I need some plain grey brake cable housing for my Frejus Tour de France. It doesn't need to be totally period correct, but I'd like it to look pretty ok. My usual go-to source for this sort of thing is Porkchop BMX, but the description in this case suggests the grey cable they have is more silver than grey. (It looks pretty grey to me, but kinda dark.) Any other sources where I can buy something by the foot which might look a bit better (not as dark, and not "silver")?
