I've had the same 7 beads - 2 orange, 2 green, 2 blue, and 1 pink - on one of my bikes since I was about 7. Just keep putting em on my favorite bike at the moment. They have always brought me good luck - I have ever gotten hurt riding the bike they were on. My grandpa got them for me, so they also mean a lot. In the past 20 years, none of them have broke, and now I feel weird on a bike w/out them. I've grown to love the noise they make, and they seem to fit my style, too...
