifters and was pretty handsome. You should only lock up old beaters. If had that bike, and if I did lock it up, I would be looking at it from a window or something. No way it would be out of my sight, even with a lock.
Sorry for your loss, but please, learn something from this loss!!
