Last year I bought a 2016 Giant TCR Advanced 2. With the documentation in a small plastic bag came these two small pieces of metal with a spongy sticker on them.

One is slightly curved the other is flat.enter image description here

What is their purpose?

    Hahaha. I was going to say they look like currency coins to me! ... until I realized you included the money just for size purposes. – RoboKaren May 7 '17 at 21:12
  • Totally unrelated to the question, but curious... Is that the British 50p piece? – FreeMan May 8 '17 at 11:59
  • @FreeMan it's a 20p coin – Joe Lee-Moyet May 8 '17 at 13:02
  • Thank you, @yjo. I've often heard British F1 commentators describing a flat-spotted tire as being like a 50p piece so I thought this was it. I guess I'll just have to Google an image for myself to see the difference... – FreeMan May 8 '17 at 13:28

These are to protect your frame from the support bolt on Shimano front derailleurs (I don't know if SRAM have the same).

You can see them on page page 7 of this manual.

  • Nice, certainly one of the more niche parts! – Ben May 7 '17 at 16:10
