This is turning into a great thread. Please post more pics, especially if you have something unusual or attractive. I hadn't seen the Sekine disc, and agree that's amazing and should absolutely stay on. I seem to recall seeing some attractive versions put out by Huret and/or Simplex, and someone mentioned a Campy version which I seem to recall. I'd love to see pics of any of those.

I agree that the plastic versions don't look so good when yellow or greasy.

I got my first lightweight when I was 13, a Schwinn Le Tour Luxe. I completely disassembled that bike the first winter I had it, and the first bicycle specific tool I purchased was a freewheel remover - so I could remove the spoke protector. I don't know why, but even as a youngster I didn't care for the look. I used to always toss them out, but now wish I would have saved them. I did keep the last couple of jumbo-sized chrome steel Schwinn versions to decorate the garage wall with. Like many here, I'm more open-minded now, and would love to see more pics on bikes.

Thanks!
