left over from my recent Giant TCR bike build?
Looks like the little frame protector supplied that sticks to the frame to take the fd adjuster screw to stop it scratching frame
See page 9 - it refers to a backup plate - needs to be positioned where the screw touches the frame http://si.shimano.com/pdfs/dm/DM-RAFD001-02-ENG.pdf
If I can find my microscope, I'll let you know!
IIRC, its function is more to do with spreading the load over a larger surface of the frame than to prevent paint scratches My band-on bike doesn't have that screw on the FD and my braze-on bike doesn't need the small plate because the screw rests against part on the braze-on plate
It’s used to support the FD during changes by bracing it agaiset the seattube.
It is only necessary when the FD is a braised-on attachment rather than a band clamped around the seatpost.
If your FD is attached by a band then you don’t need it - unless you intend to sell the FD at a later date.
