in the urban crime environment (portland!!), people steal components all the time. you can try some courier tricks to help deter this. candlewax in bolt holes or aluminum foil tapped in with a hammer or even a passes of duck tape work well. for the more desperate, a ballbearing glued into place has been done. a light lock eh? no exp. with the tigr. i use the candlewax trick, a bulldog mini and non/quick release skewers in most parts of portland without a hitch. combine this with a cable and you should be good to go in most parts of the country. dont tour the south bronx though.
