I dont know if its a law in the U.S. but I seem to remember every bike I have ever gotin has had reflectors on it when I took it home from the LBS. I see that just about ever bike on here dos not have any reflectors. why dos every one talk them off? I have been out a few times where it has gotin dark and I had wished that my hole bike was covered in reflectors. dos it add the much wait or do people think it just look stupid?
