I'm rebuilding my 1992 Saracen and now I need to choose what colour Brake and shifter cable to run. I'm torn between 3 colours so figured I'd ask the good folks here.
Based on the clean build you've got, I wouldn't personally ruin it with colour. Xtr grey or black for me. Not adventurous but I think would suit what you've built nicely.
As above looks tidy that, black for me or you could get away with a purple or blue but I think you'd need to match that with something else on the bike, ie purple / blue saddle, grips etc
