Bests & Worsts Reviews from Amazon

I bought this for a girl's bike to fit on my rack. Works great. The only problem is what other's say. The pin you insert will scratch the frame of your bike. I had been just using tape to protect the bike. I was thinking of idea of using a plastic tube to cover it, but then it wouldn't allow the pin to slide through the frame of the adapter. So I decided to use wire heat shrink wrap. I used 3/8 in and worked perfectly. I was worried it might rub though and get back down to metal, but since the wrap is pretty thin it didn't. I have used it about 10 times and works perfect. Check out my pictures I posted.
