Swapped from black to silver on my ride. Black ones are used, silver ones are new.
For a 1 1/8th steer tube.

3x 5mm (all black)
2x 10mm (one black, one silver)
1x 15mm (silver)

Feel bad "selling" them, per se. Buy me a coffee or trade some other junk I may need (brake cables/housing, 4 matching bottle boss screws... idk? Try a trade)
